I'm only glancing through the 7 day list, but the last couple of days some of the quakes in this swarm are over M4, and one of the last ones is M5.2.
Beth, I don't know what this means, but there have been swarms for at least the last few years north of Puerto Rico through Virgin Islands, and nothing comes of them. But I'd be very interested in some detailed studies of these. For example, is daily energy release in the current swarm increasing?
