Re: Christchurch imaginary killer tsunami

The 14 November early-morning debacle 2016, where false tsunami evacuation alerts panicked so many into a dark night after the Wairau 7.8-magnitude earthquake, was unacceptable waste and fear-mongering cry-wolf. Some had homes looted that public donations then had to compensate.[1] These Christchurch city alarms should not have been sounded for this event, two hours too late anyway. Many chose correctly to ignore them. What is going on? Blame government that does not seem to care or even know how to.

The fact is, government knew there was no tsunami risk from the first evaluation but still allowed the panic to waste massive time and resource energy:

The initial earthquake magnitude estimates ran:
http://ptwc.weather.gov/ptwc/text.php?id=pacific.TIBPAC.2016.11.13.1113 7.4
http://ptwc.weather.gov/ptwc/text.php?id=pacific.TIBPAC.2016.11.13.1150 7.9
http://ptwc.weather.gov/ptwc/text.php?id=pacific.TIBPAC.2016.11.13.1304 7.9

http://ptwc.weather.gov/ptwc/text.php?id=hawaii.TIBHWX.2016.11.14.0043 6.8
So the earthquake size was quite accurately known – until downplayed to 6.6 by GNS Science for days – and tsunami danger was accurately ruled out, by the global tsunami warning centre, from the very start.

The Pacific Tsunami Warning Cente 13.11.16 finding conformed with the actual known risk, as assessed by the local authority long-term:

Q-Files - Tsunamis extract Environment Canterbury p.8

Q-Files – Tsunamis extract, Environment Canterbury 2006, p.8

“If tsunami warning sirens sound, or you receive an official warning to evacuate, evacuate the coastal evacuation zones for your district.. You will have several hours to evacuate.. The most likely regional tsunami source for Pegasus Bay is the Hikurangi subduction zone fault, off the Wairarapa/Hawke’s Bay/East Coast coast.. A tsunami from this fault would likely take around 1-3 hours to reach Pegasus Bay. It is unlikely to be large here, but it may flood low lying areas around Sumner, the estuary and Lyttelton Harbour. Sea heights above sea level at the time here would probably be around 1-3 metres.. The chances of a local source tsunami being generated by an earthquake in Pegasus Bay are low and have not changed significantly as a result of the recent earthquakes. Scientists have discovered some earthquake faults on the sea floor in Pegasus Bay, but they appear to move very infrequently (once every few thousand or tens of thousands of years). They are not thought to be big enough, and therefore would not produce enough vertical (up and down) movement, to create a significant tsunami that would flood large amounts of land.. Tsunami sirens will be sounded for a distant source tsunami, where they are installed. If you hear the sirens, you must evacuate the tsunami evacuation zones for your district. You will have several hours to evacuate.”

http://ecan.govt.nz/advice/emergencies-and-hazard/Pages/booklets-q-files.aspx

Clearly officials panicked at seeing tide levels drop suddenly on 14.11.16, without knowing this was because of shoreline up-thrust. These officials then panicked others, and members of the public into leaving their homes unnecessarily, most ignorant of the actual low risk. The wrongly-imprinted hazard image – of a massively destructive high wall of water coming instantly ashore (like the Boxing Day 2004 Aceh, Indonesia or the March 2011 Sendai, Japan tsunami) – DOES NOT APPLY HERE. All this confusion should come out with the promised investigation of the 14.11.16 response. We live in hope, that it will be both a timely and productive investigation.[2]

The public should take from all this the lesson, to learn what actual tsunami risk exists for their home area and take appropriate precautions. Prepare appropriately and do not be panicked about imagined large tsunami risk in Canterbury ever again.

The difference is, the Alpine Fault is our tectonic plate impact zone – strong enough to build very high mountains (transform fault) – and this is the direct opposite kind of tectonic plate impact to that capable of producing tsunami (subduction fault). FACT. Fear not large tsunami here. Please do share and enlighten further.

The Civil Defence earthquake-tsunami mantra, “Long or strong, get gone” is not argued with here as potentially life-saving general education. But Christchurch’s experience of the 14.11.16 Waiau quake was ‘moderately long but not strong’ so it was not valid cause for fearful running from local shores or for official alarm-sounding. The alarm was therefore a misguided political act: to satisfy public expectations (of an alarm) incorrectly set. Let us work together now to repair this widely cast misconception of risk and relevant response.

