Ammonium nitrate: what is the chemical blamed for blast in Lebanese capital?

The likely cause of the huge blast in Beirut on Tuesday appears to have been the highly reactive chemical ammonium nitrate.

Lebanon's prime minister, Hassan Diab, said 2,700 tonnes of ammonium nitrate exploded after lying unsecured in a warehouse for six years, tallying with reports that a ship carrying a similar quantity of the chemical had unloaded its cargo at the port in 2013. It remains unclear what caused the chemical to ignite.

Ammonium nitrate.

Beirut explosion: over half the city damaged in blast that killed at least 100 and wounded 4,000 – live updates

AFP is quoting the governor of Beirut, Marwan Abboud, as saying the damage from the port blast has extended over half of the city, with the cost of damage likely above $3bn.

He has also upped his previous estimate of the number of "homeless" to 300,000, which is close to the total population of the central part of the capital. Again, we are not sure if he is talking about homelessness or people whose homes have been damaged.

    It looks like that taller building in the center may have prevented the blast wave from being even worse.

    Little Boy detonated at 580 meters above Hiroshima, Fat Man at ~503 meters above Nagasaki, but off-target:

    https://en.wikipedia.org/wiki/Atomic_bombings_of_Hiroshima_and_Nagasaki [wikipedia.org]

    At 11:01, a last-minute break in the clouds over Nagasaki allowed Bockscar's bombardier, Captain Kermit Beahan, to visually sight the target as ordered. The Fat Man weapon, containing a core of about 5 kg (11 lb) of plutonium, was dropped over the city's industrial valley. It exploded 47 seconds later at 1,650 ± 33 ft (503 ± 10 m), above a tennis court, halfway between the Mitsubishi Steel and Arms Works in the south and the Nagasaki Arsenal in the north. This was nearly 3 km (1.9 mi) northwest of the planned hypocenter; the blast was confined to the Urakami Valley and a major portion of the city was protected by the intervening hills. The resulting explosion released the equivalent energy of 21 ± 2 kt (87.9 ± 8.4 TJ). Big Stink spotted the explosion from a hundred miles away, and flew over to observe.

    The ground location of the Beirut explosion limited the damage somewhat, and that tall building next to the warehouse could have prevented hundreds of additional deaths by soaking up a lot of the energy.
