Northridge Blind Thrust Fault
The Northridge Blind Thrust Fault (also known as the Pico Thrust Fault) is a thrust fault that is located in the San Fernando Valley area of Los Angeles. It is the fault that triggered the  6.7 1994 Northridge earthquake which caused $13–50 billion in property damage (equivalent to 24–93 billion today) and was one of the costliest natural disasters in U.S. history.
