Quake Watch 2010

Yes, and away from the City - my hubby is at work in the city and rang to check I was okay as was felt a lot stronger there than here. Even here (50km away) it was felt strongly. Although I had smaller one closer to me about an hour later that felt huge - I hit the floor by sofa and dogs reacted.

A 3.9... in Austria ???

That's not a location you see very much on USGS

My home .. !!

I did not feel it. But it was very close to my location.

This is just a foreshock, a stronger following. 4.5 or 5 +. I hope I am wrong. : (

And so it goes on .... this morning has already been busy with aftershocks...

AND, I notice that the USGS have started reporting them - even as low as 4.0 ... why? Should I be worried now that the USGS seem interested in our wee Island? What do they know that we don't (perhaps the location of the hidden deep thrust fault?!!)

The aftershocks must be hard on your nerves - certainly hope you don't get any large ones.

Tonga's acting up now with two 5+ quakes back to back today, and a total of four 5+ in just the last week right in the same area. That's not looking good. Foreshocks?

Hmm, Tonga's a pretty active place.. not unusual to see 5's there... worth keeping an eye on though.

@Berkeleygal: - Many happy ones

@AnneMarie: - "Did you try and reboot your computer" - Ooh you little help desk person you. When in doubt - tell the punter to re-boot!!!

@Mr Lee:
Not seeing any significant increase in Hawaiian quakes so far. Cumulative for Hawaii shows very steady quake incidence.



Could you also explain how this would work? It would seem that in order to fill the caldera something between 2 to 3 cubic km of material would have to flow (not impossible of course) and somehow it would appear to have to defy gravity. Unless I am reading this wrong it would seem that the topography would direct any lava overspill towards the west or south. The elevation to the North-East is considerably higher than the South-West it would seem - but I am only reading this off Google Earth and I would of course bow to local knowledge.

@Moorfnz: Tonga - Hummm? Need to look at this again in a day or two to see if we have a trend.



Edit: Just for good measure here is the global 5+ graph from 01 July 2010 to today.



The steady rise on this graph may indicate that the slight increase a Tonga is being balanced by fewer somewhere else.


And the identical period in 2009

You beat me to it!

That's quite some activity going on down there!

nods

and i am watching Cloverfield on TV, i'm already jumpy

I see that largest Gulf of California has been downgraded to 5.7Mw
earthquake.usgs.gov...

and the Austriain quake yesterday was given a 4.1 by Geofon, manually revised up from 4.0.
Some pretty big ML readings in the phase arrival data. 5.0ML, 6.0ML, 6.2Ml, 6.6ML from French stations

yeah, looks like the gulf of cali is getting pounded. If you'll notice the phase data of that last one:

neic.usgs.gov...

you'll see that station IU.SLBS is missing, but it's there on the others. We lost it a while back- in fact, it appears most of the IU network is currently down. IU.SLBS was perfect for monitoring these quakes. Even the USGS can't do anything about it immediately....

I think a bigger one is around the bend. But I have to go to bed, hopefully for a peaceful nights sleep.

things are surely picking up

I don't post on here too often, at least not for a while, but I'm reading quake watch everyday & mentioned to my partner this arvo (it's 7pm here) that I think Cali is in for a big one soon - just a random feeling from watching the last couple come in. Really hoping they aren't foreshocks!

Are these considered aftershocks from the Baja 7.2 back in April?

Not sure what the radius is for the fault it occurred on.

Looking at the magnitude and cumulative for the Gulf of California only there does not seem to be a massive increase, but that does not tell the whole story. I have not bothered with those graphs because this one - energy released - is the

[atsimg]http://files.abovetopsecret.com/images/member/b2a12300b1f0.png[/atsimg]

This is showing a massive energy release increase in October and bear in mind that this is over 2 days in October this year only - the 13th and 20th.

On these two days to 20th has the major share of it and we are only at quakes to 07:40 UTC so far.

Total of October 1062.445482 Mega thingys
20th October     1062.245267 Mega thingys

As you can see the 20th has produced virtually the whole of the Oct 2010 energy release.

I think probably not (if talking about the quakes in the gulf of California this month)

I think they have a life of their own apart from Baja.
