Wednesday, November 18th 2020, 5:30 am - It's been 91 years since a magnitude 7.2 earthquake shook Newfoundland and caused a deadly subsequent tsunami.
On November 18th, 1929, a 7.2 earthquake shook Newfoundland, but the story starts between 201 million to 174 million years ago when Pangea, the supercontinent, started to break apart.
Fast-forwarding a few hundred million years later, but not quite to the point where Newfoundland joined Canada in 1949, the country of Newfoundland experienced a major earthquake and a deathly tsunami.
The earthquake was felt on November 18th at 5:02 pm. The quake’s epicentre was located about 400 kilometres south of the Grand Banks of Newfoundland.
The earthquake was sizable, but it's the subsequent tsunami that makes this day notable in Newfoundland's history.
The tsunami waves reached 3 - 8 metres high as they crashed ashore on the Burin Peninsula.

It crashed the communities of the Peninsula causing 27 deaths and leaving more than 1,000 people homeless.
These tsunami waves were travelling at 700km/h. Because tsunami waves travel so quickly, it's difficult to see them coming and prepare accordingly.
