GREAT WATER PRESSURE AT SUBDUCTION ZONES MAKE GREAT EARTHQUAKES A HIGH RISK. This article explores the pressure between the PLATES off the coast of Chile. QUOTE--The stress build-up before an earthquake and the magnitude of subsequent seismic energy release are substantially controlled by the mechanical coupling between both plates. Studies of recent great earthquakes have revealed that the lateral extent of the rupture and magnitude of these events are fundamentally controlled by the stress build-up along the subduction plate interface. Stress build-up and its lateral distribution in turn are dependent on the distribution and pressure of fluids along the plate interface. THAT SOUNDS LOGICAL.... Its why SUBDUCTION of ocean plates underneath the continents produce such high magnitude earthquakes.
