350 Otautahi – Sustainable Canterbury mauriroawaitaha.wordpress.com/climate-change mitigation action – 24-09-2011 commuter rail workshop – 3pm-5pm at WEA, 59 Gloucester Street, Christchurch.

~ a 350-Otautahi 2009 team update workshop:
How to effect change in local government in support of cyclists and emission reductions more substantially.

~ Is the smart “350” cause/brand being dumbed down and diluted into a minority matter of consumer choice? Come help build real lasting change.

~ “350” parts per million of atmospheric carbon is the goal – to stabilise Earth climate – and how we get there demands innovation. “Moving Planet” mobilisation is one means, but are there others? Workshop on empowerment vs major emissions sources, 3pm @WEA 24.09.2011.

~ Consumers, you are victims, not the cause – tax/costs up, quality of life down – TO ACTION!

~ Another magnitude 4+ aftershock earthqauke has heralded Moving-Planet day here in Otautahi: stop them?

~ Come help build a Sustainable Canterbury: Moving-Planet.org/events/NZ/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.

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):

Raoul Island seismograph drum - GNS 020711

The Raoul Island 7.6 quake and aftershock pattern:

But here is the double shocker, the effect of the Kermadec magnitude 7.6 quake upon the other side of Antarctica, south of Cape Horn – Palmer Station:

Kermadec 7.6 - PalmerStation 070711

Kermadec 7.6 - PalmerStation 070711


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:
Palmer Station seismometer, Kermadec 6.0 - 070711

Palmer Station seismometer, Kermadec 6.0 - 070711

Let this be our triple alert, the effect of the Kermadec magnitude 7.6 quake upon Mount Erebus, NZ Ross Dependency, Antarctica:

Taupo mag 6.5 quake - Mount Erebus 060711

Kermadec 7.6 - Mount Erebus 070711
