if you listen to the video, those are explosions. Deeper and somewhat muffled (as if they were underground). Fireworks sound different, and the big thing is that fireworks are visible. They explode in the sky. If they are too far away to be visible, they are also too far away to be that loud - you can't have it both ways. Plus, they never shake the ground unless you are very, very close to them (in which case, again, they would be visible).
Finally, a fireworks grande finale that lasts for 90 minutes? Nope. Those were explosions, partially muffled... So now the question is: DUMB's and tunnels in that area? I'm not sure what else this could be.
So... you really expect people to believe that was fireworks... lasting an hour and a half... "fireworks" so powerful they were shaking the ground? Yahshure - yubetcha. Your shill is showing...
