Quakes 'could rupture glacial lakes'

Glacial lakes in the Himalayas could pose a major hazard to population centres if they are ruptured by earthquakes, scientists say.



The true risk to settlements and infrastructure downstream in the Hindu-Kush-Himalayas region is difficult to assess.

But the Himalayan region is dotted with glacial lakes and is in a seismically active zone.

Experts say that, on the basis of past records, a large quake in the region is overdue.

Many glacial lakes are said to be growing - some of them alarmingly - because of melting glaciers.

Some are at risk of rupturing, which would flood areas downstream.

There have been at least 35 glacial lake outburst events in Nepal, Pakistan, Bhutan and China during the last century, according to the United Nations Environment Programme (Unep). More >>>
