Looks like the aftershocks of the M6.4 north of Puerto Rico calmed down and there is a new swarm west of there, north of the Mona Passage between Puerto Rico and Dominican Republic. We have been watching these swarms north of Puerto Rico and the Virgin Islands and usually nothing big follows (the 6.4 would be an exception). But, it is an (oblique) subduction zone so I think capable of M8 quakes.
