Changes in static stress on southern California faults after the 1992 Landers earthquake
Abstract
An elastic half-space model is used here to estimate the stress changes produced by the Landers earthquake on selected southern California faults, including the San Andreas. It is found that the estimated stress changes are consistent with the triggering of four out of the five aftershocks with magnitude greater than 4.5, and that the largest changes, occurring on part of the San Bernardino segment of the San Andreas fault, may have decreased the time to the next magnitude 8 earthquake by about 14 yrs.
