There are about 4,000 earthquakes in and near Canada that are recorded annually by Natural Resources Canada (NRCan). While this works out to about 11 earthquakes per day, only about one quake per week is felt, according to the federal department.
Ahead of a feature story about earthquake preparation in Canadian Geographic's June issue, we mapped one year of earthquakes, ending April 21.
During that year, NRCan recorded 4,120 quakes. Notice most earthquakes occur along the active plate boundaries off the British Columbia coast and along the northern Cordillera and arctic margins. Other areas that frequently see earthquakes are the Ottawa and St. Lawrence Valleys, New Brunswick and the offshore region south of Newfoundland, according to NRCan.
Use the map above to find out the magnitude and location of each earthquake, as well as whether it was felt.
