Beirut Explosion in Slow Motion, 2 angles (4 Aug 2020)

This has nothing to do with space, so please forgive me.
Earlier today there was a huge explosion in Beirut, Lebanon near the harbor which produced a dramatic shockwave, destroyed nearby buildings, killed an at least 73 people, and injured at least 3000. The loss of life and injuries are a great tragedy. Our thoughts go out to those who were lost, those who lost loved ones, and those who face a long road of recovery.
Here's a breakdown of what this slow-motion video of the explosion from 2 different angles shows:
- The initial fire at the fireworks warehouse, with billowing gray smoke.
- A series of white flashes which appear to be either fireworks, or electrical sparks (blown transformers).
- The massive explosion of 2750 tons of ammonium nitrate with an orange fireball, which threw up a towering cloud of red smoke (the color is due to the ignited ammonium).
- A rapidly-expanding white "puffball", which is actually just water vapor in the air being condensed into clouds by the shockwave.
- The roofs of builds near the explosion being ripped off as the shockwave hits them.
- In the second angle we see the shockwave propagating across the water.

What happened:
The initial fire was in a fireworks warehouse (notice the white flashes), which then spread to a huge stockpile of 2750 tons of highly explosive ammonium nitrate (used in fertilizers and explosives) that had been seized from a ship back in 2013, and stored unsafely in the Beirut harbor ever since (terrible mistake). For a sense of scale, the huge 2015 explosion in Tianjen, China involved just 800 tons of ammonium nitrate. Ammonium nitrate has 42% the explosive power of TNT, so the equivalent yield of the Beirut blast was 1155 tons or 1.2 kilotons of TNT. That's 7.7% of Hiroshima.
The gray smoke is from the fireworks factory fire. The giant plume of red smoke is from the ignited ammonium nitrate. The white cloud is caused by the supersonic shockwave compressing the air and condensing the atmospheric humidity into clouds as it expands. After the shockwave passes, the air decompresses and the clouds become invisible water vapor again. The same thing happens in the wake of a supersonic jet fighter, if the atmospheric conditions are right. In arid regions, you don't see [as much] white condensation from shockwaves (see "Pepcon explosion").

A note on why I posted this video here. I've done a lot of slow motion processing of videos from space, rocket launches, and SpaceX Starship explosions. So, I applied the same slow motion processing to these clips of the Beirut explosion, since I didn't see any other slo-mo renders out there and I thought people would want to see. Slow motion - even if it's just interpolated from a regular-framerate video, gives your brain more time to process what it's seeing. You can catch details that you otherwise would have missed.

DON'T BE A CONSPIRACY THEORIST! People are saying that it was a missile, or a bomb, or an alien death ray... they seem to enjoy latching on to any theory that isn't actually supported by the facts.

- False claim: "This was a missile! A thermal video I saw proves it." WRONG! Those "missile" videos were poorly-done and obvious fakes done by someone who wanted to score fake Internet points by stirring up people's emotions. The supposed "infrared"/"FLIR"/"thermal" video was just a regular video whose colors were inverted. Anyone can do this in moments using video editing software. Furthermore, it didn't look anything like actual infrared imagery. The "missile" claim is totally fake news; completely made up and false. Don't propagate the lie. Some links:

- False claim: "This explosion must have been a nuke because it was so different from the 2015 explosion in Tianjen, China." WRONG. The difference was caused by the amount of explosive material involved, and the location. Tianjen 2015 was caused by 800 tons of ammonium nitrate, more than a mile from the water. Beirut was caused by *2750* tons of ammonium nitrate (more than 3x as much), right on the water's edge.

Furthermore, if it had been a nuke, 1) there wouldn't have been a reddish smoke plume, 2) the explosive power would have been MUCH more (Hiroshima was about 7.7x as powerful as the Beirut blast, and that was a *small* nuke), and 3) there would be radiation.
