(Newser) – Melting ice in a remote Chilean lake caused it to swell and suddenly empty, creating a “river tsunami,” the AP reports. Water from a melting glacier filled the lake and tunneled through the ice, emptying into a nearby river.

“The mass of water moved against the current of the river,” said an expert. “It was a real river tsunami.” He said the “basic cause” was global warming. “This is a phenomenon that occurs periodically during the summer,” he added.
