Looks like there have been more M3+ quakes around Puerto Rico and the Virgin Islands the last 24 hours than what has been usual for the last weeks or months. Many of these are deep: 50 km in the north, 100 to 121 km in the south, which is the dip direction of the subduction zone.
We've been commenting here on swarms in this area, on Earthwaves, for at least a decade. The ones in the last 24 hours may be a bit different because they are really spread out over a large area (which has occurred before) and because they seems to define a S-deepening zone (don't know whether this was the case on any of the earlier ones we noticed). I don't think any of the other swarms in the last decade led to a major quake.
