Earthquakes, Even Small Ones, Unusual in the Kootenays - The Northern View
Earthquakes Canada said the shallow quake was felt in Nelson, Cranbrook and Trail, and officials reported no damage or injuries.
At 5:30 a.m. PT on the east shore of Kootenay Lake near Grey Creek, a 3.7-magnitude earthquake struck, as reported by Earthquakes Canada. Residents throughout the Kootenays, including Nelson, Trail, and Cranbrook, reported feeling the tremor.
Although earthquakes occur in the Kootenays, they are usually very small, according to seismologist Camille Brillon of Natural Resources Canada. The tremor was perceived as alarming for an area with low seismicity.
No damages or injuries were reported. Historical quakes in the region include a 6.0-magnitude event 118 years ago near Valemount in the Rocky Mountains and a 5.5-magnitude quake near Prince George in 1986.
Brillon recommends residents prepare for emergencies by assembling "an emergency kit that can last you at least 72 hours" for family and pets, ideally lasting two weeks.
Because the Kootenays lack plate boundaries, there is no evidence suggesting a larger earthquake will occur soon. Offshore Vancouver Island, however, features a stuck plate boundary that will eventually produce a magnitude 9 earthquake.
