AbstractOctober's magnitude 7.7 earthquake is the second largest recorded in Canadian history. It was felt throughout British Columbia and as far away as the Yukon, Alberta and Montana, roughly 1500 km away (Figure 1). Nevertheless, this earthquake resulted in limited damage partly due to the population centres being located at least 80 km from the epicentre and at least 60 km from the fault rupture. While little visible impact and few, minor injuries resulted, many people were significantly traumatized by the experience, and the numerous felt aftershocks.
