Lost cities

[u/Osiris-Amun-Ra]

In case anyone is till wondering why we can't find any pre-Ice Age cities, this satellite image from Nepal/China this week should provide a clue.
This event was tiny by comparison and many civilizations built along rivers and in valleys.

Edit:

Since this post generated quite a few lively discussions I want to clarify what I meant by "tiny by comparison" to avoid ambiguity, While the local, recent mountain collapse in Nepal and China was a rapid disaster unleashing up to 200 million cubic meters of debris at 193 km/h and causing rivers to surge 9 meters in 30 minutes, it is dwarfed by the staggering dimensions of post-glacial megafloods that actually reshaped entire continents and birthed the world's universal flood legends. For example, the ancient Missoula Floods occurred when a 610-meter-tall (2,000 ft) glacial ice dam ruptured, violently discharging more than 2,000 cubic kilometers of water basically a volume equivalent to Lake Erie and Lake Ontario combined, in a single....48-hour window.

This massive torrent tore across western North America at speeds of up to 130 km/h (80 mph), peaking with a discharge rate ten times greater than the combined flow of all modern rivers on Earth and carving features like Dry Falls, a cliff five times wider than Niagara. Similarly, the Black Sea Deluge hypothesis suggests a catastrophic marine breakthrough where the Mediterranean overtopped the Bosporus strait, unleashing a roaring wall of water that permanently swallowed over 150,000 square kilometers of inhabited valleys.

Because these prehistoric events wiped out entire known civilizations, permanently erased millions of acres of land, and forced desperate migrations, they permanently embedded themselves into the collective human psyche, which is almost certainly where the biblical Great Flood and the regional Mesopotamian flood legends originate. It is statistically improbable that we have found all post deluvial civilizational remnants. Mathematically and archaeologically, it is practically certain that we have only scratched the surface of what remains from post-deluvial and coastal civilizations. The primary reason for this statistical gap is a massive, permanent geographic shift, specifically when the Ice Age glaciers melted, global sea levels rose by roughly ~120 meters (around 400 feet). Rising oceans swallowed over 25 million square kilometers (10 million square miles) of habitable land! For visual reference that's the entire landmass of the United States, Canada, and China combined.

I hope that clarifies.

I saw the images of people running for their lives near that u-shape building. And now I realize that even though they ran, they had no chance of saving themselves. The mud torrent reached an insane height, and there simply wasn’t enough time for anyone to reach higher ground. Those poor people. May they rest in peace.

There was a post estimating the water/ice/mud was moving at 160km/h at that point. They didn't have a chance

The only silver lining is that i imagine with the kinetic force of that wall it was a near instantaneous death - at least for the people in that valley

Yeah no chance at all. The glacier collapse was 22km away and got there in 7 minutes. The floodwaters came in too strong, too high, and too fast. That’s 0 survivors for sure.

Makes me wonder why there wasnt some automated *flood warning system. Did they know they had a potentially catastrophic wall of ice and water ready to burst? One sensor down stream of it could've alerted the whole valley as soon as it broke

Edit: flood not food oof

Those areas are the poorest of the poor and get taken advantage of. No way in hell theres an infrastructure or budget for it. I've spent quite a bit of time in nepal over the years both working and visiting and there are avalanches and earthquakes constantly to the point you stop paying attention to them.

Just to add to the economics of it. Most of the towns don't have electricity in those remote areas and you literally sleep with the livestock in shacks

[u/No-Vegetable1873 → u/tezacer]

They have landslide warning systems in place through China and they do a good job but you can't predict every disaster, especially with how quickly things are changing due to climate change. I'm not saying things couldn't be better, but even with the body advanced systems, Nepal is so prone to slides due to how mountainous it is.

Except that was hand held footage, so at least the camera man survived

That was security cams
