I want you to know I've thought about your words today several times. I remain silent and think of you. I want you to know that I'm sure many more are doing the same.

So sorry for your loss.
Thank you for the link to Dr Quigley's page. I will have a read of that soon.

As you're at the uni there, do you know of any studies being done about the environmental affects of the quake?
I have to do a GIS project for uni and am thinking of looking into this area. (it has to be environmental & and I want to do something about the quakes...any suggestions would be appreciated as I haven't been to NZ).

@ Muzzy. thanks for your info. Well done.

So sorry to hear about your friend, and all the others as well. It's a brand new day in a new journey for them now. May the wind blow their spirits to a place that is good and a new sun shine down on them in a field full of flowers blowing softly in the wind and all is good. So Mote it Be!

Good catch, and what a odd place, eh?

The link after the quake post shows the historical seismicity in this area, which looks substantial. I checked because this seemed out of place to me for a quake, but it is actually common here.

4.5Mw now.

Even though that quake is only 0.2 magnitude smaller than yesterdays Arkansas 4.7 the PGV (Peak Ground Velocity) was more than twice the speed. 5.4cm/sec versus 2.4cm/sec
PGV Geysers
PGV Arkansas

(for those not sure what it means the list is Longitude, latitude, cm/sec)

Therefore one would assume the damage would have been twice as much

Hey you guys, looking for some input on reading this seismo strip from GEE. This is a screen shot I took of GEE from the arkansas area. I zoomed in on it because it was so odd.

First, here it is at the 'normal' setting: (scroll to the right for the most pronounced spikes)




Here it is zoomed in:





This was showing up on several stations. What do you think?

Reminds me of radio interference. I posted a wavy seismo last week but I don't remember which thread.
Nobody said what they thought it meant so hopefully someone will be able to answer you.

Absolutely
if they were wanting to get away from earthquakes Wellington sure ain't the place to go


Felt that one

Had just got to sleep (I guess) and woke to the sound of the big mirror on the bedroom dresser rattling, I think I missed the main quake though, probably the rattling was the S wave. Just felt vibrations for a about 10 seconds.

I added this quake to a KMZ file I did back in 2009 with historical 5+ quakes in the Wellington/Cook Strait/Kaikoura/ZeehaensBight area. Doesn't include the Wairarapa and the 1855 Mag 8.0 on the western shores of Lake Wairarapa, but does have Mag 4's for the Wellington city and suburbs
KMZ CookStrait for Google Earth

It didn't convert to Google Maps every well, the icons are too big.

edit: Oh yeah, the highest PGV (Peak Ground Velocity) recording for that was at Frank Kitts Park right in the city, at 0.76483cm/sec (just a tiddler)

correction on post by muzzy
 

The PGV (Peak Ground Velocity) was higher at ARKS Wainuiomata Arakura School at 1.00428cm/sec


I don't know if I missed this when I first looked at it or it has been added in since, its on the opposite side of Wellington Harbour and behind the first set of hills, not where you'd expect the highest reading to be.
Lot more to this Velocity reading than I thought, unfortunately Geonet don't provide a list like USGS does, you have to look at the Shake Map and turn on PGV to see them.

Can someone with expertise tell me whether or not Southeastern Michigan is "safe" when and if something very major happens along the New Madrid fault line?

Thanks,
