@braintenacity: What Actually Caused The Nepal Flood? A wall of water came down the valley at Rasuwagadhi on the Nepal-China border - and it had not been raining there. The first thing anyone detected wasn’t rain or a rising river. It was a seismic signal, which is why the earliest reports said earthquake. The US Geological Survey re-analysed the waves and concluded the energy came from a landslide, not a quake. The leading explanation: a mass of glacier ice and rock sheared off a mountainside and fell into a tributary of the Bhote Koshi, turning to water on impact. Thirteen months earlier, a glacial lake on the Tibetan side burst and destroyed the bridge at that same crossing. Same border. Same river. Still no shared warning system.
