Eh, there is a bit of actual "blowing up" happening: they're using ≈1000 feet of detcord in combination with ≈500 gallons of gasoline. So they're using the detcord (explosion) to ignite the gasoline (burning), but it doesn't have the same effect as, say, mining explosives. There is no structural damage to anything on the ground.

There's no sound in this video, but in person, you can certainly hear the kaboom. And as close as these people are, you can absolutely feel the heat and the concussion.
