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.

    I'm going to assume that second photo was taken during the fire and before the explosion. Is the photographer even alive?

        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.

        Doesn't that image look odd? Or the ! marker looks out of place, shouldn't it be across the road on the other building, the one that is a big crater in the left most image. Something in that building across the road sure did go boom to leave the crater and rip a large section of the docks with it. The rest of them just look like they got blown away by the shockwave.

      In the post-explosion photo, the doors are closed. I'm guessing that the pre-explosion photos were taken well before, so the photos supply no evidence that the subjects or the photographer were in our out of the blast zone.

        There was also a video of the big boom from someone standing across the street. I didn't post the link because it's NSFW. No way that guy survived the shock wave.

      Maybe it was a good telephoto lens. Given that there was something like 25 seconds between the first huge cloud and the big boom, nobody close to the detonation probably would survive, even if they hopped in a car and raced away.
