7.6 Tsunami Alert ‘SAFE ~ tidal marine threat only’ #chch #eqnz #ChristChurch

Tidal marine hazard warning for north-east New Zealand coast – Reinga to East Cape – Stay out of the water and off the beach-line. Be Prepared for stronger than usual currents. Act with caution if boating. 7.03am Kermadec Islands magnitude 7.6 earthquake – moderate sea effect – see GeoNet record. Ref. New Zealand Ministry of Civil Defence and Emergency Management MCDEM.

At 5:26 pm 2011/07/06 Tsunami-Warn.com wrote to me for an exchange of web-links, which I am very happy to transact. 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.

Kermadecs magnitude 7.6 quake - USGS 070711

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?
Then a newer shot, capturing also the Kermadec 6.0 aftershock to the 7.6:

#Antarctic #warming new age of #volcanism

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

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.

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. …

Kermadec GeoNet no-show #2 ~ #eqnz

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:

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:

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.
