It happened five kilometres north of Banff at 17.3 kilometres under Cascade Mountain. A Canadian seismologist said the 3.9 magnitude earthquake was not unusual. The earthquake, which occurred at 6:33 p.m. was also reported as 4.4 magnitude by the United States Geological Survey. The reason for the two measurements is because Canada uses a different set of seismic stations that are closer to the town, which gives a more accurate number. It was classified as a light earthquake and a magnitude four has 10 times more shaking and ground displacement than a magnitude three. Alberta experienced 605 earthquakes between 1985 and 2011.
