Per Stales' and Consuelo's comments, the entire Pacific is known as The Ring of Fire to geologists and vulcanologists, since it seems that the volcanoes that one finds on both sides of the Pacific (now THERE'S a misnomer!) indicate where the fractures in the plates are. We here in Oregon had a shake of equivalent magnitude (but no magma-tude!) last year, and, of course there was Mt Saint Helens in 1980. I heard quite a bang from that, and I then lived over 200 Km away.

As for noun/verbs, probate is a bit of a stretch, but it's too early here to think.
