— A magnitude 9 quake struck deep beneath the Indian Ocean off the coast of Indonesia Sunday.
— It was the most powerful earthquake in the world in four decades.
— The quake occurred more than 6 miles deep and was followed by a half-dozen powerful aftershocks.
— A 620-mile section of a geological plate shifted, triggering tsunamis.
— Walls of water sped away from the quake's epicenter at more than 500 mph before crashing into shorelines.
— Tsunamis as large as Sunday's happen only a few times a century.
— A tsunami is a series of traveling ocean waves generated by geological disturbances near the ocean floor.
— With nothing to stop them, the waves can race across the ocean like the crack of a bullwhip.
— They gain momentum over thousands of miles.
INTERNATIONAL TSUNAMI WARNING SYSTEM
— Started in 1965, one year after tsunamis associated with a 9.2 magnitude quake struck Alaska.
— Member states include the major Pacific rim nations in North America, Asia and South America.
— Administered by the U.S.-based National Oceanic and Atmospheric Administration.
— No such warning system exists in the Indian Ocean.
— Scientists said deaths would have been reduced if one had.
— Thai officials issued the only warnings of the impending disaster, but broadcasts underestimated it.
— A Web site caution was not posted until three hours after the first waves hit in Thailand.
— The World Conference on Disaster Reduction next month in Japan will discuss an Indian Ocean warning system.
