文摘

Tidally triggered earthquakes are observed on the San Andreas Fault. Stress shadows influence seismicity. Pore pressure is less than lithostatic in the upper crust of the San AndreasFault. Seismicity is correlated with tidal normal stress. Poroelastic conditions are different between the upper and lower crust.
