Mapping a year of Canadian earthquakes


Posted by in Mapping on Monday, May 4, 2015



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.

I felt a couple very slight ones in Nelson, BC during the summer/fall of 2014 but wasn't sure how to report them. They were similar to the ones we would get in Salt Lake City, Utah when I lived there.

In January, 1982, we were staying overnight with friends in Blackville, New Brunswick. The next morning at breakfast time, the house began to shake and things started rattling and bouncing. We rushed outside, not sure what was happening. We found out later in the day that there was an earthquake magnitude 5.9 in an isolated area of northern New Brunswick. No injuries, only minor damage. Since we moved to Quebec, we have experienced several minor earthquakes.

Earthquake is a natural disaster that can occur everywhere. The nations and people just have not been prepared for such natural disaster. Even with minimum of resources regarding their houses, the government can in another way tell the community to flee or evacuate during the disaster. However, the community was not prepared for disaster preparedness. The nations should be aware of their location in seismic risk.
