Why Winnipeg has more earthquake than Ottawa?

Winnipeg experiences more earthquakes than Ottawa primarily due to its geological setting. Winnipeg is located near the boundary of the North American Craton, where ancient tectonic features can still cause seismic activity, while Ottawa is situated on more stable geological formations. Additionally, the types of stress and strain in the crust around Winnipeg can lead to more frequent minor earthquakes. Overall, the geological history and structural dynamics of the region contribute to the difference in seismic activity between the two cities.
