+ Initiation of major plate boundary strain in the Salton Trough region at ca. 8 Ma
+ Latest Miocene to Pleistocene West Salton detachment fault and supradetachment basin
+ Initiation of the San Jacinto and Elsinore faults at ca. 1.2 Ma
+ Rapid vertical crustal motions involved in strike-slip deformation (e.g. exhumation of Fish Creek Mts crystalline rocks from 5.5 km depth to the surface in the past 1.2 Ma)"
