namcoFor nearly a decade, geologist Dallas Abbott and her colleagues have been trying to prove that an enormous space rock, possibly an asteroid, smashed into the Indian Ocean about 10,000 years ago and created a megatsunami, a t of giant waves that washed over the east coast of Africa. Such a tsunami could have created waves as high as 300 feet (91 meters)—three times larger than the Indian Ocean tsunami in 2004 that left 230,000 dead.

这样的海啸能够制造300英尺的波浪(91米)，是2004年造成230,000人死亡的印度洋海啸的三倍之多。

The proof, Abbott contends, lies in sandy wedge-shaped features called chevrons in Madagascar, as well as what might be a deep ocean crater between Madagascar and Australia. The idea is that either a huge impact, or a large landslide from a volcano on the island Réunion, sparked the tsunami that created the chevrons.

这个观点是巨大的撞击或是R岛上火山山崩引起了产生山形袖章的海啸。
Now, Abbott and an international team of rearchers have prented further evidence to back up their theory: a geo-chemical fingerprint from Madagascar that firms up the date for the massive tsunami. The study of ancient megatsunamis has been controversial, though; not only is it hard to detect evidence that literally washes away, but also to establish proof of a tsunami”s cau—such as an impact or earthquake—occurring at the same time.

可是古代大海啸的讨论是有争议性的，不仅仅是由于很难去探测那些实在地被冲走的证据，还由于确定海啸的缘由-比方说是撞击或是地震-是发生在同一时间的。
