I'm just coming up with an idea.
Historically, (admittedly way prehistorically) you have the Deccan traps rather close by. You can't really disregard volcanic activity as having a lot to do with earthquake activity. One reason for quakes would be upwellings of magma from hot spots in the crust, releasing pressure would trigger eruptions which would trigger quakes and so on. I'm not saying it right. You can't really separate them. It all goes back to the old "the gods are angry". I suppose I could wander over to the local university (U of South Florida) and see if they had anyone wandering the halls with a clue. That's a good 30 mile trip by city bus, since I'm not allowed to drive on these stinking pills the docs have me on.
