I am from an unstable tectonic area, and I have been reading up on earthquakes for a presentation I will make in a week.

In a typical year, one million earthquakes occur worldwide that are big enough to be felt by people. Most of them are small stuff. magnitude 3 or smaller.

Just business as usual within the Ring of Fire (the Pacific Rim, earthquake and volcano factory for the world).

In southern California yesterday we had five (mag 2.7 to 4.1) and we have already had two today. These are centered near Coso Junction, about 140 miles away, so none of my teacups have rattled yet.
