We started at the lighthouse, standing on the Westcliff marine terrace. Here we discussed the Loma Prieta earthquake (1989) and if it is a "representative #earthquake" that explains the uplift of the Santa Cruz Mountains.

Loma Prieta took place on a left-step in the San Andreas #Fault. Left-steps in Right Lateral Faults lead to compression and a thrust component. It is one way to build mountains. #LomaPrieta #SanAndresFault #SAF
