Look at the TEC maps for today....a buzzin' up a storm down under


There was a lot more grey in that area early this morning.

I didn't get all of Japan NIED, I only saved from the 6.3ML onwards, it has moved to the 13-14th now.


Interesting Google maps won't show the Arctic Gakkel Ridge above Franz Josef Land
the quakes off the static map are the one Puterman posted here

Date/Time: 12/04/2013 10:15:09 UTC
Lat: 86.9867 Long: 57.2069
Magnitude: 4.4M/4.6 mb
Depth: 2 km
Location: NORTH OF FRANZ JOSEF LAND
Catalog Source: emsc, gfz and usgs
TTNT energy released: 119.7866

and this one from NORSAR

Date/Time: 12/04/2013 10:27:46 UTC
Lat: 86.02 Long: 67.83
Magnitude: 2.45 ML
No. of Stations:
Depth: 13.8 km
Location: NORTH OF FRANZ JOSEF LAND
Catalog Source: NORSAR
ID:
TTNT energy released: 0.0714

That NORSAR is hard work, I picked out the text file for what I thought was the 12th (day102) and edited all phase data lines out of it (many 100's of them) to get the single lines with the info I needed, put it onto Excel, 119 events, then I noticed the date ........... 12/04/2010 ................... arrrrrghhhhh
In the end I used the "last week" page with only 8 lines

Not something I could do on a daily basis, too much variance on the formats, I'll wait until Puterman gets those others in the loop

6.3ML,(5.7Mw), Awaji Island, Osaka Bay, Near S. Coast Of Western Honshu, Japan aftershocks at 27hrs
mag1= 154
mag2= 35
mag3= 10
mag4= 1
mag5= 0
mag6= 1
mag7= 0
total= 201
TTNT= 42,535.065

the map looks pretty much the same as it was at 5:11 hours afterwards, just denser, so rather than doing that again, here is something a bit different, this is the text file of the aftershocks up to 27hrs time elapsed.

New danger zone for large quake is now between the Sichuan and Yunnan zone in China .

Yesterday it was in the Banda sea area .

Seems to be very close to guessing were a large quake may happen.

The 14 Mhz area in light grey is the danger zone.




Idea came from this video

Response of the ionospheric electron density to different types of seismic events

Abstract. The electron density data recorded by the Langmuir Probe Instrument (ISL, Instrument Sonde de Langmuir) onboard the DEMETER satellite have been collected for nearly 4 yr (during 2006–2009) to perform a statistical analysis. During this time, more than 7000 earthquakes with a magnitude larger than or equal to 5.0 occurred all over the world. For the statistical studies, all these events have been divided into various categories on the basis of the seismic information, including Southern or Northern Hemisphere earthquakes, inland or sea earthquakes, earthquakes at different magnitude levels, earthquakes at different depth levels, isolated events and all events. To distinguish the pre-earthquake anomalies from the possible ionospheric anomalies related to the geomagnetic activity, the data were filtered with the Kp index. The statistical results obviously show that the electron density increases close to the epicentres both in the Northern and the Southern Hemisphere, but the position of the anomaly is slightly shifted to the north in the Northern Hemisphere and to the south in the Southern Hemisphere. The electron density related to both inland and sea earthquakes presents an anomaly approximately close to the epicentres, but the anomaly for sea earthquakes is more significant than for inland earthquakes. The intensity of the anomalies is enhanced when the magnitude increases and is reduced when the depth increases. A similar anomaly can also be seen in the statistical results concerning the isolated earthquakes. All these statistical results can help to better understand the preparation process of the earthquakes and their influence up to the ionospheric levels.

There was a lot more grey in that area early this morning.

Just to remind you that the area of TEC disturbance basically follows the area of maximum insolation and therefore rotates around the world in a 24 hour period.

Believe me I have downloaded the NASA/JPL TEC maps every 5 minutes 24/7 for over a year (I have stopped now with over 150,000 images under my belt cluttering up disk) and I can find absolutely no correlation at all between the maps and the incidence of earthquakes.

These maps are actually theoretical being the predicted TEC affecting communications and are just simply NOT sophisticated enough to detail what the scientists look at for TEC changes before an earthquake.

The details on these maps are actually taken from ground based GPS stations - you can find lots of details on how it works - however the ones the scientists use are satellite based. Not the same thing at all. (See the post above this about the Demeter satellite)

Don't mean to burst anyone's bubble but in my honest opinion these particular TEC maps are of no use to us in pre-determining earthquakes.

I still put a version of the TEC map in with my earthquake reports, but it is probably a waste of time.




