More than a week after Nepal’s catastrophic floods, the scale of destruction is becoming clearer. An enormous glacial avalanche near Langtang Lirung sent millions of tonnes of ice, rock and debris cascading into the valleys, devastating the Nepal-China border and transforming the Trishuli-Bhotekoshi river system more than 100 kilometres downstream. From the obliterated Friendship Bridge and Trishuli Bazaar to shattered roads and bridges-and the remarkable survival of a family inside a lone green house-NDTV traces the path of the disaster and examines the enormous challenge Nepal now faces.
