A major earthquake - magnitude 5.4 on the Richter scale - was recorded today at 0840, learn a communiqué of the Observatory. The epicenter of this earthquake of tectonic origin was located 64 km to the southwest of Saint-Barthélémy, 159 km depth. This earthquake, given its depth reached only (rarely felt) intensity of II, or III (weakly felt).
This event follows on two other earthquakes occurred recently in the same area. January 20, an important earthquake of magnitude 5 on Richter scale of tectonic origin, had been registered at 23 h 37. Its epicentre was located 72 km south of Saint-Barthélemy, 150 km depth. Previously, January 5, a low 3.6 on the Richter scale magnitude earthquake was recorded at 5 h 53.

There was a 5.4 quake between the Dominican Republic and Puerto Rico.There are no reports of damage nor Tsunami.

[Gustywind]

Another one?! hope that it's not a sign of things to come.

[cycloneye]

And yet,another quake this evening,a 3.8,that I felt.

[Macrocane]

Pretty active days in the Caribbean plate, a couple of days ago it was in the subduction zone between it and the Cocos plate and now in the Eastern Caribbean. Hopefully they are only normal events and not foreshocks.

[cycloneye]

And yet,another quake,this one in the Sombrero fault in the Virgin Islands.It was a 3.9 one.

[cycloneye]

For the peeps who may not know this,the Puerto Rico/Virgin islands and Leewards is one of the most active areas of seismic activity around the world.Fortunally,most of the quakes are small,but also many have been moderate to sometimes strong.There is the Puerto Rican Trench just north of PR where the deepest part of the Atlantic is,there is the Mona channel fault and there is the Sombrero fault in the Virgin islands area.

Seismic activity since 1990 to present.

Below you can see the many small quakes that occured in the overnight hours of April 5th But only a few of those were felt by people.
