Interesting article, with some aerial photos of the fault trace.

f course, we're still getting aftershocks, but the recurrence interval is widening.

Nice work there, muzzy

Canterbury University homepage with some pictures of the damage in the library. I don't really want to think about the condition of my labs

Lots of cleanup to do there.
This is Ilam Campus?
I did the roof on one of the high rise buildings there back in the early 1980's ( past its warranty by 10 years now)

Its good how they are keeping you informed through their web site, quick work there.

MM4 Largely observed 2 Bucklands Beach [1], Grey Lynn [1] (Auckland)

There are a couple of felt reports from Christchurch, but thats unlikely given the magnitude and distance, probably just a mix up regarding time/location.

Okay, just gotta report that my dog is acting wierd again. Won't stop barking, growling for no reason.

Last time he acted like this was when they had the big one on the cali/mexico border. He's starting to freak me out though.

7:11 local time (pacific standard)

Kiwi friends - thanks for all the photos and links - I am glad everyone is okay, but how scary. The library photos are particularly compelling.

westcoast - all is quiet here... so far. Hope it stays that way - although, of course the next quake is just a matter of time

Yup! You got that right. I see you are in long beach!!

I just had a beautiful drive today that took me right past Mount Rainier. I actually stayed the night in Packwood that sits basically right at its base. I have to admit that I was just a little nervous, even though there hasn't been any sign of an erruption. It is an incredible sight up close!!!

I saw this on aol news online and thought I would share in this thread. I looked to see if anyone posted it but I didn't see anything. I don't know anything about earthquakes but it seems even scientists are puzzled. Funny thing is I found a thread from last year at the end of August where Oklahoma had a bunch of quakes that puzzled scientist then....so it happens again a year later and they are still puzzled?? So am I!

For all you quake buffs, what do you think this means if anything. Is it normal for this area of the US to get quakes?

For the second time in less than a week, six small earthquakes have been recorded in a single day in central Oklahoma.

The Oklahoma Geological Survey said the six earthquakes on Saturday ranged from preliminary magnitudes of 1.5 to 3.3.

Edit.
This is the thread I found from last year that mentions quakes in Oklahoma.
9 Earthquakes hit Oklahoma in 24 hrs (2009)

Do areas have cycles of the year where they are more active? I am only asking because I don't know anything about earthquakes and have always wondered this. Thanks.

Hi there, just some food for thought here on a subject i know
little about. Seems to me that on surprising regularity when
there is an earthquake within a day or so there is activity
directly on the opposite side of earth. Is this a known fact or
just my misconceptions? I have not documented any just
going off my memory, begs the question what or where is
the opposite side to NZ?

If you drilled straight through from Darfield you would be holidaying on the North coast of Spain.

Thanks puter, i was trying to work it out using my globe of the earth,
not real accurate, i was closer to greece. If Spain has a quake tomorrow
ill be a genius! Not that i would wish that on anyone.

Well I have to say that I can't see anything particularly unusual about the quakes in Oklahoma in terms of number or frequency. Whether they should be there or not is a different matter. You can see from the graph that the 71 quakes >= magnitude 1.0 over the past 365 days are relatively well spaced in terms of frequency and even in terms of magnitude.

Cumulative



Magnitudes



You would need to dig deeper into the geology of the area to take this a little further and I am afraid that just at this moment I don't have the time to do that. It does seem interesting having looked at those 71 quakes in Google Earth. They do all seem to be concentrated in one particular area. Any ideas what is out to the North WestEast of Oklahoma City? Oil fields? Extraction could explain this especially if this is an oil shale area which I suspect it would be.



You can download the KMZ file for Google Earth of those 71 quakes from my 4shared site

Couple of quakes just off the southern tip of Wellington 4.0 and 3.8, both Felt.
I didn't feel anything as I was driving at the time, but what may be interesting is at the same time there was a major landslide at Horokiwi which is right on the Wellington Fault. The motorway there was totally blocked and rush hour about to start
I cut off north before the landslide site.
On the radio when they reported these quakes they quoted scientists from GNS saying that "these quakes (and the east coast one) at 10:48am were not related to the Canterbury one."

Sure they weren't on the same fault line but surely subduction at the Hikurangi Trough will be causing all this activity, off course its related !

Where I am at Kapiti (north of Wellington) we are on the Australian Plate, the Cantabrians are on the Pacific Plate.

Hopefully this is just an minor adjustment of the Plates caused by the 7.0 at Christchurch.

Just read a post in another thread that said the innitial NZ quake caused a new fault line to form as well as 50 new ones along California.
Anyone know anything about this and/or if it's a load of crap?

reply to post by 5senses


From what I have read its not necessarily a "new fault" just a new fault "trace" ie evidence of a fault.

The fault may have been there for millions of years, been buried under 16,000 years of alluvial debris off the Alps.

The 50 faults in California probably another reseach project.

Yeah - that all makes sense. Thanks. Be safe

So, for the those of you familiar with the Deep Tremor - which was suppose to have gone through - we have todays (yesterdays) update - surley this has got to be stiring the faults and plate to a large event - why are we having uplift and tilt???? and "slip models"???? - walks away shaking head.

Sep 6, 2010 - This ETS seems to still be going on as strong or stronger than most. Strong and lengthy tremor continues to move slowly north on Vancouver Island almost reaching the Port Alberni area. The southern batch keeps moving south, now concentrated under Longview, WA. A report from Tim Melbourne of Central Washington University confirms this seismologist's suspicion that geodetic motions seem bigger than many ETS in the past. He thinks motions are on average 40% larger than seen in previous ETS including detectable uplift to the west of mapped tremor locations. Also his "Long Baseline Tilt meters show a beautiful recording (praise be summer weather), maybe 350nr of total tilt, and interesting time dependence." In another week or so some calculated slip models should be available.

Is this normal after a quake?
