Supposedly the tank contained 6 tons of explosive. No idea what type, but here is some googled info on what 1 ton can do….
Even given perfect intelligence and accuracy, most guided weapons in the 500- to 2000-lb range are sufficiently powerful to routinely cause some degree of collateral damage. This, because they carry hundreds of pounds of enhanced high-explosives wrapped in hundreds of pounds of steel – an obvious point, but one that has been too often occluded or overlooked.
A 2,000-lb bomb typically contains 945 pounds of tritonal, a TNT derivative that is about 20 percent more powerful than TNT. By comparison, the bomb that destroyed the Murrah Federal Building in Oklahoma City on 19 April 1995, comprised approximately 5,000 pounds of ammonia nitrate mixed with fuel oil — the equivalent of nearly 4,000 pounds of TNT. The portable devices used by suicide bombers typically weigh between 10 and 35 pounds; these can carry a punch equivalent to 40 pounds of TNT if a plastic explosive (C-4) is used.
Most everything will be severely damaged, injured, destroyed, or killed within 20 meters of a 500-lb bomb blast and 35 meters of a 2000-lb blast. This lethal radius can be partly mitigated by detonation inside a large, compartmentalized building – however, as a Rand study points out: “While structures surely have some shielding effect, building collapse and spalling are secondary yet major causes of injury.” (pdf)
Averaged across different types of surfaces, a 2000-lb bomb will carve a crater 50 feet across and 16 feet deep; a 500-lb bomb will carve one 25 feet across and 8.5 feet deep. The probability of incapacitating injury to unprotected troops within 100 meters of a 2000-lb bomb blast in the open is 83 percent; for those between 100 and 200 meters it is 55 percent. (pdf)
Safe distances for unprotected troops are approximately 1,000 meters for 2000-lb bombs and 500 meters for 500-lb ones. Even protected troops are not entirely safe within 240 meters of a 2,000-lb bomb or 220 meters of a 500-lb bomb. [For sources and more information on blast effects see the note at bottom.]
