Scientists Link Nepal Floods to Possible Ice-Rock Avalanche

Scientists are trying to understand what caused the sudden floods in Nepal.

They think a large mass of ice and rocks may have fallen into the Lhende River.

The debris may have blocked the river and created a temporary lake.

When the blockage broke, mud, rocks and water rushed into the Bhote Koshi River.

The flood destroyed bridges and other infrastructure and killed hundreds of people, according to the report.

An earthquake was first suspected, but scientists later said the seismic signal was probably caused by the collapse and debris flow.

Another possible lake has formed downstream, which could create more flooding if its natural dam breaks.

Experts are still studying satellite images and monitoring the area.
