图片新闻【490】南亚东南亚多国地震海啸造成1万2千人死亡

More than 12,300 people were killed and tens of thousands left homeless after a powerful undersea earthquake unleashed giant tsunami waves that crashed into the coasts of south and southeast Asia.

The 8.9 magnitude earthquake that struck off the Indonesian island of Sumatra early on Sunday was the biggest in 40 years.

It triggered waves that reared up into walls of water as high as 10 meters (30 feet) as they hit coastlines in Indonesia, Sri Lanka, India and Thailand.
