Abstract: We document a case history of Northridge earthquake induced movement of a coherent landslide mass comprised principally of weathered, previously sheared siltstone. Information on the residual shear strength of the material ...

Abstract: Permanent ground deformations in unsaturated, compacted hillside fills under seismic loading conditions are discussed, with emphasis given to fill performance during the 1994 Northridge earthquake. These movements represent ...

Abstract: Seismic compression is defined as the accrual of contractive volumetric strain in unsaturated soil during strong shaking by earthquakes. We document and analyze two case histories (denoted school site and site A) of ground ...
