Book Description

The historical and geological record indicate that the earthquake hazard in south-western British Columbia is relatively high. This bulletin presents results of a major paleoseismological investigation consisting of several related interdisciplinary studies that extend the seismic record of the region into prehistory. Three introductory sections contain background material on the region's geologic and tectonic setting, earthquake sources, historical seismicity, and research methods used. This is followed by four sections summarizing paleoseismological research on the following indicators of possible past earthquakes: sea level changes, tsunamis and their deposits, liquefaction of ground, and landslides. The final sections are concerned with seismic hazards (ground motion, ground rupture, subsidence and flooding, tsunamis and seiches, liquefaction, landslides) and analysis of risk and recurrence of earthquakes.
