Quake Watch 2011

reply to post by UtahRosebud


Thank you very much for the info. Getting closer to me. It seems like the New Madrid is becoming more unsettled, all starting with Arkansas.

CrazyDaisy:
I know exactly how you are feeling. I, along with everyone I know and love live here. I cant imagine having to go through what Susan and the rest of the people in Arkansas are going through. Just waiting and watching on pins and needles...

Crazydaisy & Kennylee...

I suggest you both go read this post from Robin in the Arkansas thread. He posted it a little while ago.

Robin Marks Post in ATS Thread - Earthquake Swarm ....

Pretty recent Documentary from National Geographic about the Cascadia Zone and the New Madrid Fault(s),made after Japans 9.0. Lots of Info for you Guys.

Well, as is often the case (90% of the time) there were no "forshocks" as such to the 5.4 NW of Tokomaru Bay
New 7 day GIF up to end 25th NZ quakes

There was an aftershock though

II'm going to do one for japan, expect it will take a while, probably be more than 1MB, end of the month our ISP has reverted us to almost Diallup speed due to a cap on useage (reminds me of the 1970's an petrol rationing )

I do this every time we have a 5+, compile an updated file of events

As of March 27th 2011 NZDT
there have been;
6 quakes less than 1.0
585 quakes from 1.0 to 1.998ML
2729 quakes from 2.0 to 2.999ML
1034 quakes from 3.0 to 3.996ML
156 quakes 4.002 to 4.958ML
9 quakes from 5.011 to 5.91ML
2 quakes 6.343 (Lyttelton) and 6.351 (Atiamuri)
and 104 quakes of undetermined magnitude
in New Zealand and surrounding territorial waters (not including the Kermadec or Auckland Islands)

Muzzy thanks for posting your "new toy" quake map of NZ, and other NZ info. I'm in the North Island - supposedly in a quake-free zone, although there are faults deep below here i understand. Looking at the usgs world map each day, I'm seeing more and more decent-sized quakes from Fiji - south. I'm wondering if these are happening along the Kermadec trench? Do you envision these quakes moving southwards to NZ as time goes on, or are they just an adjustment after Japan?

That whole north east section of the Australan Plate from NZ north right around the top edge at Samoa and back west to Vanuatu is always pretty active, but it does seem to go in spurts.
I honestly don't think anything down this far is affected by what happened at Japan, in fact I'd say its the other way around. That Japan quake is likely due to spreading of the Pacific Plate, which expands in all directions.
I think you have to look at the bigger picture though, over many years and across at least half the globe to see the interaction of the tectonic plates with each other.

Now I've had a practice run with NZ and the Japan aftershocks, the next step is what I really wanted to do, the Global World Maps, which I already have made. I'm thinking to do them in 10 year periods, rather than the whole 100 years, because
1. the single 100year GIF would be massive MB
2. by the time you get to 50 years you've probably already forgotten the first couple of decades.

Its a work in progress, just like the planet Earth is

3.x miles in depth! wow. They are saying on TV a tsunami warning is in effect..

That would be REALLY bad, even if the waves were 2-5 feet, because it would push all that radiation covered water onto land... Hope there isn't one..

As soon as I heard about the tsunami following this quake I thought of the radiaition it could spread. This just gets worse every day. Also, that was a very significant quake that could have also done some damage.

Sorry can't get into Media at present so have to do it like this.

Looks like it is downgraded to a 6.1 and changed to 17.1km depth, but EMSC still had it at 6.5 at 6km depth last time I looked. USGS is using this weird Mi scale that I can't find anything about and EMSC are using Mb.

Shake map does not look bad

Someone posted earlier today from memphis, wondering if there was any quake activity near by.


Apparently a relative in a n.e. suburb of the city reported his house was shaking earlier today.


Can anyone confirm this, as I have not learned the ins and outs of GEE.


I am also in memphis but did not feel anything.

Wee cluster going on down Baja way...

Yeah I'm watching the So Cal popping also...

So far lots of smaller ones...

Puterman, that is an insane amount of instruments you posted on the previous page! - Not that I am complaining, but it makes me wonder why so many.

I have one of those dreaded headaches again today!!!
