Listening for avalanches

The 2013-2014 season has been particularly deadly in the Alps in terms of avalanches, with 13 fatalities in Switzerland alone so far.

Researchers from Europe's centre for avalanche forecasting - the WSL Institute for Snow and Avalanche Research - are employing new technology to improve their chances of predicting and preventing these disasters.

Here, Dr Alec Van Herwijnen from the WSL Institute for Snow and Avalanche Research explains why burying microphones under the snow could improve avalanche forecasts.
