World - AP Asia Big Earthquake Hits Off Indonesia Island
BANGKOK, Thailand - A large earthquake struck off Indonesia's Sumatra Island in the Andaman Sea late Monday, and the U.S. Geological Survey said it was a major quake measuring a magnitude of 8.2.
Thai officials issued a warning of a possible tsunami, three months after a tsunami devastated parts of Indonesia and other countries in the region. The quake occurred at 11:09 p.m. local at a depth of nearly 19 miles, the USGS in Golden, Colo., said.
Japan's Meteorological Agency measured the quake at magnitude 8.5.
The magnitude-9 undersea earthquake, the world's biggest in 40 years, and the huge tsunami it sent charging across the Indian Ocean at the speed of a passenger jet killed more than 174,000 people and left another 106,000 missing.
More than 1.5 million people were left homeless in 11 countries.
