Quake Watch 2010

You are doing a great job in informing us on current earthquake, I wanted to thank you. This is my fav thread here on ATS.

If you have an Iphone or Ipod touch that is jailbroken, there is a great app that shows in real time (USGS) USA and (INGV) ITA earthquakes.

Earthquake.sid


Keep up the good work !

Hello,

Seems USGS doesnt show results from some regions of europe. I say this because in the last 5 days, south of Portugal (where one fault exists) suffered one 4.1 (saturday) and one 4.2 (today) quakes. There wasnt deads or material damage, but still its not quite normal here to have 2 earthquakes in less than a week, not even talking in 4.0+ ones.

I hope this is not sign of a bigger one to come, not unlike the one from 1755. Right after the HAITI one, on a tv show, a guy talked about how the 1755 one ocurred not far from one in HAITI at the time.

Thanks indeed for that information. I believe I am correct in saying that for some networks the cut-off that USGS uses is actually 4.5 Mag so these would have just fallen below it.

As a matter of interest there are at least 3 stations with real time data in the University of Lisbon network [LX] and 5 others in the Portuguese National Seismic network [PM]. All of these will produce a plot using the Webicoder plot retrieval system in Quake Data, or manually extracting using Quackery.

As an example GGNV.LX..BHZ.2010.089 (Yesterday)

or GGNV.LX..BHZ.2010.090 (Today)

Hi earthquakers, I have a question about the amount of earthquakes on the USGS map.

The map shows earthquake activity in the past week, right up to the last hour, and Iv`e been looking at it everyday pretty much since the Haiti earthquake, and it appears that there is usually around 260-290 (ish) quakes at any one time on the map.

Now, Iv`e noticed this number dropping to 169 (today at 17:11 UTC).
I started noticing this drop a few days ago, and it has steadily decreased.

My question is, is this a known phenomenon, i,e after a couple of biggies and their respective aftershocks, do the number of quakes fall once everything has calmed, or could this possibly be a "calm before the storm" type of thing, like, could the fall in numbers indicate a possible big quake coming soon?

Forgive my tectonic ignorance if this is a silly question, it`s just a question that came to me as I noticed the quakes depleting in number recently.


Thanks in advance,

Namaste

Sorry to be a pain, but can someone who may know the answer to this help me out please?

Obviously after Haiti, and particularly after Chile there were more than the usual number of earthquakes world wide. I would venture to suggest that if you have been watching since Haiti then what you are possibly seeing is a return to 'normal'.

In theory after an earthquake of magnitude, and it's associated aftershocks, the stress on an area should have been relieved (not always the case) and thus you might expect the number of quake to diminish.

This in fact is what we are seeing in Chile at present I believe.

Overall I would not say that the number of quakes world wide is notably different from 'normal'.

I find RSOE reports more details on European quakes

USGS also doesn't always report quakes here in New Zealand, for that check:

Here is a link giving averages per year for quakes.

IMO things seem quiet and odd.

Also In said link They state:

Starting in January 2009, the USGS National Earthquake Information Center no longer locates earthquakes smaller than magnitude 4.5 outside the United States, unless we receive specific information that the earthquake was felt or caused damage.

reply to post by Anmarie96


Yup, pretty much what I said.

Yous all might be interested in this (I think that is the Anglicised Gaelic which has become y'all in the US)

With regard to the failure of instruments in the Yellowstone Park this is apparently due to a relay problem outside the Park and we have to live with it for the time being. They are working on it, but there is no resolution date at present, however you may rest assured that the YVO is happy that there are sufficient instruments operational not to cause them any problems.

They will still be able to tell us if she is going to blow!

reply to post by PuterMan


Sorry, I did not mean to repeat you, I just posted Their direct words.

(I think that is the Anglicised Gaelic which has become y'all in the US)

Is this a good thing or a bad thing? I don't know what it means

As for the instruments and the relay problem - I am sorry, but I don't buy it. Sorry. and - YVO has sufficient instruments operational? - Ok, how's about They share that!!

Wait should this be posted in Yellowstone or here - idk guess it applies both places.

reply to post by Anmarie96


Don't forget that a relay problem outside the Park does not mean they can get data 'manually' as the instruments are still working. I would imagine they must have some means of doing that.

Eh?

Is this a good thing or a bad thing? I don't know what it means

- All of you

Addendum: First let me say that this NOT intended to be at any of you! As a pure matter of interest, with an element of concern, I wanted to see what is available in the Park. On the list below I can get plots from anything that is white. Red is not producing anything and purple/lilac/mauve (whatever you call it) is not tried as it is outside the Park. (There were a few I tried outside but I have not included them.)

I leave it to you to decide if you consider this to be sufficient.

None of the plots I checked were more than 3 minutes old, and most were within one minute.

Am I imagining things or have USGS snuck in a couple of Antartica 5 pointers, they are shown as yellow being both over a day and an hour old but as a regular watcher of the global usgs page i don't recall seeing those two ?

reply to post by PuterMan


Did you mention Lilac - Oh, I can't wait for them to bloom here - the smell - hummm. Ok, anyway before I get lost in that - This does raise question as to why you can pick these up (which of course is because you are a computer genius). So, the question is - if you can pick up and They are picking them up - why are Their sites down ? What you are picking up is not what they are making readily available for us let through Their sites -- guess we just need your software - or for some of us, learn how to use it :-).

They (Pacific/Antarctic Ridge and Macquarie Islands) were both reported at the time - I remember updating them on my Quake group page.

The question is what are you referring to as their sites? If you mean GEE then I can't comment as I never use it. These plots are straight forward downloads from IRIS, I just happen to use QuakeData to do it as it is so much faster and easier.

What I do find a bit strange is that one would assume that all this data is going into IRIS since that is the source of the BUD Explorer/Quackery plots. I think that GEE also uses the IRIS data. Certainly Vase does. I might see if I can get some of the ones you say are dead on Vase.

Edit: I just looked at the WY network and put in for data from all stations beginning with Y. The list below is the the return of all stations that have current data in the past 3 hours.
