Abstract
This study explains the origin of the deforming structures between the San Andreas fault and the Salton Sea within the Salton Trough in Southern California. ShakeOut simulations and other studies model shaking resulting from a large rupture on the San Andreas fault. These models simulate a start at the southern fault tip of the San Andreas fault that propagates to the northwest. A secondary strand of the San Andreas fault called the East Shoreline fault is located at the southern tip of the San Andreas fault near the shoreline of the Salton Sea. Between the East Shoreline fault zone and San Andreas fault is dominantly contractional and strike-slip faults leading to the uplift of Durmid Hill.
The main purpose of this study is to map and analyze the San Andreas fault zone, East Shoreline fault zone, and the structural geology between these two faults. The San Andreas fault zone is characterized by a wide strongly developed damage zone that is up to about 0.5 km wide. The discovery and characterization of the East Shoreline fault is especially important because this strand of the San Andreas fault system could buffer the main strand from large triggered slip events.
