Quake Watch 2012

reply to post by JohnVidale


Yes, Thank you. I am not anywhere near as knowledgeable than others who post in this thread.

But I was wondering about the mantle and if there is a difference in the type of material it is made of and whether there is a difference in how hot it gets or stays hot. Im not very good at explaining whats in my head, but I think I'm kinda on the right track.

Thank you again for your reply.

Thank you for your reply Muzzy. That was good.

I was reading about subduction zones and I got to thinking about why in some area's quakes were so deep and why. I thought about heat and then that got me thinking about what the mantle was made of. I kind of understand, but I have to go back and read some more.

Today in Iceland

Whole country - earthquakes during the last 48 hours




Earthquake count:
Magnitude less than 1 in all: 60
Magnitude 1 to 2 in all: 13
Magnitude 2 to 3 in all: 3
Magnitude more than 3 in all: 0

Total: 76


Looks like something is brewing, or what?

They have some very large, unpronounceable volcanoes there.
Is this similar to the activity prior to the eruptions that shut down air traffic over Europe? It would be a shame to interrupt the Olympics(tm).

Basically, the deep quakes are located where there are tectonic subduction zones. That is, where cold mantle is sinking, and it is still cold enough to be brittle and break in earthquakes rather than silently flowing, as it will do when it heats up to the usual temperatures in the mantle.

I think mine is prettier than yours, mind it is a bit older. Of course I could find some with really pretty reds all over them if I was to open up my archives.

I think the answer to that is "or what"

By the way it is spring and the icecaps are melting. The glacial load in lightening and this causes earthquakes. Happens again in October(ish) when the ice caps grow again.


Here is a link for a video I just made of the All Iceland maps for May 2011. Take a look as it hits May 21st in particular.

Hi Puterman

hi John,
Say,.. we have a few people on ATS makin predictions and havin bad "vibes" about a quake comin,,
Soon... like now till the 20th o may
any thoughts?

Oh for heaven sake. Got it! Depth.

Duh.....

reply to post by crappiekat


Depth , and Pressure!
Heres a pdf of a 2007 quake that has a cross section on it, you can see the shape of the Pacific Plate edge down to 660km or so
hazards.cr.usgs.gov...

is this the area you are talking about?

edit: heres an old sketch by GNS
www.gns.cri.nz...


if you have the bandwith available (23MB)
this is an awesome pdf map with cross sections right around the SW Pacific
hazards.cr.usgs.gov...


I just love those pdf maps that USGS put out, if you are into them too heres the ftp page where you can download them.hazards.cr.usgs.gov...
Rather than click each one to see what its about, probably easier to do a search for the date on Wiki or ANSS to see what it is first.

This one is about the Arkansas Swarm of 2010 hazards.cr.usgs.gov...

No credible precursors are visible to me. Unfortunately, every day has about the same odds as every other day, unless a big quake just happened.

Nice maps Muzzy. Since you are without a doubt the resident expert on the SNZO squiggles what do you think of this one?



That is Easter Island, but considering how far away from SNZO Easter Island is that seems a very large spike for a 5.2 (mb) I would have put that (at the distance) as probably a 5.9 Mw to 6.0 Mw.

It even shows in New Mexico quite well. (And on many others)



Don't look like no 5.2 to me.

Here is is from Las Campanas, Chile.




Answering my own question:

Geofon 5.9
Of course EMSC is following the Master as usual with 5.2mb: Pathetic really.
Russia also showing 5.2mb - but then they are wanting to cooperate with the US on space-flight.
LDEO

2012 5 10 2 13 52.0 -29.50 -112.50 33.0 5.9 EASTER ISLAND REGION

Once again the complete BS of not being able to calculate on a common scale (Mw) becomes apparent again. If SCARDEC and GeoFon and LDEO can do it so can USGS and EMSC but they don't and I think there is an agenda there.

As I have said before, after JVs comment on the reliability of Mw where there is a small set or low magnitude, better to publish on a common scale and give a value for certainty as well as publish the mb than to ignore the Mw and let people who are not aware think it was a 5.2

Either ALL mb or ALL Mw but preferably both in all instances with a certainty weighting if you like, or use mb < mb 5.0 and calculate Mw for ALL mb > 5.0. It is not difficult, it just requires a little methodical application. Oh wait, these are scientists.......

So when they count for the statistics what do USGS use?

Scrapped the post: Having a bad hair day! I think Firefox is steadily getting as bad as IE because the problems with the USGS interactive page are not apparent in Chrome.

PuterMan, I believe that you may have uncovered the problem...it's their FORMULA...they're not checking to make sure that they're actually acquiring 100% PURE hair of virgin!

Unless you pick and bag your own, you'll be scammed 99% of the time

Duh! Of course! I should have considered that.

In the meantime they are up to their usual tricks changing mb to Mw (see they can do it if they get the right type of virgin). Maybe they think no one will notice? Wrong! PuterMan will.

This was 5.6 mb and is now 6.0 Mw

On this occasion obviously the European virgin's hair was pure as EMSC always did have it at 6.0 Mw

Here is another one changed from 5.8mb to 6.0Mw and again EMSC always had it at that.

reply to post by muzzy


Thank you muzzy. I just got this. Have alot to look at. But yes this is what I was talking about.

Two more new Mag 6+ for April

M6.1 - off the west coast of northern Sumatra

M6.0 - off the west coast of northern Sumatra

These are Ms but since Ms compares well to Mw

Both of these are completely new additions and were not listed al lower values previously.

And another one not previously listed

M6.0 - Taitung City, Taiwan

Someone else had better check these out in case I am reading things wrong. I don't see any of these 3 previously listed at all.

And one previously listed at 5.9

M6.0 - Bandon, Oregon (off coast of Oregon)

EMSC always had this as 6.0 Mw




M6.0 - Santa Isabel, Mexico (Gulf Of California) down to 6.0 from 6.2.
but M7.0 - Santa Isabel, Mexico (Gulf Of California) is up to 7.0 from 6.9.

reply to post by PuterMan


why would it take a month for them to finally list those if they were not previously listed? any clue?

3.7 here in East Texas!! Not cool!! Too close for comfort...I should have felt it but I did not.. ?? Anyone else close to me that felt this here???

just a thought any fracking going on in that area? lol
