A massive landslide equivalent to the force of a 5.2-magnitude earthquake struck near the Nepal-China border on Wednesday morning, triggering catastrophic flash flooding that killed more than 150 people and left hundreds missing, according to officials and reports.
This is seriously scary. CCTV footage from Gyirong Port in Tibet, China, directly opposite Nepal's Rasuwa district. This flash flood hit here first and later caused massive havoc in Nepal.

The flooding was reportedly triggered after a powerful landslide blocked the Bhote Koshi River, sending a huge volume of water downstream from China into Nepal. Scientists believe a glacier may have broken off and fallen into the valley, potentially triggering or worsening the landslide and subsequent flooding.
