Here's the Analysis of the footages of Beirut Explosion ( Blast ) and video footages.
About 2,750 tonnes of ammonium nitrate were stored in the Beirut port warehouse that exploded Tuesday, devastating large parts of the Lebanese capital.
The devastating explosion at a port in Beirut yesterday evening (Aug. 4) that killed more than 100 people and injured at least 4,000 seems to have stemmed from a storage unit housing enormous amounts of ammonium nitrate, according to news reports.
The initial explosion ignited a fire, while the second painted the sky in an apocalyptic mushroom cloud and sent a shock wave rippling across the city, leveling buildings and wounding thousands.
The scale of the damage from the epicentre of the explosion at the port of Beirut to the windows blown out kilometres (miles) away resembles other blasts involving the chemical compound commonly used as an agricultural fertilizer.
But the compound itself typically doesn’t detonate on its own and requires another ignition source. That likely came from a fire that engulfed what initially appeared to be fireworks that were stored at the port.
Online videos of the disaster’s initial moments show sparks and lights inside the smoke rising from the blaze, just prior to the massive blast ( Explosion ).
