This 2-ton anchor was thrown more than 1.6 miles when the Grandcamp exploded. (Texas City 1947 disaster - about 2300 tons of amm nit.)
In April of 1947, I was in the 4th grade in Webster, Texas -- and the shock wave from the Grandcamp explosion knocked art supplies off of our desks. While I was picking my stuff up, lots of kids ran to the windows, saw the mushroom cloud, and shouted, "An A-Bomb!"
I took one look at the orange cloud, (which looked like the fumes in the top of a nitric acid bottle) and, said, "Nope -- that's a chemical explosion. Probably at the Monsanto plant..."
Soon the smoke turned dark brown, then black -- so, it was obvious that some of the oil refineries and/or tank farms were involved.
The school shut down and bussed us all home -- to clear the narrow Old Galveston Highway for emergency traffic.

So -- as soon as I saw that reddish-orange smoke column in Beirut, photos, I knew, "Ammonium Nitrate!"
Texas City was a big one: 2.3 KT of AN -- and Beirut was bigger: 2.75 KT.
As you posted, much of the damage/death in TC was from shrapnel -- or whole slabs of 1" thick ship hull plating... Plus, the whole industrial end of town was one big firebomb -- waiting to blow... Worse, with the exception of one man who was on vacation, the Grandcamp blast wiped out all the firemen and equipment of the Texas City Fire Department...
