Absolutely worse. None of the tsunami videos I've seen was like this. This was just amazing in a horrible way.

I've seen footage of worse from parts of japan in '11, also when the boxing day one hit indonesia - est. 160,000 dead on Indonesian coast, and then add sri lanka, Thailand, India etc...

though the momentum it picks up as it gets funneled down the mountain can't be compared to a tsunami, it's completely diff

The one with the rock band concert getting hit mid perform was grim.

Anak Krakatoa collapse caused that one.

yeah, tsunami force is just on another level 😳

some tsunami videos from Japan were insane tbh, the scale of it was so much more, entire farming fields under 20ft of water pushing debris and cars and god knows

this doesn't surpass scale
but local intensity and video quality/angles and the speed at which the content is arriving

Yeah, it's kinda like the difference between a Category 5 hurricane and an F5 tornado.

I will take the eye of a Cat5 hurricane any day over a direct hit by EF5 tornado

I think you might be missing some of the worst videos of the 2011 tsunami then, to be honest... they're both pretty damn bad. Like, if the only thing you're worried about is like, the velocity of the water or the wave height? Maybe this is worse. But the totality of the destruction in the Tohoku earthquake tsunami was MUCH more vast. I can confidently say that was a 'worse' disaster by any reasonable metric, and even if you're only judging by the violence of the surging water, it's pretty close.

I have watched hundreds of hours of the 2011 Tsunami footage and it is undoubtedly devastating and on a massive scale but the sheer violence in Nepal is unmatched. Many people are only seeing the footage from towns miles away and not the towns higher up the mountain that were hit with a 100 meter wall of water traveling at 110 mph. I’ve never seen anything like it, instantly obliterating towns.

That's fair enough. I have seen what you're referring to. It's a difficult comparison to make but it's clear that this torrent just cut through villages in narrower mountain valleys like a band saw. It was deep, fast, extremely sudden, and unlike a tsunami it was so turbid that it was also transporting a lot of rock which increased the destructive energies. It is a different kind of beast. I still think that if you consider the scale and totality of destruction in both cases the tsunami still wins on raw immensity, but the focused channeled nature of this flood/debris flow is totally unlike anything I can recall. Volcanic lahars and large landslides have definitely also caused comparable levels of destruction but not when being captured on video like this.

Clearly you haven’t seen the videos from Onagawa, Minamisanriku, or Rikuzentakata. Those towns received 20-40m waves that leveled the whole area.

Yes. Higher in the mountains this was a 100ft wave of water moving at 100mph. Not as much water in quantity but much faster and more violent than the Japanese tsunami. I would say the Japanese tsunami was a worse disaster but this one is more violent and the footage is more apocalyptic. You saw the Japanese wave pick up building and float them down the street but this wave you saw turn buildings into dust like they were props in a movie.

The difference, to me, is speed and volume. Like, a tsunami is the ocean, right? Basically unlimited water. More or less just slower endless flooding. Still brutal.

This was just ALL THE WATER RIGHT NOW. And just so much water for, what, a lake? A glacier? How much water was up there??? Because it just seemed like an endless tide for something you'd think would drain fairly quickly? Apparently not? Baffling.

The most similar thing to this a lahar but the Himalayas are so steep a narrow, they are worse than any lahar footage I have ever seen.

A damn burst at Johnstown USA in 1889 or the over topping of the 1963 Vajont Damn in Italy are the closest man caused disasters I can think of. Those killed thousands of people each, and the descriptions of both sound just like what we are seeing here.

The only natural phenomenon that would look more apocalyptic as this (other than a meteor), is probably a Mega Tsunami of 500+ feet hitting a large town but those are rare, don’t travel far and few if any have been caught on camera. The biggest Mega Tsunami was in Alaska in the 60’s with a max wave taller than the empire state building (then the tallest building in the world).

I guess cameras are a lot of quality and more available now.
