The largest earthquake recorded on the North American continent occurred in Anchorage, Alaska March 27, 1964

This 9.2 earthquake devastated the oil industry city of Anchorage in four minutes. Landslides were set off and the clay under the city slid towards the sea causing 50,000 square miles. The epicenter was out in the Pacific Ocean in Prince William Sound. The sea floor rose as much as 30 feet generating large undersea waves. A 30 foot high tsunami (wave) rolled into the port of Seaward carrying burning oil. Two more waves hit and washed the port into the ocean. In all 131 people lost their lives.
