  • Long-term measurements of earthquake ground motions offshore, using the Sandia National Laboratories' SEMS device which records only the strongest motions and transmits them upon command to a boat at the surface, have shown that offshore ground motions may in certain cases be substantially different from empirically predicted ground motions based on onshore data. In particular, the attenuation effects of soft and/or gassy soils, the wedging of offshore deposits as a function of direction to and… CONTINUE READING
