Some Seismic Activity in the Eastern Antilles

Some of that seismic activity in the Eastern Antilles is centered off the Mona Passage between the Domincan Republic and Puerto Rico. Generally we have seen earthquakes in the 2.0 to 3.3 range in recent months but in the last twenty four hours we had a 4.0 in eastern Dominican Republic and a 4.6 slightly north of the Mona Passage, as well as, a cluster of at least ten smaller ones. If things quiet down for a day, a larger one seems to burst forth as energy is bottled up somewhere deep in the earth. Again, I will take a multitude of small quakes than that sudden burst of energy that can really wreck havoc.