Earthquake: Deaths, major damage after severe 7.5 quake hits Hanmer Springs, tsunami warning issued “One person died at a property at Mt Lyford, north of Christchurch. The low-lying seaside suburb of Sumner was deserted after residents evacuated, and schools closed for the day. Lyttelton tunnel has been closed until further notice. A New Brighton family who evacuated their home after the quake returned to find their house ransacked by burglars. Matt Mill said they family-of-four had left their home about 2am, after the tsunami risk was broadcast. They returned to their Bower Ave home about 6.30am to find their home damaged, not from the shaking, nor any tsunami, but by burglars who took advantage of a suburb empty of people. Mill said the burglars stole televisions, sports gear and distressingly, a transmitter for his daughter’s hearing aid. His work truck was also stolen. Linwood resident Alice Coats said the tsunami sirens have been going went off intermittently for a couple of hours. The quake felt like a long wave, Coats said. ‘So, we all knew it was a big one.’ As soon as the tsunami warning came in, it was a little more frightening, so she jumped into her car with her flatmate, and went to the airport. Coats said the vagueness of the Civil Defence warnings were frustrating. Tsunami sirens started sounding along Christchurch’s coastline at 2.14am. A significant amount of traffic moved away from New Brighton and other coastal suburbs towards central Christchurch and the Port Hills. Police and Civil Defence have closed the tunnel (State Highway 74), which links Christchurch with the seaside suburb of Lyttelton. The tunnel has been closed temporarily for checks following previous large earthquakes. In the CBD, hotels and occupied buildings were evacuated.” http://www.stuff.co.nz/national/86416268/Earthquake-Deaths-major-damage-after-severe-7-5-quake-hits-Hanmer-Springs-tsunami-warning-issued 14 November 2016 +
Earthquake: Tsunamis hit, warnings downgraded “Several evacuation centres had been set up in the Waimakariri district, north of Christchurch. Welfare centres had been set up at the Woodend Community Centre, Rangiora Baptist Church, Oxford School Hall, and the Kaiapoi Rugby Club. Linwood College has been set up as a evacuation point for people who have left their home in Christchurch.. People living on low-lying ground within one kilometre of the Christchurch coastline had earlier been advised to evacuate inland or to higher ground as a precaution. Tsunami sirens activated at 2.14am in Christchurch’s coastal suburbs, more than an hour after the first tsunami warnings were issued by Civil Defence. The sirens, located from Brooklands to Taylors Mistake, were meant to sound for about 10 minutes to alert residents they could need to evacuate. A significant amount of traffic could be seen heading away from New Brighton and other coastal suburbs towards central Christchurch and the Port Hills. Early on Monday morning police were driving around the New Brighton area with flashing lights on” http://www.stuff.co.nz/national/nz-earthquake/86416653/cheviot-quake-tsunami-warnings-issued (oh-so-wrong?)

Coastal Christchurch residents criticise delay in tsunami warning system “A delay activating tsunami warning sirens could have been life-threatening to those living in Christchurch beach suburbs, residents say. Some are demanding answers as to why sirens did not sound until about 2am, two hours after the magnitude-7.5 earthquake struck and an hour after the national civil defence website instructed coastal residents to move to higher ground immediately. ‘Something needs to be done,’ New Brighton resident Shanna Howden said. If there had been a large wave, Howden questioned whether people could have escaped in time. Heavy traffic and bad roads meant it took 45 minutes for them to get out of New Brighton. ‘There must be a way to put something in place to make it a smoother process,’ she said. Tsunami warnings come from the Ministry of Civil Defence and Emergency Management (MCDEM) in Wellington but local authorities are responsible for civil defence emergency management in their own areas. MCDEM posted its first tsunami warning on its website at 1am. The warning was repeated at 1.30am and not lifted until 3.39am. In Christchurch, the tsunami sirens began at 2am and sounded well beyond dawn. However, messages sent by the ministry to the duty officer at the Christchurch City Council and the Canterbury civil defence emergency management group were less clear. Christchurch mayor Lianne Dalziel said she was more interested in learning from the experience than casting blame. ‘I don’t know what went wrong but it’s important we fix this.’ Canterbury civil defence emergency group controller Neville Reilly said the council’s duty officer had relied on the group’s advice. The group’s decision to wait a couple of hours before firing the sirens was done in consultation with a tsunami scientist but without the knowledge that MCDEM was already instructing evacuation on its website. ‘It would have been nice if there wasn’t the confusion coming from emails which were different from the website,’ he said. ‘The worst thing you want to do is cry wolf although safety is paramount. There’s no black and white.’ MCDEM was unable to respond on Monday.” http://www.stuff.co.nz/national/nz-earthquake/86439726/coastal-christchurch-residents-criticise-delay-in-tsunami-warning-system 14 November 2016

