Abstract: The California Department of Transportation (CALTRANS) considers earthquake effects in planning, design, and construction of their structures. Obviously, CALTRANS has to respond to damaging earthquakes. The earthquake effects are primarily caused by strong ground motions and surface fault rupture displacements with possible liquefaction of soils and slope instabilities. CALTRANS estimates expected earthquake effects from the potential of Maximum Credible Earthquakes (MCE’s) caused by younger (late Quaternary and younger) earthquake sources or faults in and adjacent to California.
