New warning on earthquake in Himalayan region

Pressure in the region’s crust is building up and could be released far more powerfully than previously imagined, the researchers warn

Bhargavi Kerur & Jacob P. Koshy

Bangalore/New Delhi: North India could experience a powerful earthquake, it could happen sooner than expected and wreak more damage than previously estimated, according to the findings of a research study by scientists at Bangalore’s respected Indian Institute of Science (IISc).

India is nowhere close to being ready to deal with a powerful seismic shock, according to an official at the National Disaster Management Authority (NDMA).

The researchers analysed earthquakes over the years in the seismically-volatile northern Himalayan region. Their study will be published in next month’s issue of the Journal of Tectonophysics, a peer-reviewed journal.

For at least three decades now, seismologists have been unanimous that a major quake (exceeding magnitude 8.2) is imminent somewhere between Bihar and Nepal, and Kangra (Himachal Pradesh), referred to as the central conflict zone, as well as around Delhi and Uttarkashi. The IISc scientists point out that those studies assume that the last major quake that rocked the region happened 500 years ago, whereas their calculations and on-site excavations suggest that such a quake happened 1,000 years ago.

Weird, eh? But they have had eq's in the past. Here is a link to to a USGS history summary for MN.

is it me? or is the Vanuatu region getting ready for big one? seen here earthquake.usgs.gov... and then what about the CA/NV region? is it building up as well?? This is just a thought, what if the hot zone is moving east?

A big one could happen any time in the Vanuatu Region, but this just looks like a Swarm, the magnitudes are all in the low 5's.
Just had a quick look through the Networks that cover the area
usgs has 6
emsc 5
gsras 5
geofon 3
ga 0
the aussies (ga) are the closest, they must be tired and sleeping in after the big wedding

maybe, but I think the next Major quake Globally will be in China (because of the Japan 9.0)

Hope its not today, I have enough on my plate plotting the Vanuatu Swarm

OK this isn't unreal but it is very rare. We had an earthquake this morning measuring 2.5(i know very minute) but none the less it was an earthquake. i have only known of one other quake in MN that happened near or in Minneapolis . just thought i would post this one as it is happening around this weird time we are having on this rock right now.


Peace.

Just a small one early yesterday, but only 17.53km from my house. Didn't feel it.Shallow for the Wairau Fault, usually the quakes are at 50km depths

I wondered if you felt it (surely). Not much of a shake here in the City, seeing as it was in the Lees Valley area, but the dogs did respond in their usual manners (barking, hiding, whining). Hope you're o.k.

Keep an eye on Eyrewell Forest. There have been quite a few in that area.

Friend in Springfield has damage. Funnily enough after the few 3's we'd had there recently I had thought we might get a bigger one - stress transfer to the west end? Or.. is it Greendale at all - that 5.2 was up nearer the Porter Pass fault isn't it?

I've got it between Black Hill and the Townsend River, just north of the Townsend Fault.

Not lately that I noticed, but do you think there is a relevance of that location to a change in where the Greendale Fault is trending


There was that Swarm there just the day before the 6.3

There was a 3.1 a hundred km off Kaikoura just a bit over an hour prior to the 5.2, thats the 2nd time I have seen one out there, adding more weight to the theory that the PP Tectonic Plate margin has moved south from Marlborough

This is making me very nervous. Are we gearing up for a major quake? Had one of those headaches yesterday -

Geez the 29th mag 5+ was amess, took me ages to sort out the list, 26 individual quakes


I think I got it right
Last 7 days 5+

I've been sorting them by UTC time, but some of the times didn't match up between Networks, one usgs quake was 3 hours after the others had it, I'm presuming it was the same quake.
5.3, 2011/04/29 13:12:46, 21.2, 122.02, 186, Taiwan Region, emsc

5.5, 2011/04/29 16:00:41, 21.182, 121.9798, 176.7, Taiwan region, usgs

and quakes with the same time but different locations didn't help

another one where usgs are half an hour later, I'm not sure these are the same quake?

5, 2011/04/29 08:56:48, -19.2328, 167.7221, 24.4, Vanuatu region, usgs

I hope I have the times right on my Excel file, usgs still giving me problems converting from text to time, all the other Networks convert to am/pm in the column, except usgs

The New Hebrides Trench (Vanuatu) was a real mess

The Russians with their 5.1 for Taiwan look off the mark
5.1, 2011/04/24 22:53:37, 21.08, 121.41, 33, Taiwan region, gsras

I would have said from the USGS phase data that it was actually less than the 4.9 they have it at. They seem to have a knack of just lowering things enough normally to 'miss' a next bracket!

Hmmm, something went wrong at my end then.
I'll check it out later today when I do the 30th.
that 16:0041 looks out of place
I may have mucked up the rows when I transfered from my usgs file to the compliation file.
I have a file for each Network

I was just wondering, in the following Mt.St. Helens Seismogram, HERE

if the odd activity signatures could be caused by possible solar flares?Solar disturbances involving the atmosphere?

Also, noticed on Intellicast that the earthquake detection is only showing up with red dots? Usually there is multiple colors representing different times/magnitudes.

Keep Up The Good Work Quake_Watchers!+!
