The March 11, magnitude 9. But don't worry—you won't notice the difference. His calculations indicate that by changing the distribution of Earth's mass, the Japanese earthquake should have caused Earth to rotate a bit faster, shortening the length of the day by about 1. This quake is commonly called the Assam-Tibet earthquake or the Assam earthquake, even though the epicenter was in Tibet.

The quake struck at the intersection of the most vigorous collision of continental plates on the planet, where the Indian continental plate smashes into the Eurasian plate and dives beneath it.

The slow-motion crash helped create the massive Himalayas. More than 1, people were killed, with hundreds more injured, mostly in Nias, in northern Sumatra, Indonesia. The quake hit just months after an even bigger earthquake destroyed the region see entry 3.

The quake ruptured below the surface of the Indian Ocean, where the Indo-Australian Plate is pushing under the Eurasian plate at the Sunda trench, similar to the quake. Alaska had been a state for only 7 years when this huge earthquake triggered a tsunami of over 30 feet 10 meters. Despite its size, the quake caused little damage due to its remote location at the tip of the Aleutian Islands. The temblor was the result of the Pacific Plate diving beneath the North American Plate at the Alaska-Aleutian megathrust, which has been the location of many megathrust earthquakes.

The quake cracked wood buildings and split an asphalt runway. Hairline cracks also formed in the runways at the U. Coast Guard Loran Station. A catastrophic magnitude 8. The tsunami spread along the coast of Central America, and even stretched to San Francisco and Japan.
