Question
: Is it possible that the malleability of the Brawley Spreading Zone hides the continuation of the San Andreas to the Imperial Fault? Glenn
Answer
Hi Glenn,
The San Andreas fault system includes the Imperial Fault, south of the Salton Sea. The fault system bends near the Salton Sea resulting in extensional stresses (pull-apart) in the southern end of the Salton Trough (Sea). Further south in the Gulf of California, the San Andreas system transforms into a spreading center. (That is not shown on this illustration.)
