Yemen Seismological Centre in Arabic - Correction, you can select English

I recall that site from a few years back, there was a pretty major swarm actaully in the Afar area, on land.
But since I've never been able to find it again, all the links from EMSC come back "not available".
I tried your link and got there, but everything I hovered over onthe page came back with the message

"An error has occurred in this dialog.

Error: 1

The crust is spreading apart.
Read back a few pages my friend

2 more since you posted that, whats the score now ..................... 45
MAP 5.0 2010/11/16 02:07:04 12.466 44.259 11.0 NEAR THE COAST OF YEMEN
MAP 4.8 2010/11/16 02:05:21 11.989 43.932 8.6 NEAR THE COAST OF DJIBOUTI

I bet theres more on EMSC, but I find it hard to copy and paste their lists.

Have any of you noticed that the largest plate under the Pacific Ocean (the Pacific Plate) seems to be very active and may even be rotating?

Also interesting to learn that there are an increase in undersea volcanoes.

Around which 'pole' is it rotating?
Is there just one 'pole' about which it is rotating?
These are serious questions.

We had another earlier - a mag 4.0 - certainly felt in this household (was quite close to us!).

Hey guys, I'd appreciate some feed back on this:

It indeed looks like it is twisting/rotating, and now, that pressure is affecting the Arabian plate! Just LOOK at the 3 mini-swarms of quakes --- at the tip of each corner of the Arabian plate! It's amazing to see!!

IMO, I have a feeling, we'll be seeing scientific papers on this years activity with increased plate movement per year---more movement than other years in the past.

Africa is next. It's already showing some small quakes.. nothing worth reporting though.

BTW: This type of energy and movement we're seeing on the Arabian Plate is exactly what destroyed Alexandria in Egypt. (With a Tsunami after the quake too). I sure hope we don't see an 8.0 pop off in the Med.....

Somewhere I said 7.5 to 8 in Greece during Jan/Feb.

I must look up the post.

Can someone please decipher this bump? I still don't know how to read these things;



I couldn't find it on geoscience but that's because they are so slow at updating their info.

Is it a quake or those damn miners?

This at CTAO (Almost the same thing)


OK the first one is the 5.1 at Santa Cruz islands

Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2010-11-17T13:39:24.000Z,-12.16660,165.90610,5.1000,40.0000,Santa Cruz Islands

Here it is at CTAO in the phase data
CTAO eP 13:43:59.07 0.3 20.4 245 b:2.0+2 2.0 5.1 CTAO

The second is this one I think:

Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2010-11-17T15:53:30.000Z,-7.93130,129.44240,5.9000,13.6000,Kepulauan Babar. Indonesia

Here it is arriving in the phase data
CTAO eP 15:58:06.49 0.5 20.3 128 b:2.4+2 .90 5.5 CTAO

------------------------------------



For MBWA that you showed:
KEPULAUAN BABAR, INDONESIA
MBWA ePn 15:57:13.76 -3.6 16.1 215 b:4.3+2 1.2 5.5 MBWA

SANTA CRUZ ISLANDS
MBWA eP 13:47:35.63 -0.8 45.0 252 b:1.7+1 .95 4.9 MBWA

Note there is very little difference between the times for the Indonesian one but a much bigger difference for the Santa Cruz one. Without looking at these two stations on the map I would guess that MBWA is slightly to the north of and considerably to the west of CTAO.

Edit: Well my guess was nearly right. MBWA is slightly south of CTAO but MWBA was closer to the quake epicentre. 1798 Km against 2239.

Where the heck is TA -

Ok, thanks. they just seeme like big bumps for events that happened so far away. It's amazing really. The instruments must be very sensitive?
So in order to figure that out, did you just check for quakes that coincided with those times? Are there instances where quakes of that magnitude don't show up at such distances and would that be due to their relation to a particular plate?

reply to post by zenius


What I usually do is look for what I perceive to be the start of the quake which is usually just before the big squiggle and then go to my list of quakes and find one that happened of a large enough magnitude just before that time. Once I have identified on then I look at the station name and go and find that in the phase data. That will confirm the start point on the heli. I don't usually pick a station, but I might if I am not sure. This usually only happens when there is a bigger one which rings all the recorders and you can then track it back.

With a big one it is not always easy to determine fro the LISS display exactly which one is closest.

You can also corroborate by looking at the Theoretical P-Wave Travel Times to get a visual fix on the sort of time the P wave should have arrived.

Take for instance the 5.1 @ Banda Sea this morning 5:05 UTC (Actually that is the EMSC mag. USGS have it a s a 4.9)



Not so easy to spot the start of this one. You can see your other ones still on it. The text on the image is from the USGS Phase data

Edit:

Are there instances where quakes of that magnitude don't show up at such distances and would that be due to their relation to a particular plate?

If you take the 5.1/4.9 Banda Sea that showed much smaller than the 5.1 Santa Cruz Islands even though there was not a huge difference in energy. Santa Cruz Islands are on the Oz plate but the Banda Sea has another plate junction between it and Oz so yes I guess that is probably the reason - along with the intervening geology.

Now I have to learn how to understand phase data? Too much to learn, not enough hours in the day!
