That is something you don't see every day - UPGRADED!

This one was just waiting in the wings so as not to increase the 2010 figures!

Anyone have any info on damage?

Edit to say: Intersting. EMSC has it at 6.9

I was just about to reply to you when my Puter threw a wobbly and decided to crashify itself. Like frozen in time so it was!

Anyway....

where are the aftershocks? oO

Happy New Year Folks.

I have updated 'Loads of links' to point to the new 2011 versions of Quake Watch and Volcano Watch. I have also retained the links to the 2010 just in case you need them and have lost yours!

These and other ATS links are in the ATS Forums section.

Hi Puterman,

good to see the thread moving along well. That 7.0 in Argentina was strange... I have not found any data for aftershocks and you'd think there'd be something. But then, all of Sth America is very quiet right now (aside from that one pretty big quake, I mean).

Anyway this just in on EMSC's near-real-time world map:

Magnitude mb 4.8
Region ANDAMAN ISLANDS, INDIA REGION
Date time 2011-01-01 17:36:08.0 UTC
Location 14.51 N ; 93.05 E
Depth 5 km
Distances 310 km SW Pathein (pop 237,089 ; local time 00:06:08.0 2011-01-02)
255 km SW Labutta (pop 41,769 ; local time 00:06:08.0 2011-01-02)

The Andamans are always worth keeping an eye on because there's a dirty big subduction zone in that area. (viz Dec 2004 in that general region.) And at 5 km depth this was quite a shallow quake.

Oh, almost forgot to link to the SOURCE.

This quake's not showing on USGS yet hence the EMSC reference.

Way too deep to have aftershocks - at least for that area anyway. The 6.3 at Acre in Brazil last year did not produce any either and that was even deeper. You tend not to get aftershocks with the VERY deep ones. Spain last year was another of the top of my head.

They will both be in this which I was just came on to post

QVS 2010 Large Earthquakes KMZ for Google Earth

This is all USGS 6.0 earthquakes and upwards for 2010. (The 2011 file has been started. Thanks Argentina!!)

reply to post by PuterMan

Drat you beat me to the answer.
I agree
We often get 6's in the Bay of Plenty, NZ that are 200km+ or so deep that don't have any aftershocks either

About this Wyoming quake getting deleted. I noticed this sort of thing a couple of years back and at that time (June[ish] 2008) we saw this happening suspiciously often in certain US regions, namely Wyoming, NE Utah and also parts of Nevada if I recall. Anyway we started getting screen shots of any quakes that popped up as "new" in those regions and hence we soon had proof of some that simply vanished. There are a couple of examples posted in a thread here on ATS.

We also found examples of quakes that popped up on the US maps in yellow, meaning they got posted late. I noticed one that popped onto the map over six days after it occurred, and so it disappeared off the map again very soon.

This sort of thing seemed to die down quite a bit as the Bush administration drew to a close. So, while they might have used excuses along the lines of "technical problems" causing "non-existent" quakes on the maps (that they then had to delete), it is interesting that an impending change of government seemed to make these difficulties go away. Quite remarkable, really.

However, it would be hard to blame technical problems for certain quakes to pop up late on the maps -- as in the above-stated regions and also off the coast around Eugene near the plate triple junction there -- because other quakes in the same areas did pop up as per usual. Some, for reasons unknown, were "delayed".

So, it seems that the same little game may be starting up again. The only way to keep track of how active the "deletion or delay" game is now, is to get screen shots of as much data as possible for quakes in known "delete/delay" areas. This means shots of the maps and also screen shots of the data page, including the quake's unique ID number. Then they can be posted here if the quakes get deleted, and also posted when some pop up awfully late. (Like, days late!) Have to be quick, though. I've seen a quake pop up in yellow and then drop off the map less than two hours later because it was seven days since it (supposedly) appeared.

Granted, there are false quakes and non-existent quakes. Granted, some are mine blasts and they acidentally get through and get auto-posted on the maps and have to be manually removed and placed in the mine blast seismo listings. Granted, there can be system glitches that cause things to be shown on the maps late, but that sort of glitch should not allow one quake to be shown and another (occurring close to it half a day later) to not be shown.

There's been some hanky-panky going on. At least that was the general opinion.

So, keep an eye on those regions and sees how they go.

