British Virgin Islands - EARTHQUAKE swarm...when CALIFORNIA Starts Virgin Island stops..definite correlation

Thanks for that info....It really does make interesting reading- there have been quite a few devastating quakes in the region havent there....and tsunamis as well. Not a good history.

I thought perhaps I may find some historical info relating quake swarms to a large event in the region...but I cant find any quake swarms in the region prior to this latest one....so anything possible with this scenario.

I have noticed a pattern here in NZ...we have a spot off East Cape that has swarms ....Not quite as many quakes as that but in a very similar spot by a subducting plate. Over history the swarms have often stopped after a much larger quake that has followed the swarm...but normally further up the plate from where the swarm occurs. If the same thing were to occur at British VIrgin Islands the corresponding area at risk would be Cuba.....

But like I keep saying...there is no precedent for this from what I can find...

Thanks for the research you have put in about these swarms. I have been watching the one off the East Coast and the maps you have put up of the British Virgin Islands really helps me picture how things are going over there.

One of the concerns in this area is that a quake will cause part of the trench to collapse in to the depth of the Puerto Rican Trench, displacing a large volume of material causing a tsunami to hit the north coast with practically no warning.

More popping up:


A 2.9, a 3.1, another 2.9 and a 3.0...

4.4 in Costa Rica and a 4.8 on the Mid-Atlantic Ridge

I live in Nosara, Costa Rica. After the 7.6 it's non stop aftershocks 4.3 last night (which felt like a previous 5.6) and a 4.4 this morning. Probably will have them for quite some time. here is an average day (as of now) on this side of the Caribbean plate. This added to El Salvador's recent 7.6 make this side a really shaky place.

Would these have anything to do with that side by the VI? It's part of the same plate right? Excuse my ignorance but after this last month life has revolved around learning about earthquakes.

I'm so glad someone else is finally watching this swarm!

The Virgin Island swarm started up when the Brawley swarm started. While Brawley quieted done - this one hasn't.

During the Brawley swarm, I noticed a slight pattern. If Brawley had a quake over 3.0, then the Virgin Islands countered with a similar size, although usually larger, quake between 17 and 30 minutes. Or it was the other way round...hard to tell which came first.

I knew then that VI was the place to be watching and Brawley was just the side show. ::nods::
