WorldScientists piece together deadly Nepal-Tibet flash floods
The US Geological Survey says the disaster was caused by a glacier collapse and debris flow that produced catastrophic downstream effects. At least 350 people have died and 900 are missing, including about 500 foreign tourists. Experts are still examining how the flood developed, while warning that climate change, monsoon conditions and inadequate cross-border information-sharing may heighten the risk.