“Straw Man – please decommission the Christchurch ones too. They caused unnecessary panic and are not even required. Many hours to evacuate in the case of a large tsunami, and not required for local quakes – there is no sub-duction zone off the ChCh coast. And yes, im aware of the 0.5m tsunami from the Kaikora EQ. It was not worth evacuating thousands of people. There was more risk of death or injury resulting from panicking drivers doing dumb things. Also, Pegasus bay does not funnel the swell into a confined space such as little pidgeon bay either. Start with a little education a[nd] ditch this ridiculous culture of fear that we have developed.”

GNS Science head office, like most New Zealand government, resides in Wellington region. There, existential angst competes heavily with Auckland for economic weight and centre of gravity. So Wellington treats the South Island as a private back yard – to be seen, not heard, exploited for all it is worth and insistently ignored and mis-spoken for. ‘It is all about us’, believes the capital, almost always. This hard-to-dislodge perspective explains constant nonsense from official sources over the 14-Nov-2016 magnitude-7.8 earthquake, particularly where it actually took place (and what it did). You would think GNS could not read a map or never travelled a secondary highway, to have located this earthquake as “Culverden”. They have a convention of approximating, to name larger centres that people may have heard of, only. This generalising is unhelpful. Locating the historically-large earthquake accurately is key to understanding it and its implications.

This was a “Wairau” earthquake, as the epicentre map shows – so why aren’t the authorities saying that? Why has this earthquake become about “Wellington” and “Kaikoura” exceptionally? Yes, people have sadly died or become most isolated in the latter town, and have our condolences and full support through that, with buildings lost at both places. But this is governance by spin: intentional confusion to deflect risk – to benefit who, we may ask? Tsunami alarm and quake interpretation questions abound – what is really happening? Where is it happening? Public discourse to be urgently joined. Lives depend on getting this very public knowledge correct.

Journalists often muddy the water – Cheviot earthquake: Tracing the source of the 7.5 magnitude quake “It appeared to have been a complex earthquake, and scientists were looking into whether it ruptured two separate fault planes, or whether it could be considered just a single rupture. The epicentre of the quake was close to the Hope Fault. The Kaikoura area, where the Hope Fault went offshore, was strongly affected. Despite that, the pattern of events did not necessarily suggest a Hope Fault event, [GNS Science duty seismologist Dr Anna] Kaiser said. The Hope Fault was one of the major faults through Marlborough and North Canterbury that marked the boundary between the Pacific and Australian Plates. Those faults merged near Otira to form the Alpine Fault, which ran along the western edge of the Southern Alps. Looking back over hundreds of thousands of years, the Hope Fault was considered to have one of the highest slip rates among those faults. It was an important structure in accommodating plate movement in that part of the country, Kaiser said. ‘This earthquake occurred right along that line of very active deformation.’ The Marlborough fault system was a kind of transition zone between the Alpine Fault and the subduction interface between the tectonic plates under the North Island. ‘So far, it doesn’t look to be the Hope Fault, rather (and perhaps more concerning) it seems to have ruptured across the Hope Fault,’ USGS seismologist Professor Kevin Furlong said. ‘Most/many aftershocks extend to Cook Strait, implying that the rupture may have extended quite a bit to the north. One concern is whether this has involved any of the subduction plate boundary that starts up at Kaikoura and extends along the [east coast of the] North island. At a minimum, it may have changed the stress conditions on the main megathrust interface – we are exploring that possibility right now'” – deftly shifting the focus to Wellington.

