Experts redirect water to curb post-quake tragedies

The 2008 Wenchuan earthquake rattled and crumbled the peaks that smatter Sichuan province's Longmen fault line, creating a recipe for later disasters. Just add water, and you get landslides.

So, the Wenjia Valley's landslip-prevention formula is to subtract the water from the loose soil and stones.

Experts constructed two dams and one diversion channel past the water source that fed six avalanches from the 2008 tremor until 2011. No landslides were recorded there before the quake.
