Thrust faults: these are similar to reverse faults except the angle is 45 degrees or less. Normal fault: the hanging-wall has moved down relative to the footwall. Active: movement during the past 11,600 years. Potentially active: movement during the past 2. 6 million years. Inactive: no movement during the past 2. 6 million years.