Research https://www.gns.cri.nz/Home/News-and-Events/Media-Releases/Rutherford-Award 11 November 2016

Naming the river floodplains involved is extremely important as these often follow fault lines, in north Canterbury and Marlborough especially – a crucial point for understanding the moving landscape: what is moving, why and when. The Wairau event aftershock trace mostly identifies the Hope Fault, joining directly as it does the massive offshore-Kaikoura Hikurangi Trough (to the Alpine Fault). It is ultimately movement in this huge connected structure that we see affecting land. Seismic force and aftershocks moving in the direction of Wellington should not be confused with the substantive event, but they have been, influential as they are.

The zoom out illustrates two things: the offshore trench-fault that runs through land north of Kaikoura as the Hope Fault; that aftershocks are now reaching and accumulating stress along this at the Alpine Fault to the west.

GNS add to confusion – M7.8 Kaikoura quake the biggest since the Dusky Sound jolt in 2009 – 15/11/2016 “Named the Kaikoura earthquake, scientists are describing it as a complex rupture sequence that produced ground-shaking that lasted for about two minutes and was felt throughout the country. It was centered east of Hanmer Springs at a depth of 15km” https://www.gns.cri.nz/Home/News-and-Events/Media-Releases/M7.8-Kaikoura-quake 14 November 2016 – are they afraid of naming Waiau (and Hope)?

The focus is kept upon effects in the Wellington area – Seismologists record 2 metre shift south of Marlborough “The largest aftershocks were close to the Hope Fault, the line running across the centre of the map. The earth moved two metres to the north in Marlborough during Monday morning’s major earthquake, according to data from GNS Science.. the ground moved horizontally 2 metres to the north and vertically down a metre”

While At quake’s epicentre, residents of Waiau watch helicopters destined for elsewhere “Waiau, population 280, is slowly returning to normality following the 7.8-magnitude earthquake that struck five kilometres away.. The town’s water supply has been restored but a separate feed to all rural properties was badly damaged and still broken. [Hamish] Dobbie said the council was working “really hard” to assist farmers who were running low on stock water. He hoped to have the water flowing in about a week. It has been a bitter pill to swallow for the community already struggling through a drought – a disaster within a disaster. Farmers near Waiau waved desperately at helicopters headed for Kaikoura, hoping they would stop.. It was hard not to feel forgotten as helicopters headed for Kaikoura, considering that Waiau was at the centre of it all. ‘I feel Waiau was a bit left out,” [Brenda] Smith said. ‘Even when it was first reported it was so many [kilometres] from Culverden, so many [kilometres] from Hanmer. I get it, we’re all hurting and Kaikoura is isolated … but yeah.'” http://www.stuff.co.nz/national/nz-earthquake/86594300/waiau-farmers-face-weeks-wait-for-water + Civil Defence overhaul ‘inevitable’ after tsunami warning confusion: Govt http://www.stuff.co.nz/national/86441740/civil-defence-overhaul-inevitable-after-tsunami-warning-confusion-govt + Mayor thanks those involved in evacuation effort https://ccc.govt.nz/the-council/newsline/show/1186 17 November 2016

Quake sparked more movements in Marlborough faults than first thought http://www.radionz.co.nz/news/national/318248/quake-sparked-more-movements-in-marlborough-faults-than-first-thought 17 November 2016

“Scientists know a tide gauge at Kaikoura rose 90cm during Monday’s magnitude-7.8 earthquake, but that’s one of the few pieces of detailed data so far about how much the level of the coastline has risen. There is also information about land movement from a network of continuous GPS stations run by GeoNet and Linz showing a rise of around a metre at Cape Campbell, at the southern end of Clifford Bay. Data from the stations also show Cape Campbell moved horizontally northeast by 2-3 metres. ..Many anecdotal reports suggest a two-metre rise at the coast, and there’s even one report of a reef rising six metres”

