Humboldt fault
A fault is a fracture in the crust of the earth along which rocks on one side have moved relative to those on the other side. Most faults are the result of repeated displacements over a long period of time. A fault trace is the line on the earth's surface defining the fault. Surface rupture occurs when movement on a fault deep within the earth ...Humboldt County, CA has a very high earthquake risk, with a total of 3,422 earthquakes since 1931.
