Richmond’s Buildings are Expected to Perform Well
Much of Richmond is newer construction, built to meet then requirements of the National Building Code of Canada. This code has, since 1953, included earthquake-resistant standards, including provisions for construction on softer soils.
Commercial buildings designed in accordance with the earthquake-resistant provisions of the National Building Code of Canada are anticipated to perform well in a large earthquake. Research into the seismic design and construction of residential wood frame buildings has helped to highlight ways to improve earthquake performance. This has led the City to require that builders and developers of residential wood frame buildings review and consider the seismic and design aspects of the Canadian Wood Council's "Engineering Guide for Wood Frame Construction" for all new buildings. The City of Richmond is committed to continued enhancement of seismic design standards for earthquake preparedness, and will modify standards as required in light of relevant research。

Liquefaction May Occur, but Richmond Won't Melt into the Ocean
During an earthquake, shaking can
cause loosely packed, water-saturated sediments such as sand or mud to turn into a fluid mass. This is known as liquefaction. When this happens the sediments lose their strength and can no longer fully support structures, which may lean or settle.
Some degree of liquefaction can occur during an earthquake depending on the location, size and duration of an earthquake. Some homes and buildings could settle and crack and roads and other surfaces could become uneven due to soil failure. Take comfort in the fact that the area known as Richmond has been around for over 5000 years and has successfully weathered countless earthquakes
