There is still a spectacular tonnage of ordnance on board the wreck of a Liberty ship sunk just off Gravesend. It was deemed too dangerous to move it during the War, and it must be far more unstable now...
Re largest explosion, I remember reading about a US military experiment to replicate a nuclear sized blast using conventional explosives back in the early '50s. I recall this to have been approaching half a (real) megaton, and for some reason think it might have been in the arctic somewhere. Any memories jogged?
And a couple of minutes on Google shows a 4000+ ton demolition job on German defenses in Helgoland in 1947, so the Tatenhill event was probably only UK's biggest.
