November 1929 Grand Banks, Canada Images
On November 18, 1929, at 5:30 pm local time, an earthquake occurred approximately 250 km south of Newfoundland along the southern edge of the Grand Banks. The earthquake triggered a large submarine slump which ruptured 12 transatlantic cables in multiple places, and generated a tsunami. More than 40 local villages in southern Newfoundland were affected, where numerous homes, ships, businesses, livestock and fishing gear were destroyed.
