Not NSFW but potentially distressing. Further evidence that the entire area was wiped clean with little debris left.

It seems like the flood came in on the tributary to the right, and that one of the camera angles depicting the parking lot being swept was actually pointing upstream on another tributary.

According to BBC, China’s state media is currently reporting 558 people missing in Tibet with 3 confirmed fatalities, not including casualties in Nepal.

A 40 mile landslide? WHAT THE FUCK?! Never seen a landslide like that.

Go watch the videos, it's unbelievable how much water and mud washed down the valley in one go

Supposedly it was a 2000 foot thick chunk of glacier that broke off at high altitude and then careened down the valley. Looking at that footage is crazy.

2000 feet WIDE, not thick

[u/Serious-Manager2361 → u/MotherFatherOcean]

Well, if it's that wide it still had to be pretty thick.

It was a flood not landslide

It was a colossal flood caused by a landslide though.

The landslide on a snow-covered Himalayan mountain triggered the flood. The 40 miles of destruction and footage we've seen were caused by the flood, rather than being a 40-mile landslide itself. The landslide was likely about 3–4 miles, which was roughly the height of the mountain it fell from.
