Just after 6 p.m. local time (15.00 UTC) on August 4, 2020, more than 2,750 tons worth of unsafely stored ammonium nitrate exploded in Lebanon’s port city of Beirut, killing around 200 people, making more than 300,000 temporarily homeless, and leaving a 140-meter-diameter crater in its wake. The blast is considered one of the most powerful non-nuclear, man-made explosions in human history.
