AB: Evaluations of seismic risk on national and regional scales are an important factor in preventing and mitigating natural disasters caused by earthquakes. We review the history of earthquakes and tsunamis in Canada and summarize the current knowledge of seismogenic zones, the frequency of large events and the risk of tsunamis. We also describe the response of the Canadian government, universities and industry to better understand the seismic risk in the country. This includes the current Canadian monitoring and research activities using the National Canadian Seismograph Networks as well as the more specialized Southern Ontario Seismic and POLARIS (portable) networks. In addition to the research carried out to improve our understanding of seismicity, we discuss briefly the work done in the past twenty years by the LITHOPROBE (deep crustal exploration) project which was designed to help clarify the tectonic history of the country. The paper concludes with a description of the current and planned applications of advanced technology to mitigate earthquake and tsunami hazards in Canada.