Quake action formed Hanmer Springs but latest quake passed it by “The Hanmer Fault runs right through the township and is the noticeable rise you go up as you head north towards the pools. On the other side of the basin lies the Hope Fault, one of the major seismic features of the region which starts at the Alpine Fault near Inchbonnie on the West Coast and slices its way across North Canterbury before heading offshore just north of Kaikoura. It’s this eastern part of the Hope Fault that some scientists now believe could be at risk of rupturing if enough stress has been transferred on to it from Monday’s large quake.. GeoNet director Dr Ken Gledhill said the quake rupture took the path of least resistance northeastwards up the coast from close to Waiau where it began. ‘It’s kind of strange, it’s like the epicentre in this case is almost a meaningless concept.’ It’s where the action started but it must have started weakly and then slowly built up steam. So Hanmer just happened to be relatively close to where the epicentre, but not the real action, was. The real burst of energy that contributed to most of the magnitude was between Kaikoura and Cape Campbell. It raced up towards Cape Campbell and then it basically stopped.’ Fortunately, Cook Strait, with its offset faults, had acted like a barrier and halted the quake in its tracks, Gledhill said. It was the sudden deceleration which raised the coastal strip by up to 1 metre and shunted that part of the South Island 2m closer to Wellington, rather like a car braking sharply to a stop and the passengers being thrown suddenly up and forward. If you could create a big-enough map of the northern South Island and southern North Island you would be able to see how the islands have stretched, shrunk and otherwise changed shape since 12.02am on Monday. The quake moved Kaikoura about 1m further northeast and upwards 70 cm, and Hanmer Springs jumped east about 50 cm. Wellington and the Kapiti Coast are now 2 to 6cm further north, Christchurch and Banks Peninsula have shifted 2cm south and some parts of the West Coast are now 10cm closer to Canterbury than they were” http://www.stuff.co.nz/national/nz-earthquake/86554866/quake-action-formed-hanmer-springs-but-latest-quake-passed-it-by 18 November 2016

GNS Kaikoura shoreline movement, 14 Nov 2016

‘Startling’ rise of 5.5 metres in piece of coastline during Kaikoura earthquake confirms quake energy has spanned the Hope Fault – the Kekerengu Fault has just moved about 10 metres horizontally, or about half of its 20-25m known movement per 1,000 years. That much sudden, imminent movement is scarily awesome. Note the Hope Fault is near where shoreline rise has been the greatest, at 3-3.5 metres. http://www.stuff.co.nz/national/86703833/startling-rise-of-55-metres-in-piece-of-coastline-during-kaikoura-earthquake 21 November 2016

Greedy, short-sighted economic actors are multipliers of natural risk. Korean charter flights pulled post earthquake – “The tourism industry and government agencies were also deliberately calling it the ‘Kaikoura earthquake’ because referring to north Canterbury gave the impression that Christchurch had been affected, when it had not”
http://www.stuff.co.nz/business/86604299/korean-charter-flights-pulled-post-earthquake 18 November 2016

We must remember, and anticipate, the main event.

And the Wellington earthquake – in the South Island – origins.

This 7.8 was exactly where I forecast and warned of, as next in the Canterbury earthquake sequence we are – if lucky, or god will it – living through.

The Future of New Zealand’s Coastlines
“The massive uplift after the 7.8 magnitude quake has changed Kaikoura’s coastline significantly. With a new reef forming as the land moved up, by as much as six metres along the fault plain. But do we know what the future of New Zealand’s coastline will look like? Just-published tectonic research gives some insight into what sea levels could be in the future. And the satellitle observations show parts of New Zealand, are sinking at faster rates than others, and will be subjected to higher levels of future sea level rise. Co-author of the research is Professor Tim Stern, of Victoria University’s School of Geography, Environment and Earth Sciences.” – RadioNZ Afternoons 231116

A much less likely scenario than the previous two scenarios is that recent earthquake activity will trigger an earthquake larger than the M7.8 mainshock. This includes the possibility for an earthquake of greater than M8.0, which could be on the 'plate interface' (where the Pacific Plate meets the Australian Plate).

USGS 141116 mag-7.8 shakemap - Waiau

USGS 141116 mag-7.8 shakemap – Waiau – http://earthquake.usgs.gov/earthquakes/eventpage/us1000778i#map

This USGS shake-intensity map locates: a) the Pacific plate and Australian plate tectonic boundary; b) Wairau River as central to the mag-7.8 EQ fault action – confirmed (therefore USGS have this epicentre listed wrongly?)