ETA:

The most widely used instrument for ionospheric measurement is the ionosonde. The ionosonde is essentially a high frequency radar which sends short pulses of radio energy into the ionosphere. If the radio frequency is not too high, the pulses are reflected back to earth.

The ionosonde records the time delay between transmission and reception of the pulses. By varying the frequency of the pulses (typically 1-22MHz), a record is obtained of the time delay at different frequencies. This record is referred to as an ionogram.

I note that the Australian site refers to HF radar so maybe my comment that they use GPS stations is out of date? Don't really know and haven't the time to find out.

Basically what is does show is that these maps are based on GROUND BASED systems and not the same sa the satellites at all.

Thanks for that info!!

I haven't been able to access USGS IRIS maps since yesterday . It tells me FORBIDDEN. Not sure what that's about.

reply to post by ujustneverknow


What link are you using. Can you give an example?

I have had only intermittent Internet all day - some one burnt the cable in the bog I think. Wonderful!


Mm. Looks like an IRIS problem

Error:

error while generating plot java.io.FileNotFoundException: /budnas/bud/AK/BAL/BAL.AK..BHE.2013.104 (No such file or directory)

Can't get any seismograms in my program either so I am pretty sure that IRIS is broken.

Lamont-Doherty Earth Observatory (LDEO) is offline too
I see a pending gap in my records again, last download I did was 11th April
Hopefully they are shut down so they can install a searchable database

Oh, while I'm here, my China page for 2012 to 2013 has been reconfigured to include E. Russia-N.E Border Region
here


Good news is Chile search page is accessible again, I e-mailed them when it was broken down, but they never replied.


ha its back on now

From the Iris homepage, it looks like they had a power outage, and are doing a major system upgrade this morning.IRIS


It seems a few networks are not available in GEE right now, too. I can't get CI (California), or the PB (plate boundary) stations to load. Bummer...

ETA:
The Earthscope Transportable Array is currently moving to the U.S. east coast. So, there are new stations available on the TA network for folks to follow the shaking in the Southeast, and in a few weeks, the Northeast. They are currently installing in Virginia and working north.

map of station deployments

You can load stations in GEE, access station data here, or see a snapshot of the past 2 and 24 hours on these pages. (click around on the tabs at the top for different areas and amount of data shown)


Warning!
Do not be tempted to use the "earthquakes" tab from the last 2 links I gave above...it is preliminary data & has many false alarms and inaccurate quake locations listed.
Repeat---not reliable info. (the snapshot pages of TA stations at that link are fine)

reply to post by Olivine


Yeah! More toys, er, I mean tools!!!
Lots of info to wilf in!
Thanks, Olivine!

There will be a station only about 15 miles from me! (As the crow flies!)
The closest one I had found so far, I found a few months ago.
It's at a college about 35-40 miles from here.
Not that I'm expecting to see anything on it, I'm in PA!
Maybe some seismic testing/fracking traces!

I did see an archive link back to 2005, I think it was.
When I have more time, I want to look up the 5.8 in VA in Aug 2011.
That was my first real eq!

When I lived in Hawaii I thought I felt something, but it was just a very small,
short vibration, that I thought I felt when I was sitting with my back againt the wall!
Never found out if it really was something!

We have heard the Seneca Guns a few times here in the last 3 years,
so this will come in handy to see if anything ever shows up!!!
WOQ

reply to post by Olivine


Ah well, what the hell. I only just got back on line myself after being off most of the day. Seems the ISP has various problems still turning up as the result of people setting fire to the bog and burning/melting the cable from/to the main mast.

His words to them on Facebook were full of invective and completely out of character!!

I have to sat it: Is it me or is it quiet? I expected a barrage of quakes when I got back on and it hardly increased the list (M3.5+) at all.

It is nearly ready BTW Olivine. Will be in touch. (That was a secret message that should be ignored by everyone else )

reply to post by PuterMan


Sorry, just getting caught up!
Yes, the Great Salt Lake is really a lake.

www.utah.com...

Did the slide show up on the mine lists?
I was wondering...since there was a 5.1 & a 4.9, an hour & a half apart...
Looking at the picture, could the slide have gone half way down to the midlevel.
Then when that was finished & enough weight /pressure built up,
it let loose again & finished sliding all the way to the bottom of the pit?

www.deseretnews.com...

It was funny that they only mentioned one slide!
WOQ

No one worried too about the series of recent Oklahoma shakers???

Felt by anyone?

Leading up to anything I wonder...

Apologies if anyone has posted this already - don't have time to look back

Earthquake activity east of Grímsey has decreased

Not yet. Seems to be stuck on 11th March. The list are ROUTINE mining seismicity so it may not get on the list as it could hardly be called routine!

There were three slides if you look at the seismogram.
