The Nepal floods question: When the Himalayas collapse, who gets warned?
The floods raised concerns about cross-border warnings that experts say can no longer be ignored.
New Delhi, India – On the morning of August 26, the Himalayan landscape above Nepal’s Rasuwa district changed in minutes.
A mass of ice and rock broke loose high in the mountains and sent a violent surge of water, mud and debris down the Lhende Khola River. The torrent travelled through valleys, swept away settlements and infrastructure and eventually reached the Nepal-China border.
By mid-September, more than 1,400 people had been reported dead and at least 6,000 remained missing in Nepal and across the border in Tibet. Twelve hydropower plants were destroyed, while roads, bridges and homes were buried or washed away.
But technology alone cannot solve the problem. A sensor can detect a change. Someone still has to receive the message. Someone has to understand what it means. And people downstream have to have a route to safety.
