The 1929 Grand Banks earthquake occurred on November 18 of that year.

In the Atlantic Ocean, off the south coast of Newfoundland, a seaquake of Richter 7.2 occurred. The quake was centered on the edge of the Grand Banks, about 250 km south of the island..

The quake was felt as far away as New York.

The quake also snapped 12 submarine transatlantic telegraph cables.

It triggers a tsunami that destroys many south coast communities in the Burin Peninsula area, killing 28. 10,000 were left homeless.

The tsunami arrived in three waves, up to seven metres high, about three hours after the quake.

Relief was prevented from reaching the affected areas by a blizzard that struck the day after.

As of 2004, it is the only tsunami to strike Canada's east coast.
