Quake Watch 2011

Confirmed dead now 65

Sadly, death toll in NZ is now being announced as 65 so far.
They are expecting many more.

The depth of these quakes is most concerning puterman/annmarie96/muzzy u people are expert,, as any other,,make the call. Should severe warnings be issued elsewhere? I trust your judgements.

Yeah, if you are looking on Google Earth, the epicentre is under the old crater walls of Lyttelton Volcano, the bigger one to the east is Akaroa Volcano.
Been through this when the Darfield Quake hit last year.Banks Peninsula used to be an island (of 2 sheild volcanos) and joined to the mainland through alluvial debris off the Southern Alps within the last 20,000 years.
The last eruption of either is estimated at 500,000 years ago.
Google or Wiki it

Stupid place to build New Zealands 2nd biggest city eh!

Well as far as I have observed there is nothing to suggest this quake will be responsible for anything else happening globally because of it.

Wasn't thinking globally,, was thinking more subsidence affects because of the depth.

What's with the double quakes today?

Just got up this morning and found out about this terrible event. So relieved that you and yours are okay.

I'm an Aussie and this is close enough to home. You're Kiwis and in truth we love you as our friends and neighbours.

Hugs to you...
Oh God I just don't know what else to say.

My Condolences (sp?) to everyone effected.

Interesting Read here . Especially the Article on Feb. 14,where there is a sort of "prediction" based on Facts and Data. And the Article "Earthquakes cause fault lines, not vice versa" from the Feb. 22. about Faultlines may be interesting for Robin,PuterMan and our other Semi-Experts.

thanks for the info Muzzy...I googled it and find this....:

Is the lyttelton volcano extinct?

Apparently yes, according to experts ... however in the latest Christchurch earthquakes, boiling water has been noted springing up all around it and some of the earthquakes were centered in and around Lyttelton. A strong smell of sulfur was also noted just after these quakes. The experts insist it is extinct but is there really any such thing as an extinct volcano?

appenently it has nothing to do with fault-lines... but it hangs moore to volcanic...

Death Toll Officially 32

What this means is that these people have been identified and next of kin notified.

11 more survivors pulled from the rubble overnight.
www.stuff.co.nz...

Mark Quigley was on the radio an hour after the quake, he said (without the opportunity to see the data) that this was a new Fault, a new event, not necessarily an Aftershock from the 7.1 in Sept.

I'm going to call it the Lyttelton Quake for now, the aftershocks on the 22nd are all along the Port Hills and Banks Peninsula, there have been no quake epi centers over to the west near the Darfield (Greendale Fault) at all.

reply to post by ressiv

Not necessarily.
The scientists here are suggesting that the Hikurangi Subduction Margin (where the Pacific Plate goes under the Australian Plate) has shifted South down from the Province of Marlborough to the Pegusus Bay/ Christchurch area, thus making these events Tectonic in nature.

query about post by muzzy

You'd think I'd get more than 2 stars for breaking the News first on ATS

11 minutes before Noinden's Thread Another quake hits Christchurch, now at 10 pages of replies and he/she/they got 27 stars

seems the ATS runs in clique groups, I don't recognise many familiar faces on that thread.

344 stars is not enough, I need more

Thanks for the extra stars

Well over here I think we are more into the technical side anyway.

Been watching the rescue effort on TV, its terrible, you feel like you should go down and help dig, but best left to the experts. Its 350km away anyway.
Aussie and American Rescue Teams have arrived to help and the Japanese not far away.

The Aftershock sequence confirms this is a new earthquake, it all over Lyttelton, Banks Peninsula, Port Hills and Pegusus Bay.
I've plotted 61 so far, there have been a few more added since I downloaded the data earlier in the morning, they keep squeezing in missed ones, that messes up my head.
I've loaded what I have anyway, for now, will do it again in the afternoon.
I haven't put the felt reports on the popup tags yet .............. do you realise how long that will take , I only want to do it the once, later.

7 days NZ so you can see the 6.3


Leading up to this I seen something on the 20th UTC that stood out and in hindsight I should have posted it here.
There was a sudden change in the Darfield Aftershock Series, a cluster in the Eyrewell Forest area, North of the Waimakairiri River. I hadn't noticed any aftershocks there before.
So it may be significant, perhaps that was the shift to a new fault.
Not sure how it works though, shocks move north then bang a new fault to the south east.

20th UTC Eyrewell Forest Cluster

Have just got our power back on.
Was horrible, horrible, feel so sad and am still waiting to hear from people Iknow who work in the City and in Lytellton.



This is our street. Water has diminished today and we've been trying to clear the drains. Burst mains, lots of liquefaction, but we're the lucky ones,as our house is fine.
Sorry, can't write much at the moment, just too upset.

So good to hear from you, Aoraki, to know you're safe.

I have finally accounted for all my missing friends, thank goodness. What a traumatic night, but nothing compared to what those whose loved ones are missing or dead. Dark days indeed.

Thank you for all your message and private messsages of support, very much appreciated.

Take care all you out there - and hug your loved ones a little tighter tonight, eh?

So Glad to hear from you too!! and So Glad your Okay!!!! Be Safe my friend.

I always keep a look out here in CA after a big quake happens anywhere else in the world -
we often see movement like this afterward - and it's always a firm reminder of how small our
earth really is.
