Yeah that was quite big I'd say. Do fireworks create a cloud like that? I remember a firework warehouse video from Mexico (I think) years ago and, though it was a big explosion, you could still at least see fireworks going off. That just seemed like a big explosion.
Edit: As I was, I can see some fireworks I suppose, but that second blast was massive still.
Unofficial word from amongst my tribe is that there was a boat with fireworks on board. There’s one video out there where you can see it cooking off. On my phone, I was quite skeptical of that, but on a different screen I could see it better.
Anyway, that boat caught on fire. Not good. That right there is already what I’d call a bad fucking day. That boat just happened to be located right next to a warehouse where a fuckton of confiscated chemicals and explosives (sodium nitrate and possibly AN) were kept for a couple of years ( let that sink in for a second...)
The grain silo @medicchick references is right beside that warehouse,, but I digress.
So yeah, fireworks on fire get fucking hot as balls. That shit also gets verrrrrrrry touchy. Word from witnesses was that there was a smaller det before that big motherfucker. That would be the fireworks. Heat, shock and friction were adequately applied to that warehouse chock full of really touchy shit as a result. The end result is Exhibit A.