Synchronicity with Alpine Fault movement is precise – “at least three past large earthquakes had occurred in the last 1250 years. These initial results confirmed that the Kekerengu Fault was capable of producing large earthquakes frequently (on average, about every 300 or 400 hundred years)” – how long delayed is the M7.8 Waiau flow-on effect, to an Alpine M8-9, being the only question. As in weeks, months, years or decades? … Further large stress input is not needed. – Kekerengu Fault has a Word to its Geologists http://info.geonet.org.nz/display/quake/2016/11/28/Kekerengu+Fault+has+a+Word+to+its+Geologists

10 faults known to have ruptured in Kaikoura quake, more likely “The quake started with the rupture of the Humps Fault Zone, near Culverden, [Dr Nicola Litchfield, head of the GNS Science active landscapes department].. said. That seemed to have triggered the next fault along, which had triggered the next one and so on all the way to the Needles Fault – the offshore continuation of the Kekerengu Fault. ‘The movement in each of those [faults] was big enough it triggered the next to go in the same earthquake,’ she said. The faults that went must have been ready to go. The large Hope Fault hadn’t ruptured. “Basically it jumped over the Hope Fault and didn’t rupture that except for a tiny bit at the coast,” Litchfield said. ‘In this area there are a lot of faults. The thing is before this earthquake we didn’t think so many were going to rupture in one earthquake. I guess that’s the big surprise.’ It was unlikely the combination of faults in the Kaikoura earthquake would be repeated. The Kekerengu Fault went every 300-400 years. In contrast, it wasn’t known how often the faults at the south of the rupture zone went, but it was thought to be thousands, or tens of thousands of years between ruptures.”

Central NZ tsunami risk may be higher due to undiscovered offshore faults “GNS Science geophysicist Dr William Power said the 14 November tremor provided an ‘interesting puzzle’ in terms of where the tsunami was generated.. the tsunami might have reached 4 metres in some areas of the Kaikoura coast. However, the fact the quake struck close to low tide and that the land was uplifted at the same time reduced the extent of inundation. ‘A better understanding of the fault movements offshore in the Kaikoura earthquake will help us better evaluate the tsunami risks in central New Zealand.'”

Extreme heat detected beneath the Southern Alps “New Zealand scientists drilling into the Alpine Fault on the West Coast have found much higher temperatures than expected – which as well as being scientifically exciting could also be commercially very significant for New Zealand. They’ve drilled nearly 900 metres into the Alpine Fault at Whataroa – finding geothermal conditions comparable with Taupo, but there are no volcanoes in Westland.

At the time it was not clear which page I should post this Auckland company link onto. Now it stands as 13.4 hours’ early warning for today’s 7:03am, near-local seismic event. Check out the impressive Tsunami-Warn service, a “global early warning and alert system [by] SMS text message” – read latest notice.

This momentary alarm follows recent escalation of Fiji area 5+ quakes, that was already amidst a period of heightened seismic activity on the north and east Australian Plate. New Zealand geology is ultimately affected by this type of movement, as I began warning eleven days ago: 5.7 south-west Tonga Trench ridge quake shakes NZ. Then two days ago, it was already looking like a ‘more noticable’ /serious? seismic brewing, which GNS Science advise us not to see: Taupo 6.5 quake not good news 4 ChristChurch or NZ. Three days ago, I showed precisely where to watch for any imminent local bad shakes again: Next ChristChurch 6+ quake (which is not starting to trend below the critical ten gigajoule daily Quake Energy release line again yet)

On Cashmere hill, the first high-frequency vibration burst came through from the Kermadecs at 7:45am.

N.B. fellow Kiwis – today’s Magnitude 4.8 – KERMADEC ISLANDS REGION 2011 July 06 21:25:04 UTC 9:25am aftershock does not even make it onto GeoNet’s radar! Nor this, a Raoull Island seismograph screenshot, taken 2 July and perhaps showing a clear foreshock to the 7.6 main shock, that had otherwise escaped all the published seismic records (and forecasting):

And what is the extra trace movement you can see here got going early, ahead of the large one. about 4:25am NZST for almost an hour, that has no obvious other global seismic record?

