AbstractThe sparsely populated region of Haida Gwaii, British Columbia, Canada (formerly known as the Queen Charlotte Islands) was struck on 27 October 2012 by a magnitude (Mw) 7.8 earthquake -- the second largest earthquake in Canada's written history. It was felt throughout British Columbia and into neighboring provinces, territories, and states, as far as 1600 km from the event’s rupture zone. Throughout Haida Gwaii, the shaking reportedly lasted 1.5 - 2 min, with about 30 s of especially strong shaking. Despite there being only light building damage and few, minor injuries, many of the inhabitants of Haida Gwaii found the earthquake and its numerous aftershocks to be a truly upsetting experience. Through public meetings and face-to-face interviews, the first author and other scientific presenters endeavored to mitigate the earthquakes' psychosocial impacts. Myths and misconceptions regarding earthquakes and tsunamis had to be addressed diligently. Lessons learned might be applied to future significant geohazard events, and we provide a summary of those lessons here.
Summary(Plain Language Summary, not published)
The magnitude 7.8 earthquake of October 2012 occurred in the sparsely populated region of Haida Gwaii, British Columbia (formerly the Queen Charlotte Islands). This was the second largest recorded earthquake in Canadian history and was felt throughout British Columbia and as far away as the Yukon, Alberta and Montana. The perceivable shaking lasted roughly 1.5 minutes, with very strong shaking for about 30 seconds. Although building damage was light and there were few, minor injuries, many of the Haida Gwaii inhabitants found the earthquake and its aftershocks a traumatic experience. Through public meetings and face-to-face interviews, we endeavoured to mitigate the earthquakes' emotional impact. Myths and misconceptions on earthquakes and tsunami were addressed immediately
