Earthquake (PGV 125mm/s) - Hazard Extent - DCRRA

This earthquake hazard layer represents regions with a seismic peak ground velocity hazard of 125mm/sec, and is threat indicator for brittle pipe (typically segmented) such as water pipelines.

This is one of four earthquake ground motion layers created by BGC as an input for this study. Ground motion is the transient shaking felt at earth’s surface as seismic waves pass by. This shaking can threaten assets depending on the shaking intensity and asset type. Ground motions generally increase with earthquake magnitude, decrease with distance to the source, and depend on the style of faulting, the position of the site with respect to the relative motion between blocks, the stiffness of rock between the source and site, and site soil and topographic conditions. Although there are many metrics to quantify shaking intensity, BGC has selected peak ground acceleration and peak ground velocity for the provincial-scale hazard threat analysis. This layer represents regions with a seismic peak ground velocity hazard of 125mm/sec, and is threat indicator for brittle pipe (typically segmented) such as water pipelines.
