British Columbia is widely known to be Canada's seismic danger zone, but every so often the shifting Earth reminds us that the rest of the country isn't immune to the sometimes fickle movements of tectonic plates. 

Early Sunday morning, residents of the small Nunavut communities of Resolute, Arctic Bay and Grise Fiord awoke to shaking caused by a magnitude 5.8 quake centred about 85 kilometres southeast of Resolute. No injuries and only light damage were reported, but the quake drew attention to the surprising seismicity of the Canadian High Arctic. 

As the map above, created for the June 2015 issue of Canadian Geographic, shows, Baffin Bay was actually the site of one of the strongest earthquakes in Canadian history, which occurred on Nov. 20, 1933. Measuring 7.3 on the Richter scale, it remains the largest known earthquake north of the Arctic Circle. 

Here are more of Canada's biggest quakes, in descending order of magnitude; their epicentres are also marked on the map.
