Mechanics of nonplanar faults at extensional steps with application to the 1992 M 7.3 Landers, California, earthquake

Earthquakes that rupture across steps between faults can be larger than those predicted from individual fault lengths, making understanding multifault events critical to assessing earthquake hazard. Empirical data from earthquake surface ruptures suggest that the distances between faults that ruptur...
