Bhopal by the Sea!
LOL No... it will be NOTHING like Bhopal. That was a cyanide event that killed 8,000 people in a highly densely populated area.
This will be a VERY short-term “big bang”, that will damage buildings within a half-mile, maybe break some windows a little farther.
No people should be killed.... unless they are REALLY stupid.. or, super-brave (ie: killed while trying to stop it)
