Geoscience Map 2010-3: Liquefaction Hazard Map of Richmond, British Columbia
View Map (PDF 4.1 MB)
The City of Richmond, British Columbia, is located in one of the most seismically active regions in Canada (Rogers, 1998). The effects of earthquakes are not only dependent upon the magnitude of the earthquake and the distance from the source, but can vary considerably due to local geological conditions. These conditions can be mapped using existing geological and geotechnical data. This map shows the variation in the earthquake-induced liquefaction hazard in the City of Richmond, BC. The city is located entirely within the modern Fraser River delta, and the deltaic sediments on which the city is built are particularly susceptible to earthquake induced liquefaction (e.g. Byrne, 1978; Finn et al., 1989; Byrne and Anderson, 1991; Clague et al., 1992, 1997, 1998b; Watts et al., 1992). This map has been prepared as part of an earthquake hazard mapping project in the city. An accompanying map shows the Quaternary geology of the Richmond area (Geoscience Map 2010-2).
