Large earthquakes in #Canada ?

On this day in 1949, a damaging M8.1 #earthquake (one of the largest ever recorded in #NorthAmerica) struck off #HaidaGwaii. Shaking was so strong that cows were knocked off their feet and a geologist working close to the epicentre could not stand up.
Shaking was felt across most of #BritishColumbia, parts of Alberta, #washington Yukon and Alaska: https://earthquakescanada.nrcan.gc.ca/historic-historique/events/19490822-en.php
