you could make your point without being derisive and ableist, especially considering the people involved have credentials and are trained in their fields.

But it creates "engagement" which is rewarded these days apparently.

Also, I thought the trained people should have learned a thing or two from Pompei not to build near volcanoes. I'll cut some slack for the people who designed Pompei, they didn't know, but everyone after that should have learned.

Tonga eruption as if it had* happened in various nations

Edited, thanks a lot for the correction! English is not my first language!

just so you know, you are correct to call Florida and California "states."

This looks like a tedious process that I would have totally done on my own had I thought of it. By that I mean the painstaking process of matting out each frame, then randomly placing it on places of the map, just because I could, just for the lulz. I'm not discounting it as "i could have thought of that", but appreciation for how useful it actually is. Some people cannot grasp certain things without visuals, and thi…

FWIW:

* I think visuals are great for illumination overall, some people not withstanding :)

* I think they also used semi-transparent shadow

How about this tool?

Granted, it's the Evergiven, but how hard would it be to exchange the image?

For western US trained geoscientists, the Bishop Tuff [1] (from the ~750,000 years ago eruption of the Long Valley Caldera, near Mammoth Mtn. in California) is a "modern" comparable ashfall deposit. This was quite a bit larger (edited to add: I meant in areal extent, not necc. volume erupted). [1] https://en.wikipedia.org/wiki/Bishop_Tuff

> I mean, how fucking dumb do you need to be to look at a lava flow and cut a road or train track through it? Do they not realize that lava means "run"? Build infrastructure elsewhere.

Right, and nobody should build cities on rivers or coasts, because rivers flood[1] and coasts get hurricanes that cause floods, nobody should build anything in valleys[1], because they flood, nobody should ever build anything in mountains, because they get avalanches and mudslides[1], nobody should build anything on the Ring of Fire, because earthquakes, and the midwest should be uninhabited because tornadoes.

If someone built a two-lane road that cuts through an old lava flow, maybe those people aren't the idiots. Maybe they've done the math, and determined that the cost of going around it is going to be greater than the risk of eruption * cost of dealing with the consequences.

[1] Stupid Canadians[2], building a highway through a valley, and some mountains. If only someone with some common sense would have come in and told them that this was a bad idea! https://en.wikipedia.org/wiki/November_2021_Pacific_Northwes...

[2] Now they don't have a highway! https://www.nanaimobulletin.com/news/aerial-video-of-coquiha...

I don’t understand. Literally all of Hawaii is built on top of lava flows. Are Hawaiians dumb idiots for building roads and other infrastructure on top of lava flows?

I'm assuming you meant to write ableist, in which case, how is the above comment ableist?

> And then you have idiots that build train tracks and highways right through lava

I was disappointed to see no active lava flows in your linked image. What you show is simply a road and train tracks built on top of rocks.
