Quake Watch 2010

reply to post by Mad dog

Quite possibly they are. But they are very erratic and, to me, seem to be agitated prior to a biggie in S.America. I'm also interested in that P.Rico is on the "locked" Caribbean plate at a very active juncture of many plate boundaries which is why I refer to it as a bell

The only problem with that theory is that the quake was at 45km, or 30km if you take what the Indonesians themselves reported.

My take on the 9th May 2010 quake is that it was an AFTERSHOCK of the Dec 26th 2004 9.0 Mag, it [the 7.2] was only 33 miles to the north.
The geologists down here in New Zealand have for some time considered that most of the large quakes in Fiordland area of NZ are connected each one a foreshck for the next , and bigger one, even if they are 3 years or 10 years apart, due to location., why not the same at Indonesia?

A 7.2 in Indonesia is usually no big deal, unless it is on land.

That last quake I reported yesterday has been upgraded from 4.04 to 4.455 and reported as felt on Great Barrier Island and Kawerau.

Felt Reports:
Reports of slight damage and a power outage on Simeulue island. Felt (V) at Banda Aceh. Widely felt in Indonesia. Also felt in Laos, Malaysia, Myanmar, Singapore and Thailand.

Tectonic Summary:
The northern Sumatra earthquake of May 9, 2010 occurred as a result of thrust faulting on or near the subduction interface plate boundary between the Australia-India and Sunda plates. At the location of this earthquake, the Australia and India Plates move north-northeast with respect to the Sunda plate at a velocity of approximately 60-65 mm/yr. On the basis of the currently available fault mechanism information and earthquake depth, it is likely that this earthquake occurred along the plate interface. The subduction zone surrounding the immediate region of this event slipped during the devastating Mw 9.1 earthquake of December 2004, and today's event appears to have occurred within the rupture zone of that earthquake. Today's earthquake is the latest in a sequence of large ruptures along the Sunda megathrust, including a M 7.8 in April of this year, approximately 200 km to the south of today's event; two M 7.4 earthquakes beneath Simeulue approximately 100 km to the south in 2002 and 2008; a M 8.6 210 km to the south in 2005; a M 7.5 650 km to the south near Padang in 2009; and two events of M8.5 and M7.9 approximately 1000 km to the south in 2007.

Those last two are interesting, thats 3 now way out on the Pacific Plate, out past the Hikurangi Trench, east of the Gisborne Knolls, approx. 136 km east of Gisborne, although the first one yesterday morning was a bit further north east even further out.
My take on this is the PPlate wants to move West but it is stuck right now, so buckles up back at where these quakes are at.
Could be a release of energy when the Plate does slide under Gisborne/ East Cape.
Then again maybe not

Thats what is so frustrating about quake watching.

You go girl!

You called it, and it's even a double.

Is it possible that this incident below:

is related to this?

Just posing the question. Thanks!

That's one of the other things I've noticed - P.Rico's do seem to come in pairs - another reason for the bell like ringing I associate with it. I wonder if this is something locked plates do - bit like a stuck pinball....

reply to post by Wookiep


Hmm, I like your thinking. I will have to check the location of both - although I haven't seen any reports of the quake being felt above-ground, as it were. Hmm....hmmm

Oh boy, just read the thread concerning the sink hole - that poor family.
