At what depth do most earthquakes occur?

A really deep one... I'm pretty sure this was obvious.
jk less thank 80 km or 50 miles from the Earths surface

Most earthquakes occur at depths of less than 80 km (50 miles) from the Earth's surface. The San Andreas fault is NOT a single, continuous fault, but rather is actually a fault zone made up of many segments.

Migration people get up and go cause they feel it is best for them
