A selection of earthquake scenarios for government planning purposes in 2021 / T.E. Hobbs. : M183-2/8853E-PDF

"This document describes three earthquake scenarios developed for government planning purposes in 2021. They were requested from Natural Resources Canada, which holds federal subject matter expertise on seismic hazard and risk, by Emergency Management British Columbia and the Government Operations Centre in Ottawa, and are presented in an Open File report to allow for appropriate review and documentation. While the events were developed for particular government agencies, the scenarios are relevant for other applications and hence their documentation may be useful to other emergency management, planning, and preparedness organizations, and to the broader public. This file presents a description of the impacts due to the following scenario earthquakes: a moment magnitude (Mw) 7.0 event in the Strait of Georgia near Vancouver, BC; a Mw 7.3 event on the Leech River Fault near Victoria, BC; and a Mw 7.5 event in Gatineau, QC, near the nation's capital. The seismic hazard and risk assessment is performed in the same manner as the National Seismic Risk Assessment, which leverages the current best understanding of: seismic sources and ground motions, site conditions, exposed assets, and fragility curves. In this document, sources will be cited as appropriate to support the scientific description of the events, but the text will generally be aimed at a non-technical audience"--Introduction, page 1.
