Why is that relevant? Because they chose to live in a super steep valleys of the Himalayas? I'm grasping to understand what your rating of a country has to do with geology and physics.

Folks look so small against the landscape, it's hard to comprehend water and boulders moving that fast. I didn't catch the guy trying to climb the first time, I was looking for the red truck. Seems he bailed and started going up the slope instead of trying to outrun it in that 4 banger POS. Smart move.

At the root of it all, when mother nature decides to do what she wants to do nothing man made is gonna stop it never has never will ...

100 percent nightmare fuel. They has no chance. As someone else posted, we are like fleas on a dog to the Earth. We are incapable of matching the sheer power and force of Mother Nature once she gets pissed off.

Death toll now up to 547.
Apparently, a new alert was issued a few hours ago for another breach of an associated river blockage/dam on the Tibetan side. Water on the backside of the blockage/dam began to rise and formed a new lake. The "dam" started to give and send water and debris downstream. Communication has been hard due to phone lines being down and all the other damage. Getting the alert out was a problem, I'm sure.
I haven't seen much about impacts of this yet, so hopefully it isn't much.

A new lake formed above the disaster zone on the Nepal and China border. This morning it started overflowing.
That sounds like relief. It is the opposite. Overflowing is how these things fail.
Here is why.
On Wednesday the flood and landslide left behind a huge pile of rock, mud and ice sitting across a river valley near Gyirong, on the Tibet side of the border. The river kept flowing and could not get past it.
So a lake formed behind it. This is called a barrier lake. The wall holding it is not a dam. Nobody designed it. It is loose debris that happened to land there.
Chinese authorities say the water in it is around 2 million cubic metres.
For 48 hours that lake rose. Late this morning, Chinese state television reported the water has started running over the top of the barrier, and has not stopped.
Now the mechanism, and it is the whole point of this post.
A proper dam has a spillway. It is built to let water pass over the top safely.
A pile of debris has nothing. When water starts flowing over loose rock and soil, it takes some of that material with it. That cuts a small channel. More water goes into the channel, so it cuts deeper. Deeper channel, more water, faster cutting.
It runs away with itself.
Taiwan's agriculture ministry lists erosion from water flowing over the top as one of the most common ways natural dams fail. Huang Jing sheng, a resource engineering professor at National Cheng Kung University, explains the second part. Water soaking into the debris raises the pressure inside it and reduces the friction that is holding the whole blockage together.
So the barrier is being cut from above and weakened from within at the same time.
That is why the people whose job it is to be there have left.
China has suspended rescue operations near Gyirong land port. United Nations staff who were in Nuwakot have gone back to Kathmandu. The Red Cross said its teams are moving to safety and spreading the alert.

Nearly 600 dead and over 2400 missing.

This number has skyrocketed over the past 12 hours or so. I guess they've made it into some of the villages and seen how bad they are.

That wall of water and debris was moving in excess of 100mph at times.

But there were signs that were easy to ignore.
Look at the view upriver with a broad farmed plane to the left of the river and a small white house. Now look in the river at a large black almost perfectly rounded boulder in the middle of the river. And watch the water hit it.
You can see how smoothly the water is deflected as it hits that boulder.
To me it suggests that multiple floods have happened and eroded that boulder to that shape.
If that boulder was a basaltic volcanic neck, it would explain why the surrounding rocks are make that were different colored.

IF the flood waters don't drown you, collisions with the floating stuff will.
Do flotsam and jetsam apply to inland?

A bit from an Indian news outlet:
That's a new fear unlocked......trapped below ground in a tunnel that is blocked by no telling how many feet of mud, rock, and debris with the possibility of more flooding coming your way. If you're alive, I guess......
quote:
Around 933 workers across 13 hydropower projects in Nepal were reported missing after devastating floods in the Bhotekoshi River, according to the Independent Power Producers’ Association, Nepal (IPPAN). Of them, 254 have been rescued, while several others remain out of contact, with concerns that some workers may be trapped inside tunnels. The Upper Trishuli-1 project alone has 576 workers whose whereabouts remain unknown, out of around 1,350 employees. Rescue efforts have been hampered by damaged roads, disrupted communications and difficulties in deploying helicopters at project sites.

This is a school in Bairuni, Nepal, devastated by the catastrophic floods.
Around 700 children were in school when the disaster hit at about 10:30am. Teachers got them out and to safety.
School bags, lunch boxes, ID cards and water bottles are still sitting in the classrooms.
Just imagine the panic. One minute they're sitting in class, the next they're running for their lives. Those children are going to remember this for the rest of their lives.

An 8 year old boy ran from his school and climbed a tree to survive. This is a good piece from Reuters.
Moral of the story......let your kids climb trees every now and then. The practice may serve them well one day.
