2000 tonnes is a lot. Two ships loading ammonium nitrate, the Grandcamp and the High Flyer, detonated in Texas City back in 1947. https://en.wikipedia.org/wiki/Texas_City_disaster https://en.wikipedia.org/wiki/Texas_City_disaster It says there was a 15 ft wave out into the Gulf of Mexico that lasted for almost 100 miles. And Texas City is not actually on the Gulf Coast, it is on Galveston Bay about a half hour away from the Gulf shore. And there is only a relatively narrow channel opening from the bay into the gulf. There are ton-sized pieces of shrapnel still in a few places across the town. I was stationed there in the early '80's when I was 20-something and everyone my age or older had parents & grandparents who had been through it, some surviving some not. Now it's been twice as many decades and it's not as present, elements of recovery come into reach that are not possible the first few years or decades.
