SANTIAGO, Chile (AP) -- Melting ice in southern Chile caused a glacial lake to swell and then empty suddenly, sending a "tsunami" rolling through a river, a scientist said Thursday. No one was injured in the remote region.

Cachet Lake is shown partially dried in early April, next to the Colonia glacier.
Glacier scientist Gino Casassa said the melting of the Colonia glacier, which he blamed on rising world temperatures, filled the Cachet Lake and increased pressure on the ice sheet.
The water bored a 5-mile (an 8-kilometer) tunnel through the glacier and finally emptied into the Baker River on April 6.
