Quake Watch 2011

I stepped away to feed the dogs and came back and saw the same signals. I have no idea where they are coming from as I came back in the middle so couldnt see what direction it hit first.

I am/was watching
Japan
Washington
Oregon
California
Utah
Wyoming
Idaho
Arizona
Texas
Arkansas
Baja
Mexico

the signal was on ALL of them

Hi Connie! Just wanted to welcome you aboard here. I'm also in Utah. Salt Lake Valley.

You've found a wonderful group of folks here who are ATS "legends"... well to me they are. Who help out here on a daily basis and provide wonderful insight! Don't be afraid to ask questions.

Again, welcome!

Just East of Australia ... a small group of islands. Im guessing those folks did not get much sleep.

as according to this site.

I'm not sure how they work out the seismic percentage, but these average activity areas?..they seem high to me.

(sorry they wouldn't stay in columns even after editing)
Does anyone know how they work out this statistic?

Not according to this page Phage.

Earthquake Facts and Statistics where they say 66, but that is not updated all that rapidly. The current total is 70 as of today and this quake:

Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2011-03-17T04:13:56.000Z,40.19770,142.20380,6.1000,25.3000,near the east coast of Honshu. Japan

My data also includes these three earthquakes which certainly won't be in the USGS database and may be contentious.

Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2011-02-21T23:13:30.642Z,-37.83740,176.18683,6.3000,169.2312,Oropi
2011-03-11T06:59:02.700Z,37.50000,144.87000,6.2000,40.0000,OFF EAST COAST OF HONSHU JAPAN
2011-03-11T07:55:15.100Z,45.48000,144.03000,6.1000,33.0000,HOKKAIDO JAPAN REGION

The first 2 are EMSC and the last is GeoNet.

If we take the current total of 70 and remove the latest as USGS won't have that on there yet, and then remove these three in contention I arrive at 66 which is exactly the figure that the USGS have.

As a matter of interest if anyone can throw any light on the contentions I would be interested to hear.

First
Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2011-03-11T07:28:12.000Z,36.80170,141.91060,6.1000,24.0000,near the east coast of Honshu. Japan
2011-03-11T07:55:15.100Z,45.48000,144.03000,6.1000,33.0000,HOKKAIDO JAPAN REGION
2011-03-11T08:12:04.000Z,36.60610,141.55730,6.2000,19.8000,near the east coast of Honshu. Japan

The middle one is the EMSC quake and appear to have no equivalent. Did USGS miss it?

Second
Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2011-03-11T06:59:02.700Z,37.50000,144.87000,6.2000,40.0000,OFF EAST COAST OF HONSHU JAPAN
2011-03-11T07:14:59.000Z,36.64840,141.81080,6.3000,25.0000,near the east coast of Honshu. Japan

The first one is the EMSC. Neither appear to have an equivalent in the other listing if you see what I mean, so is this 2 quakes? Looks like it.

Third
Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2011-02-21T23:13:30.642Z,-37.83740,176.18683,6.3000,169.2312,Oropi
2011-02-21T23:51:42.000Z,-43.58340,172.70120,6.3000,5.0000,South Island of New Zealand

The first is the GeoNet one. Is this the same as the USGS version??

reply to post by zenius


I have spent nearly an hour now trying to work out how they get to these figures. I cannot even get one to match, well actually I can get one which is the average of 6.5+ quake magnitudes for 2011 which they have as 6.9 and I agree with 6.8954.

Having said that.............Oh I just clocked what they are doing. I clicked on Italy in the Seismic world activity for earthquakes with more than 6.5 on Richter scale list and find that they are going back to 1857 for Italy. They are probably doing that for all regions and therefore you are correct, current figures will be very high.

This of course is just complete nonsense as they are not comparing like for like. In addition to which they are using magnitudes so as far as I am concerned anyway they are talking complete rubbish. How can you say that, for example, if there are ten quakes - 1 x 9, 2 x 8, 3 x 7 and 4 x 6 that the 9 is 10% of the total when it is 93.7% of the total energy released?

I would suggest that this site is not worth the web space it is taking up. My opinion of course. Feel free to differ.

They are well used to it. They probably slept through it! What with that and the volcano!

*note to self ... learn difference between West and East

Yes I have that problem as well, and also left and right.

reply to post by PuterMan


Hay PuterMan can you take a look at this and tell me if it is of any significance as there is discussion that it maybe a 7mag???? 30 whales stranded in Australia

I can't find anything on USGS, but had a look on GEE at station South Karori NZ. I'm just learning how to use GEE and interpreted it as a small quake or larger if some distance from station. (Thanks to TA's GEE thread)

Here is the image i grabbed from GEE at the above station:

Thanks in advance PM

EMSC can be just as 'bad' as USGS so I would not make that assumption.

By the way, for all you who have not looked at my signature note that it says Useful Earthquake and Volcano links. This goes to my blog and there are many many pages of links. All the hard work of finding stuff has been done for you , and as I come across one I don't have it gets added so the site is always growing.

Meanwhile, on the Elenin thread, this link to Impact Earth was posted. Get little toy!

I put in the size of Comet Elenin if it was to hit which it won't almost certainly, it could create an impact that was a 9.7 Richter hit!

Thank you. I should start reading sigs more often.

Thank you for that. I actually looked at Puterman's signature as well.

Has anyone read about this?

Underground quartz deposits worldwide may be behind earthquakes, mountain building and other continental tectonics, a discovery that may aid in predicting tremblers, according to a study released on Wednesday.

Scientists say quartz is key to understanding earthquakes

I saw that this morning. I was going to get around to posting it myself later this afternoon. It's an interesting read for sure.



EDIT: to add additional source

reply to post by PuterMan


Oh I thought it might be harmonic tremors. I don't know how to interept the seismograms. So there is no problem in Yellowstone?

reply to post by boo1981


Sorry, work and all that.

Something very small rippled through SNZO around 13:30 that is certain. Obviously a distant quake.

SNZO.IU.00.BHZ.2011.076

On the LISS version it is much clearer. Long drawn out P and S with the P beginning around 13:10

USGS are listing 1 quakes that I think will be the one:

reply to post by connieinutah


No, no problem based on that seismo, and none that I am aware of.

That particular pattern appears quite often.

This is exactly the same thing in Yellowstone from Oct 28, 2003 (and we are still here)



There are loads more, that just happened to be a handy one.
