The massive lake caused by the Chinese earthquake was still rising today despite military efforts to blast away the wall of debris that created it.

A Chinese state news agency reported a “relatively strong” aftershock has rocked a quake-formed lake that has been threatening to burst.

Soldiers blew up wooden houses and other debris today in a lake formed by China’s deadly earthquake to speed the flow of water into a diversion channel and ease the threat of flooding for more than 1 million people in the sprawling disaster zone.
