Quake Watch 2011

reply to post by westcoast


Actually you know sitting back and being sensible about this without the tin foil hat..........

4.2 measures 21 pixels on screen
5.3 measures 567 pixels on screen
5.8 (off scale) but about 700+ pixels

5.3 is 44.7 x stronger then 4.2
5.8 is 5 x stronger than 5.3

It may look odd but it is probably right. We tend to see things normally like this (big 4.2 coming up)

I thought I had it wrong when you stated that before TA....because I had guessed the following couple of quakes accurately using the same station, based on what I am used to seeing.

As you can see by what I posted above...that is pretty typical. What you just posted...is NOT.

Something is VERY off you guys. What are we not being told, and why????????? We need to do some more digging....maybe sound analysis Puterman??

If anyone who has some expertise in this area of faults, liquefaction,and tectonic features,here is a nice little report relating to the recent quakes in Colorado and Virginia.

Data for Quaternary faults, liquefaction features, and possible tectonic features in the Central and Eastern United States, east of the Rocky Mountain front

pubs.usgs.gov...

If you have the time,that is.

And also a pdf map of earthquakes in Virginia and surrounding areas from 1774 to 2004.

BTW: The quake today looks pretty close to the central Virginia seismic zone.The get quakes there every few years,usually 4.0's.

I also noticed the close proximity in time between that last shock in VA and another Colorado shock. I have been seeing a similar situation often with quakes occurring close together like that in Japan and Chile.

Last time I used the word foreshock it was when the original 7.2 hit in Japan. And we all know what happened after that. So I am not even going to go there. If a 7.5 were to.... /preposterous thought...

Well if that is tsunami buoys (DART) then no but I throw a reasonable arrow (DARTS).

Weirdest thing is I said in the Altantic in the post BEFORE I saw yours.

Did the USGS just remove the 4.2 or is my computer being wonky?

Here's what was there a few minutes ago:

MAP 2.8 2011/08/23 18:46:50 37.931 -77.935 0.1 9 km ( 5 mi) SSW of Mineral, VA
MAP 5.8 2011/08/23 17:51:04 37.936 -77.933 6.0 8 km ( 5 mi) SSW of Mineral, VA

Here's what's there now:

Thanks for that indeed. Way too much to read tonight as it is 02:15 but I shall have a good read. Just skimming I noted the diagram of the fault scarp. I was sure I could see one of those on Google Earth by the 5.8 but I was not positive. Need to have another look.

Is it not possible that it didnt happen? that latest 4.2
Just askin

reply to post by Cherryontop


They did. 2 times, for 1st thought of browser cache so deleted. but the 2nd time confirmed it.

after 1st removal data source changed from USGS NEIC to CERI.

still available here earthquake.usgs.gov/earthquakes/recenteqsww/Quakes/se082411b.php

Okay, it IS gone now. I think it's coming and going....they must be unsure.

@lildrummerboy....yes, it happened. I have a screenshot of it on the previous page!

This is starting to feel like an Abbot and Costello routine!

reply to post by TrueAmerican


So basically as we thought it was less than a 2.5

They still have it in the 7 day text list however.

Strange! The 4.2 is gone on USGS but...it is being reported.? Hmm....I guess time will tell. Does anyone anticipate a "bigger" one somewhere coming or is it just me? I feel like I am on the edge of my seat.

Well the removal just confirms that it probably was not even a 2.5, cause it's off the main list.

Nice try USGS, but FAIL.
