How avalanches are triggered in Himalayas revealed
Washington: Researchers have said that the amount of snow needed to trigger an avalanche in the Himalayans can be up to four times smaller than in the Alps.
The proposed universal model from a materials scientist at Queen Mary University of London could have implications in better understanding strategies for mitigating natural hazards related to snow and rock avalanches and safeguarding people on mountain villages, roads and ski resorts.
By using a branch of mechanics that aims to understand how cracks spread in solid structures, Professor Nicola Pugno from Queen Mary`s School of Engineering and Materials Science demonstrated that the snow needed to trigger an avalanche at 8,000m can be up to four times smaller than at half the height of 4,000m.
The Himalayans mountain range in Asia is home to some of the highest peaks in the world.
Professor Pugno said that the research demonstrates that an avalanche on the Himalayas could be more dangerous than on the Alps, for instance, due to the larger size scales of the first mountains.
