Having read Simon Winchesters book on Krakatoa, I don’t think it was the initial blast that was the big one. It took several days to build up to the final super blast that disappeared the entire mountain. It did cause a tidal wave that sent a tsunama up over 100 feet into a bay nearby. See the movie some time.
In the video, at first the bison seemed to be walking, but those at the tail end were running.
Again, a supereruption is not all that super. A minor quake with a landslide tops it.

The 3 major eruptions of Yellowstone in the last 2 million years were pretty darn large. The megatsunami you linked was a unique product of the tsunami being compressed into a narrow fiord. The super eruption of Toba 74,000 years ago triggered a noticeable downturn in temperature if you look at long term temperature charts.
That’s been claimed, but the fact is, the effects (and magnitude) of old volcanic eruptions has been systematically exaggerated over the past 25 years or so, ever since the Alvarez model began to gain acceptance. The steady drumbeat of denial of the model is mostly found in the UK, with a few eastern seaboard academics. Dewey McLean used to have a website where he claimed he’d been so upset by supposed threats from Luis Alvarez that he’d had to retire, but the facts are otherwise.
Not long ago the date of the (imaginary) supereruption of Thera was moved forward in time, and just this past week someone reiterated the claim that the Tempest Stele records the eruption and then used the 17th c date to try to push back the dating of Pharaoh Ahmose.
