But what about the regular shape of the blast?
Looking at the videos of Tianjin disaster, there are multiple large explosions, each with a massive fireball, highly irregular, fiery projectiles flying everywhere etc.
The massive blast in Beirut was a singular event, with no preceding or subsequent blasts of similar magnitude. As if the ignition of the material was very efficient.
- beowulfey 6y agoHow many blasts from fire have you seen? How many blasts of AmNH4? If it’s more than 3, you may be able to form a trend of what to expect. But wait—-are you controlling all variables? Is every characteristic identical? Were they all open warehouses? The same amount of fuel? The same air humidity level? My point is, there’s no way to know what a characteristic explosion should look like, unless you are an explosives expert with hundreds of prior experiences. Also, I’d recommend taking the time to learn Bayes theorem. It’s currently also on the front page.
- ashtonkem 6y agoWhat you’re describing is the difference between a detonation and deflagration. Explosions are usually extremely regular in shape unless if obstructed in some way due to the way shock waves propagate in open air. And the Beirut explosion wasn’t just one detonation. There were two explosions, with a large fire and small detonations prior to the largest detonation. In all of the videos you can see a huge plume of smoke before the final detonation, as well as fire and smaller explosions if the video was close enough.
