NASA: Tonga blast was 10 megatons, more powerful than a nuclear bomb

Hurricane Katrina was quite recent, it devastated a major American city and had all sorts of bad effects in lots of places, people have an intuitive understanding of how big Hurricane Katrina was - be aware of course that intuitive understandings are not precise.

Hurricane Katrina made very little damage directly, as an effect of the energy of the wind. Almost all the damage was caused by the flood, which in turn turn was a consequence of the levees failing.

It doesn’t make much sense to compare the energy released by Katrina to that of the Tonga eruption.

The math might check out but that's about it. Comparing a storm to an explosion is completely asinine because the mechanism by which the energy is dispensed is completely different.

Katrina did squat to the city except tear up some roofs and windows. The water deposited just so happened to breach some flood control stuff and then all the damage was a result of everything being immersed in floodwater. A storm releases energy in the form of find and droplets of liquid being accelerated by gravity and flung around by said wind. An explosion releases a pressure wave.

Comparing energy released in storms to explosions is like saying a leafblower can push harder than a dude with a sledge because it has more horsepower. Neither comparison serves any useful purpose.

As a non-American, I have no idea what kind of damage hurricane Katrina did. As far as I am concerned, there was some wind. Enough to make international news, but that's about it.

But when I see "comparable to a nuke" at least I know immediately that this is a major event. A hurricane, powerful as it may be, is harder to grasp for a comparison.

As a non-American, I do.

I agree comparable to a nuke is better, I was just commenting that Katrina for a large number of people is quite different than the other examples and does convey an intuitive understanding.

While noting that intuitive understandings are imprecise.
