Quake Watch 2012

Why we should constantly watch the deformation of the seafloor

Scientists have yearned for years to plaster the seafloor around subduction zones with seismometers and every other kind of sensor imaginable.

The mind boggles really. Just what sort of probes might we be talking about?

Interesting stuff and curious after the discussions here that we should find this? No not really curious I suppose.

One important reason to plant submarine sensors is to watch the great Cascadia megathrust load in preparation for future subduction earthquakes. The locked and partly locked parts of the plate boundary, bound to break in our M9s, is shown in this figure (from Hyndman, PGC, 2012).

Russians have 7.2Ms for the main shock and 3 x 6 aftershocks

Hi Jerisa, your linkypoo is busted.

This works
'Earthquake swarm' shakes New Brunswick village

may continue to feel minor earthquakes for several more days or even weeks, according to a Natural Resources Canada seismologist.

ORLY? He can predict earthquakes can he? Or does he know something. Any fracking around here perhaps?

edit on 14/3/2012 by PuterMan because: (no reason given)

There has been test fracking going on all over the Province. It is a big issue here as most don't want it. The ones that do, are not informed of the dangers of fracking.

Marginally better on the IRIS Bud version:


All of the Japan seismos (well several) here

reply to post by PuterMan

yeah I had a look at IRIS, the red on top of the green confuses the first two quakes.
There was one IRIS MAJO channel that just showed the two bigger quakes (6.8mb, 6.4mb, Russian data), have closed it now though, so can't recall which one it was.
I'll have a look at the arrival times later, may clear things up.

Thats a handy page on QVS, , saves going through loading the IRIS Network onto GE and then opening QUAK query, for Japan anyway. Will use it next time.

Just in case you had lost this link. Live quakes

One going through now.

Are you, or anyone else who uses that site able to explain all the elements of it? Aside from the fact that I have to turn the sound down as it drives me demented what exactly is it displaying?

3.4 just popped off in the North Sea off Stavanger by the way. Probably not connected to the Great Glen.

OK...these are om the same fault line as the Argylle and Butte EQ's
This area had one on the 26th February which made the news

May be Puterman is right...when is he ever wrong maybe the Great Glenn is indeed seperating?

Sorry if this info is already available, but I think not..
Just wanted to report also that the quake activity in Azores (Portugal) has increased since 3rd March .. it was on Portuguese media. I know it is a well known area for it... but i think this should be also reported here ..

regards

This was a Felt one

See 4 posts above you!

2 reports both from the same location? Sounds like something local.

Their data is not so good. If you click the testimonies map you find several more along the coast of Norway.

Obviously EMSC is quicker

reply to post by PuterMan


It is a Strong Motion Seismograph. Not really sure about some of it. It will monitor from the stations flashing and give a reading of the quakes going through. The nasty sound is to warn you that a quake is happening. The higher the pitch the bigger the quake. It also measures quakes in other places if their stations pick it up. There usually is a guy there who speaks English as well as Japanese and tweets any larger quakes. It marks the place where the last quake was located, over 3 usually. Localised Gee really. I can't work out the colours though, depth? It's nied4maps test. I have been trying to get the software . It picked up the big quake. Horrible to watch,
Here is one from Utube. The pings are warning of a large quake. test
Sorry not that much help

That is a shame you posted the Mw on top of the mb. It would have been interesting to have both.


reply to post by Tzavros


Thanks, that helps a bit. Still hate that sound. Does my head in.

reply to post by Hellas


Could you now post the other one UNDER the 5.7 as it is interesting to see the changes in Lat / Lon / Depth if any as they recalculate.

Thanks


Excellent. There are differences. I thought there were. Different from USGS as well despite the same magnitude.

Thanks again.
