Quake Watch 2011

reply to post by PuterMan


I meant that we take the average across multiple agencies.

For example, for the Japan quakes we use JMA and USGS, and whoever else you want that could be considered an independent source. Simply convert each of their reported magnitudes to energy released, sum the totals together, and then divide by the number of reports used. Reconvert the energy released answer back to Mw and we've got the new Mats mag. Sounds like a pretty simple excel formula...hint hint. You da man.

I dunno, I'm having trouble co-ordinating the JMA pages.
This page www.jma.go.jp... shows the 7.1, 6.0, 5.6 and 4.7

But this page www.jma.go.jp... doesn't show any of them, in fact there is a big gap between 13:51 and 18:O5 JST

Wonder what "singendo" and "singen" mean thats the difference in the addresses of the page

the first page link shows intensity information, and the 2nd link just shows the epicenter location, but the lists don't match

I gonna try to stop ranting on here and stay on the topic of earthquakes.
So I started a new religion.
I can preach there.

www.abovetopsecret.com...

Looks like I might have to eat my words. Two days and no Oklahoma earthquakes.
I'll have to pray on it and ask my new GOD where I erred.

Robin, I think your on but I think you are off one week. - Look to next Thursday - IMHO.

I am quiet concerned about what is going on over in Japan. I am thinking more than I have time to put into words - Both plates - all plates in the area - helped along with the morons injecting god knows what to stop the nuclear meltdown which is only contributing to the quakes in addition to melt into the magma chamber, and like fracking allowing sea water in through the fractured rock as it melts. Folks IMHO we have a major, major issue here.... I have been quiet as I can see things and -- I don't want to fear monger - but geez, it's past that point.
Folks, please make sure you have your emergency supplies ready, buy extra canned goods, canned milk, bottled water, etc. now.... lots folks. Buy filters lots of filers for your tap water. .

Very. Very sad state of affairs we are dealing with at the moment!

This very recent Japan quake tonight...I'm wondering if this is the one that made the Japanese nuclear plant raise its threat level to 7, the highest level equal to Chernobyl

hi guys you may be able to help me. im looking for a thread that relates to people hearing like a vibration/humming noise. think it may be they were looking for connections to earthquakes. i only ask as people near the coast of sydney are reporting this noise this morning. thanks.

reply to post by muzzy


shingendo means shake intensity and shingen shin=shake gen=origin usually shingenchi is the word used for epicenter. I am sure it has already been mentioned but shindo is the japanese system for motion I think. I lived there 12 years and on the TV you always insantly receive a shingo 5 or whatever it may be, later followed by a magnitude which is usually about 1 over the shindo.

Sorry forgot to add...shingendo is not actually a word..should be shindou. meaning shake...and shingen means the epicenter or shingenchi. chi being land. Could be the page with shingendo in the url is for shake intensity and position and shingen page should be for epicenter....but just casually looking at it, that is not exactly how they worked it out. My brother in law from Tokyo just called and said..."enough already"

forever watching.

IMO, I think the situation over there has warranted the level being raised to 7 for some time now. I think they are raising it now because they have no choice.

With the sheer seismic upheaval they are facing over there, it is a very scary situation indeed. Radioactivity and tectonic forces do not mix well at all.

All we can do is pray that these eq's are not creating more pressure along other faults and under their volcanoes.

reply to post by lasertaglover


Agree

As another poster on a different thread stated, "The threat level has always been at 7. We are just now finding out", meaning that they are just now finally admitting to it.

A weak shindo 6 on the Japan scale just hit fukushima prefecture.......at 7 after the hour. I guess that is 6:07 UTC.

I've had a thread going about it for several months, there is a link in my sig. There have been a couple of other more recent threads regarding even louder rumbling in other areas. You should be able to find them by doing a search. Good luck!

I just posted some new maps and thoughts regarding the cascade subduction zone on my washington thread. Check it out!

Reported 4.3 Earthquake....

Guess where.....

Right on the "Cascadia Fault Zone"...

Keep close eye on the fault zone

If you are referring to this quake off the shore of Oregon:

That is most likely from the Juan De Fuca, not the subduction zone. You can tell by the location and depth. The ones coming from the subduction zone will be closer to shore (Or even a little inland) and deeper. Anywhere from 20 km to 50+ km deep.

Not that the quake isn't worth noting, just that it isn't doing anything to release that feared pressure building.

Me not like where this is going...

Edit: Next one could hit Tokyo if this keeps up...

edit on 11-4-2011 by Shenon because: (no reason given)

I knew it...(gonna praise myself here...called it yesterday)

Sorry for Double Post...

I don´t want to make a new Thread,but after connecting the Lines and a little out of the Box-Thinking,i think the next Big One (Mag 7+) should be around there (Black and Red Circles) Don´t like to call it a Prediction,because looking at the Locations of the latest bigger Quakes,its obvious where Stress "could" be released next.