In the southern hemisphere, we are well into another week of heightened seismic activity; or so it seems from the many medium-sized (5+) earthquakes occurring here. There is an eerie subsurface resonance on two sides of the South Pole, with the recent Chilean volcanic eruption probably venting some displaced energy from March 11th’s Sendai 9.0, and definite ripples on the south-western Pacific. “The last eruption of Puyehue volcano was in 1960 following a 9.5 earthquake. An eruption began at Puyehue-Cordón Caulle Volcano on 24th May 1960. The eruption was probably precipitated by the great earthquake in Chile (magnitude 9.5) which occurred on 22nd May 1960. The eruption consisted of an explosive subplinian phase and the formation of a mushroom-like column 8 km high.” Current visual reference: Chile’s Puyehue Volcano Erupts.

~ Now there’s a very scary line-up indeed – the Earth is peeling like an orange? …

It won’t be anthropogenic global warming that ends human evolution, directly; it will be the toxic atmosphere spewed up by the new age of volcanism that global warming unleashes, alongside emmissions pollution and climate change.

The Earth has been there before, and this is the flipside of global warming – the natural switch for rapid cooling, by global ash-cloud coverage. Next comes The Snowball Earth “when the whole planet appears to have [been] gripped by colossal ice ages” (geology.About.com /controversies) after drastic reduction of oxygen-dependent life, like mammals especially livestock and us.

The plant kingdom can then recover the environmental balance that we previously enjoyed. (Ref. Lovelock and “Gaia” theory).

Here is a consequent forecast/prediction/prophecy that you can bank on: Mount Erebus and its neighbours will erupt increasingly: “The glacier-covered volcano was erupting when first sighted by Captain James Ross in 1841. Continuous lava-lake activity with minor explosions, punctuated by occasional larger strombolian explosions that eject bombs onto the crater rim, has been documented since 1972, but has probably been occurring for much of the volcano’s recent history” Global Volcanism Program

Buried Volcano Discovered in Antarctica “Under the frozen continent’s western-most ice sheet, the volcano erupted about 2,300 years ago yet remains active.. Brooding giant. Although ice buried the unnamed volcano, molten rock is still churning below.. discovery might explain the speeding up of historically slow-moving glaciers in the region.. hidden volcano doesn’t explain widespread thinning of Antarctic glaciers.. ‘This wider change most probably has its origin in warming ocean waters,’.. which most scientists attribute to global warming resulting from human activity, such as the use of fossil fuels..” LiveScience.com January 2008
Scientists Find Active Volcano in Antarctica “For Antarctica, ‘This is the first time we have seen a volcano beneath the ice sheet punch a hole through the ice sheet,’.. Heat from a volcano could still be melting ice and contributing to the thinning and speeding up of the Pine Island Glacier, which passes nearby, but Dr. Vaughan doubted that it could be affecting other glaciers in West Antarctica, which have also thinned in recent years. Most glaciologists.. say that warmer ocean water is the primary cause. Volcanically, Antarctica is a fairly quiet place. But sometime around 325 B.C., the researchers said, a hidden and still active volcano erupted, puncturing several hundred yards of ice above it” NYTimes.com January 2008

Antarctic volcano not melting ice “..Erebus was erupting when members of Capt. James Ross’ 1841 expedition became the first humans to see it. In fact, the eruption at that time was the largest ever seen. Ross named the volcano for his ship, the Erebus. He named another Ross Island volcano Mt. Terror after his other ship.

Palmer Station 12 hours later: small local seismicity that does not show up, or relate to any remote event, on the global record. i.e. keep watching Antarctic seismometers to better read Antarctica.

Of course, as with diurnal peaks and troughs of seismic activity, there are seasonal flows and ebbs of earthquakes too – all due to planetary warming (then cooling, in cycles). So we should not expect the heightened Antarctic volcanism until next summer, January to March 2012. Make your bets now. …

Following my alert at the start of this week, that preceded GNS Science’s quick explanation of last weekend’s shallow quake swarm beneath Lake Taupo, further Kermadec Islands magnitude 5 earthquakes are passing ‘unnoticed’ in New Zealand seismic records, though not overseas:

020611 magnitude 5.1 Kermadec Islands

020611 Pacific Rim - morning

Why is that the case, when again the Kermadec Trench effect can apparently be found on our coastal seismograph records? Here we see the above event at Kaikoura, at the eight-hour mark:

020511 Kaikoura seismometer

020611 Kaikoura seismometer


Time approx 8am NZST; further, long and steady tectonic grinding is evident. (Hawaii had two small quakes.)

