The Great Alaska Earthquake lasted for nearly five minutes and registered a magnitude of 9.2, still the largest ever recorded in North America and second only to the 9.5-magnitude quake that struck Chile in 1960.
This magnitude 7.9 shock was felt by residents over 400,000 square miles of Alaska, as far south as Seattle, Washington, and east to Whitehorse, Yukon Territory, Canada. The largest magnitude earthquake in the central interior of Alaska since October 1947 occurred on October 29, 1968.Rated magnitude 6.5, the shock centered southeast of the village of Rampart, on the Yukon River.ore than 80 percent of the planet's tremors occur in the circum-Pacific belt, and about six percent of the large, shallow earthquakes are in the Alaska area, where as many as 4,000 earthquake at various depths are detected in a year. Early reports of earthquakes in Alaska are fragmentary.
