A massive tsunami in northwestern Sumatra wiped out coastal villages for miles. Only one survived. But by a century later, its influence began to wane -- the result of a new power settling on the sites of the destroyed villages.
Archaeologists began studying the area in detail after another tsunami, in 2004, killed more than 150,000 in Sumatra alone. And in 2006, one researcher discovered bits of pottery and Muslim gravestones that were uncovered by the 2004 tsunami. He recruited a large team to study a 25-mile stretch of coastline in a region known as Aceh.
