Abstract
This paper presents observations from field studies and physical model tests to investigate the response of soil deposits to strike-slip bedrock faulting. The study is relevant to developing mitigation technique against fault-induced damage in structures located near potentially active faults. Observations of ground rupture patterns in alluvial materials following the 1992 Landers earthquake are presented. Particularly important are the observations of significant deformation away from the main trace, the width of the shear zone, and the effects of the surficial geology on the fault expression. Preliminary results from small-scale model tests simulating strike-slip rupture are also presented. The tests results confirm that the width of the shear zone depends primarily on the ductility and height of the soil deposit. These studies provide insight regarding ground deformation patterns in the soil overlying strike-slip faulting.
