Any tsunami video I look at barely looks like a 20 feet wave hitting shore. But wikipedia tells me there have been dozens of 100+ feet tsunamis even in the last 10 years.

Because tsunamis are not the same in the movies as they are in real life,
Google ‘Japan tsunami’
It shows what it looks like on first impact, it just looks like water that rises and rises,
It isn’t some massive all of a sudden wave, it’s more like a big surge of water,
Tsunamis don’t look like a big tall wall that breaks over land.
Waves break (fall over forming a tube of air inside a tunnel of water) when the water depth equals 1.3 times the height of the wave.
So, a 6 foot tall wave at the beach will always break when the water depth is about 8 feet. And a 6 inch tall wave on the shore of a choppy lake will break when the water is about 8 inches deep.
The scale is always the same.
So a 100 foot tall rogue wave in the ocean breaks if the water depth is 130 feet.
There are very few areas with shorelines that drop that steeply away from land, so the tall waves always break further out to sea.
But just because a wave breaks, doesn’t mean that that water stops moving. It’s just not moving the way we picture big waves.
That entire volume of water still hits the shore and comes onto the land, but it does it laying down instead of standing up.
Tsunamis don’t have a massive wave front. The are low long waves that flow onto land and and slowly rise as they flow inland.
The real world osnt Hollywood, Tsunami don’t get that tall, at least not when they make landfall.
If you mean rogue waves instead (which are NOT tsunami) then there are videos of huge waves encountered at sea, its just that if most sea faring vessels simply wouldn’t survive a real wave that was literal hundreds of feet high.

Tsunamis tend to be very stretched out. They may start as huge walls of water, but once they travel across the entire ocean, there can be hundreds of kilometres between the front of the wave and its highest point, unlike the kinds of waves you see at the beach, which are usually only a few metres wide.
Basically if you watch a video of a tsunami, you’ll see the water rushes in and keeps rising for several minutes, less like a wave at the beach, and more like a sped up video of a rising tide. When they say that the tsunami was 100ft tall, they basically mean that this is how much the water rose by.
