The (M w 6.2, 7.4, 6.3) 1992 Landers sequence that began on 23 April with the M w 6.2 1992 Joshua Tree preshock is the most substantial earthquake sequence to occur in the last 40 years in California. These earthquakes ruptured almost 100 km of both surficial and concealed faults and caused aftershocks over a 100 km wide and 180 km long area. The faulting was predominantlv strike-slip and all three events had unilateral rupture to the north away from the San Andreas fault.
