NEW YORK (AP) _ The magnitude-8.9 earthquake that struck Indonesia Sunday was the world's fifth most powerful since 1900 and the strongest since a 9.2 temblor slammed Alaska 40 years ago, U.S. earthquake experts said.

The globe's most potent quake since 1900 struck with a 9.5 magnitude in Chile in 1960. The quake in Prince William Sound Alaska occurred in 1964, the U.S. Geological Survey's Web site said.

A magnitude 9.1 quake hit Alaska's Andreanof Islands in 1957, and a 9.0 temblor rumbled on Russia's far eastern Kamchatka peninsula 1952.

Other major quakes and their magnitudes were: Ecuador, 8.8 in 1906; Alaska, 8.7 1965; Tibet, 8.6 1950; Kamchatka, 8.5 1923; Indonesia, 8.5 1938; and the Kuril Islands, 8.5 1963.
