Abstract(unpublished)
This is an overview article for a special issue on the 2012 Haida Gwaii and 2013 Craig earthquakes containing 19 original research papers.
Summary(Plain Language Summary, not published)
The magnitude 7.8 earthquake of October 27, 2012 was the largest thrust earthquake ever recorded along the mainly strike slip margin to the west of Haida Gwaii on the coast of British Columbia. It was followed by a magnitude 7.5 earthquake on the same plate boundary slightly more than 2 months later farther north in southeastern Alaska. This article summarizes 19 original research papers appearing in a special issue focussing on these two earthquakes. It includes papers describing the geological setting, the characteristics of the earthquakes and their aftershocks, and other consequences of the earthquakes, such as intensity of ground shaking. The research improves understanding of large thrust and strike-slip earthquakes and has applicability in other seismically-active regions of Canada.