To WestCoast: hope things are staying quiet up your way in WA. I see it's getting a bit more shaky than usual down in SoCal but at least that's not exactly extra-ordinary there. I'm more concerned about further up the coast than way down around San Diego. Just my feeling.

I see you had one Geonet 6 in there, but you may have missed another one.
I saved the data when it happened, but its not on the database search results now, must have been downgraded


REF: 3219647/G
LOCATION: 49.37°S, 164.12°E

Total 40

edit: OK, ICY, at -49.37 south its outside the geonet search box which only goes down to -48.868, so it won;t show on the results.
I wonder how many quakes are missed like this? USGS obviously didn't pick it up.

Okay you guys, those Yellowstone thumbnails had me going there for about 45 seconds.


Check out the time stamps. It is the 7.0 Argentine quake. I know it looks massive on there.....but it was SOOOOO deep the whole earth is probably still ringing like a bell.

Another prime example of how it is ALL connected!!



Edit to add: it will be interesting now to see if there are any repurcussions from it

Personally I think USGS will pull that one back below 7.0. On the phases page it has the magnitude type as
MAGNITUDE 7.0 (UCMT) and 7.0ML, but the calculation id based on mb (285 station)
neic.usgs.gov...

So what do the Argentinians have to say?

La intensidad del sismo en la escala de Mercalli Modificada alcanzó el grado II III (dos a tres) en las provincias de La Rioja, Córdoba y Corrientes.

www.inpres.gov.ar...

either way I'll use it to kick off a map and chart for 2011 on my Mag7+ blog , after all 7.0ML is still a "very-strong" quake which ever way you look at it

Humorous interlude....

Happy New Year to my fellow quake watchers

www.stuff.co.nz...

Happy New Year all you quake watchers! I am mostly a lurker, only getting to one first when you are eating lunch or visiting the powder room. I do appreciate all the links you posted.

JustMike: If quakes appear and disappear, do you think they might me nuclear bomb tests? I would suspect that happening during the Bush presidency, but it isn't making sense under Obama. Didn't a quake in Iran disappear a while back? I think there were two and then it was only one. I wondered what happened.

At any rate, it's good the 7.0 was deep enough to not generate aftershocks or catastophic damage.

Actually USGS did pick it up but they are calling it a 5.7

We have to come to some sort of decision as to what to do about these differences.

I actually came to post the PDF of my 2010 report, but i think I may wait until tomorrow as i wanted to get it finished on my QVS Blog first.

Oh stuff it, you guys can take a preliminary peek. I shall be starting a thread however to set it all out.

Yup they get deleted, and they get posted late, but then GeoNet post very late as well. Alaska is another favourite late posting area. It can be a week or more sometimes.

The only way to keep track of how active the "deletion or delay" game is now, is to get screen shots of as much data as possible for quakes in known "delete/delay" areas. This means shots of the maps and also screen shots of the data page, including the quake's unique ID number. Then they can be posted here if the quakes get deleted, and also posted when some pop up awfully late. (Like, days late!) Have to be quick, though. I've seen a quake pop up in yellow and then drop off the map less than two hours later because it was seven days since it (supposedly) appeared.

My program will catch every single one of those (Edit. provided they happen within 7 days) because it downloads every five minutes and every revision and every deletion are stored. Nothing ever actually gets deleted. If there is a revision the old one is stored and replaced by the new one. If one is deleted it is stored and only then is the record deleted from the main file.

Currently I have 10,954 deletions recorded since 30 Dec 2008, 205 of those being in Yellowstone.

• Nevada - 696
  
• Yellowstone - 205
  
• California - 5439
  
• Chile - 27
  
• EMSC - 1152
  
• Alaska - 1384
  
• Indonesia - 51
  

To mention but a few.

I did have one period where a few may have got missed and also 1152 of those are EMSC. Additionally several of the EMSC ones were caused while I had some problems with the program and automatically deciding which were duplicates of USGS events.

I probably should go through the database and clean them up.

These are the counts of data I hold
QuakeData 463,841 - Earthquakes
TempData 219,451 - Pending ones not inserted yet
QDFormerValues 58,726 - Revisions
QuakeDataDeleted 10,955 - Deletions (1 happened while I was getting this)
QDAlternates 1,909 - Ones where EMSC has a duplicate of the USGS one.
