For the Nuclear accident, is it Chernobyl? If yes, could you provide the source you used ? (because there are many different sources for Chernobyl deaths)

What about dam failures? That's different from a natural flood, right?

According to other comment by op, they counted Banqiao dams accident as structural collapse.

Correct. However, I've just realized thanks to the link from u/denisrennes that the 1975 Banqiao Dam failure article gives an upper estimate of 240,000 deaths while the List of Accidents and Disasters by Death Toll page listed a single 171,000 figure. I use the past tense here because I just edited the page with a correction.

Regardless, the visualization rounds all figures (as stated in the image and my top-level comment) so both 171,000 and 240,000 would result in the same 2 squares being shown.

Looks like the 1957 Mayak disaster.

Possible but difficult to say because the figures were hidden by the USSR at the time. However, some of the figures given for Chernobyl by some sources seem closer.

Sorry, neighbor, I wasn't clear: the deadliest radiation disaster listed in the Wikipedia list OP used as a source is the 1957 Mayak storage tank explosion. Chernobyl is third on that list

u/tremynci is correct: the source (listed in the visualization and my top-level comment) has the 1957 Mayak nuclear waste storage tank explosion as the all-time deadliest nuclear disaster with 200-6,000 deaths. I took the high end of this estimate (also mentioned in the visualization and my top-level comment).

Chernobyl is listed by the source as having a high end estimate of "4000+" with the note:

>Far higher death toll estimates have been made, but are disputed.

I took the Mayak disaster rather than going with disputed figures.
