Re: Eastern Caribbean seismic activity
I wonder if anyone ever feels these? I never see anyone say anything about them except to post the reports.

The vast majority of them are small quakes that people have not felt in the region.But some of the stronger ones have been gelt including myself.The last one that I felt was on Christmas eve night,that was a 5.1 quake.

Saw this interesting blog on the latest swarm NW of PR

MODERATE EARTHQUAKES SHAKE ANCHORAGE, ALASKA AND DOMINICAN REPUBLIC
EARTHQUAKE SUMMARY FOR JULY 28, 2011
A moderate earthquake of M 4.6 was preceded by a foreshock of M 4.0 in the Dominican Republic area today.
Two earthquakes of larger magnitude have hit the region in the past year - an M 5.4 on March 16, 2011 and an M 5.5 four months earlier on November 13, 2010.
The four month interval between these events was continued with today's earthquake.
We believe this epicenter is near the likely rupture point of the coming great earthquake on the Puerto Rico Trench.
This event could occur this year, most likely in connection with a strong retroactive moving hurricane and a strong geomagnetic storm.
Such an event would likely trigger a major tsunami which could cause considerable destruction in the northern Caribbean and possibly along the U.S. Gulf Coast region.
Today's activity occurs following the passage of Tropical Storm Don through the region two days ago.
At the time we suggested the possibility of such a series of earthquakes associated with this tropical storm as follows.

Here is a report from our friend of St Lucia: Chritopher Jenkins

Well, the weather is ok but just as I was thinking of drifting off to sleep, we had an earthquake - 5.1, small beer maybe but the strongest here for a while. It was actually off island, maybe 40 miles away but not too deep so strong enough for us to shake, rattle and roll. Reactions range from slight to strong on the MMI scale - 3 to 5.
