I just loved the maps in this paper. Here's a general seismicity map showing the Caribbean Plate acting as a big hot thumb over the American plate, which is a bit fatigued from its journey.
Ah, can't you hear the sea breezes now?
Of course, where there is plate subduction, there are volcanoes!
You can just feel that plate melting, and burbling up molten rock!
