Summary(Plain Language Summary, not published)
This presentation discusses seismic risk in the Ontario Region, including a description of why earthquakes occur in Ontario and the results of a scenario model for the Ottawa region. This scenario is not a real event, but is meant to illustrate some of the worst-case elements of a future large earthquake in this area. Although large earthquakes in Ontario are more rare than in other areas, these events have occurred and will happen again in the future. This presentation is meant to aid practitioners in understanding the risk and potential impacts.