And this too is probably today’s Kermadec quake – the odd-looking shape above ’12 hours ago’ – picked up from Christchurch vicinity, which is why I’m documenting concern..

With this onshore linked precedent?:
Magnitude 4.4, Wednesday, June 1 2011 at 11:45 am (NZST), 30 km north-east of Opotiki

I urge Kiwi north-east coast readers to keep good watch on quakes.globalincidentmap.com for signs of a Kermadec Islands fore-shock quake swarm, like the magnitude 5 swarm which preceded March 2011’s Sendai offshore magnitude 9.1 earthquake. This may prove to be your best warning, with possible ground-shaking, of devastating north-east coastal tsunami risk. Service is not in place to watch this hazard for you.

Revisiting, the Australian Plate seems to be showing increased activity north of Australia and New Zealand – with a Solomon Islands 5.4 (after yesterday’s offshore Chile 6.2). This may have seismic implications for both countries…

And something big – over 15 minutes of motion – was picked up around Northland, before mid-day NZST.

Tsunami alert in Northland a false alarm – really? Or has it picked up on something seismically significant? …

Apocalypse believers shocked after appointed hour passes 22 May 2011 “Marie Exley..’Some people were saying it was going to be an earthquake at that specific time in New Zealand and be a rolling judgment, but God is keeping us in our place and saying you may know the day but you don’t know the hour,’ she said Saturday, speaking from Bozeman, Mont. ‘The day is not over, it’s just the morning, and we have to endure until the end.’ On Sunday, a magnitude-6.1 earthquake struck near a group of South Pacific islands about 600 miles off New Zealand, but there were no reports of damage or a risk of a tsunami.

7.3 quake strikes outer New Zealand islands 29/9/2008 “A 7.3-magnitude earthquake struck near New Zealand’s remote and largely uninhabited Kermadec Islands early Tuesday, New Zealand’s GNS Science geological agency said. New Zealand’s Ministry of Civil Defense issued no tsunami warning following the quake, while the Pacific Tsunami Warning Center said in a bulletin on its Web site that ‘no destructive widespread tsunami threat exists based on historical earthquake and tsunami data’ for the Kermadec area. Only the Kermadec’s Raoul Island is inhabited, with up to six New Zealand Department of Conservation workers living there at any time. The Hong Kong Observatory said the quake was centered about 630 miles south-southwest of Nuku’alofa, Tonga and was recorded in Hong Kong at 4:19 a.m. Tuesday, New Zealand time. The U.S. Geological Survey put the magnitude of the quake at 7.0 and said its depth was 12.5 miles.” + Strong quake near Tonga prompts tsunami warning 19/3/2009 usatoday.com/news/world

A very apposite comment here – Disaster is very good for National Party business, and undertaking – their best /-: “Disaster Capitalism”

Addressing the National Party regional conference at the weekend, John Key did his usual "shucks, nothing to worry about routine" again. Just like his budget predictions, everything will work out fine. He cited EQC as an example of a "growth business". "Look at something like EQC, they've gone from having 29 people to something like 1500; that is a growth business.'' That is indeed exponential growth – EQC is now 50 times larger than it was a yea … Read More

Do you remember the hula-hoop, yoyo, etc, etc? Many a teenage craze ago.. (prototypes of today’s larger, typically New Zealand, cow-farming fad).. after a few weeks the ‘cool’ kids start despising the younger ones who are imitating them and making their pastime now seriously uncool, and abandon both. But why wait until then,.. it’s really dumb now! 😉 😀

Finally the city-trade focused Christchurch misleaders start to twig “It’s now thought that we are looking at a longer term seismic series”, but still Mayor Bob Parker [is] upset at quake data headlines – how many more have to die under his and Key’s morally deficient administration?
