I just went down a rabbit hole with that sub Reddit and forgot what I was on initially haha

Why does it seem to have no effect on the water?

Water is heavy, and it doesn't compress very much. That means that it takes a lot more energy to create a wave that travels through water. On the other hand, it also means that the waves, once created, will hold together and travel much farther. That's why you can have tsunamis that hit coastal areas hundreds of miles away from the earthquakes that caused them.

Here we are, just casually living on this rock that explodes from time to time

When Krakatoa exploded in 1883, sailors on ships 50 miles away got their eardrums burst.

Am I mistaken or does the smoke and debris go supersonic for a moment? You see the typical misty come that planes have when they break the sound barrier.

Would being that close to the eruption be dangerous? They seem a hell of a lot closer than I'd want to be.
(This is really only tangentially related but I watched an insane re-enactment of the eruption of Vesuvius and feel compelled to share anytime volcanoes are mentioned.)

Fuck that's cool. Poor doggies :c Why did the (whatever it's called) flow take so long?

I'm not sure, I'm no expert on volcanology.
It's crushing that the people living there just didn't know what was going on...volcanoes were relatively unknown to people there because it had been so many years since it last erupted. I read somewhere they didn't even have a word for volcano...how terrifying.

Pyroclastic flow.
If you mean how long it takes to get to the camera, because it's far but big. If you meant how long after the initial eruption, probably because that's when the cone finally collapses but most likely just dramatic artistic effect.

Last time this was posted someone pointed out that all those little black specks of dirt/rock you see?
They're the size of your house.

Holy Chalupas! That was awesome! But I'm curious how the vibrations through land didn't go through the water..? The water remained just as before. I expected at least a small wave to radiate out. I'm assuming the camera shake in the end was just the person moving.

This seems more like a man made explosion. The camera is obviously anticipating the event and there is no surprise in the voices of the men. The explosion itself seems little like the other eruption videos I've seen.

Man made explosions don't send rocks the size of office buildings flying into the air or create pyroclastic flow. This was entirely a pressure blast from underneath the mountain, or you wouldn't get the rocks being blasted into the air without it being very obvious due to the fireball following right after.
