Quake Watch 2012

reply to post by pasiphae

you may find this page helpful earthquake.usgs.gov...

of course USGS tend to downgrade 6's to below that 6.0 mark, so the mag. 6 figures may be skewed low.
5.5 is a good number to start "strong" quakes counts, as that encompasses the USGS's 5.9's
on the chart they have 58 6's so far this year, of course anything could happen in the 2nd half of 2012 but so far thats a low figure similar to pre 2003 figures.

I rather like the map with it's depths display

*(not directed at you as the messanger, just a comment)
and that is why USGS are becoming a waste of time
mb for the first and the other in Mw
what use is that to anyone?
Geofon is the same

try both in Mw (LDEO)
2012 6 11 5 2 16.0 36.25 69.75 33.0 5.2 HINDU KUSH REGION, AFGHANISTAN
2012 6 11 5 29 20.0 36.50 69.50 33.0 5.7 HINDU KUSH REGION, AFGHANISTAN

or both in mb

with USGS you have to dig 3 pages in, to find the 2nd one was;
mb = 5.6 (108)

(the Mw been upgraded 0.1 magnitude since you posted

Still pretty quiet in NZ
4.5 yesterday near Whakatane seamount 215km deep
4.2 this morning ChCh
seems geonet may be short staffed or are struggling to locate the earthquakes, big jump in the Ref ID numbers in the last 2 entries in the download data

thats 439 possible events overnight

os Mulga, Turkey 6.0ML, 6.1Mw aftershocks interactive map, 64 of, according to Bogazici University Kandilli Observatory and Earthquake Research Institute data

and same from National Observatory of Athens only 29 a/s of their estimated 5.8ML main shock.


and EMSC (my file)
estimated 6.0Mw afteshocks , 129 of

interesting discovery,
I downloaded the EMSC KML file directly, then I took the data off the search for earthquakes page, and created my own KML file and noticed the location icons on Google Earth were in different places !
What it is is that on the EMSC list page, and on the popup tags the co-ordinates are only 2 decimal points, but in the actual data they use to create the KML the co-ordinates are to 4 decimal points.
Hense using the list data you get a grid like layout ( 2 decimal points) but on the KML they are all over the place, (more accurate to 4 decimal points)

This has been discussed here on Quake Watch before, and we know the 2 decimal point thingy causes a grid pattern, but its good to know they do do a more accurate version.

Heres the EMSC's own version (circles)combined with mine (coloured orbs) put together so you can see what I mean

I had to go out, too late to edit now.
Disregard the source on the My EMSC map popup windows I forgot to change the parameters on the GPS visualiser program from KOERI to EMSC. I'll change it now, but the links here on ATS might not change.
If you can't find my EMSC 6.0, it underneath a green icon @ 2.1-10/06/2012 17:00, same location, thats another pitfall of only having 2 decimal points, the latest quake covers the previous one/ones at the same spot. You have to click on the text list in the left hand column to find it.
Corrected results will be on eqarchives.wordpress.com... when I'm done. [

KOERI had 162 aftershocks at last time I counted, been more since
I had a better page for data that I had forgotten about,
www.koeri.boun.edu.tr...

my page on it - Ölüdeniz Açiklari-Muğla, Turkey 6.0 Aftershocks

I can't be bothered with EMSC until they go to 4 decimal points and put the co-ords into decimals instead of that N, S, W, E, BS

i figured i would ask the resident quake guru's about this site and the apparent New Madrid increasing activity?

anf.ucsd.edu...

seems like it's really picking up to me, but i'm not highly knowledgeable in this field.

Hello LittleBlackEagle. The software on the page you linked reports lots of false alarms, or has locations 100's of kms away from actual earthquake epicenters. We shouldn't use it.
(I stumbled upon that site 6 months ago and caused a minor panic before the more knowledgeable folks on here steered me straight)
If you're interested in New Madrid, this CERI page has timely, accurate information.

Yesterday AP sent a news with 100 deaths estimated, today Reuters sends 80.

Afghans fear 80 dead after quake triggers landslide

KUNDUZ, Afghanistan (Reuters) - An earthquake in Afghanistan triggered a landslide which buried mud homes in a mountain village and rescuers feared at least 80 people had been killed, provincial officials said on Tuesday,

Two quakes with magnitudes of 5.4 and 5.7 struck mountainous northern Afghanistan on Monday, bringing a slide of mud and rocks down on the remote settlement.

thanks for the heads up amigo. i will be keeping an eye on that page you linked me to.

seems though new madrid is getting quite active, even from what CERI has to report.

"moderate" quake south Kermadec Islands 2012/06/12 13:48:41.4 UTC
LDEO = 5.4Mw
GFZ = 5.4M
EMSC = 5.2mb
RAS = 5.1mb
USGS = 5.1mb, 5.6ML

I'm Grumpy.

IRIS DMC real time streams still down, after all these hours. That's unusual for them to be out this long, and it could potentially delay data to some scientists in the event of a big quake emergency. But instruments are still delivering data, so for the most part, scientists local to an event will still have access to data through local internal networks.

The general public can still see webicorder data for a station through the IRIS BUD explorer, if they must. But forget GEE until IRIS eventDC comes back on line.

I was just about to post this--It is odd. Seems to be located just NE of Katmai volcano, but look at the depths: 211km, 117km, 40km....Yet the 1st Mag 2.5 listed was very near the surface at 1.3km depth. Weird

Indeed, Olivine, here's a picture of how spread out they are.



I do hope that nothing big spawns from this, but I would be on alert.

I have seen a definite difference in earthquake patters since the Italy quakes. Anybody else seen the change.
