When you blow up a quarry that’s 65 feet high with 75 tons of explosives, you turn the rock wall into a tsunami wave that sends nearly 400,000 tons of rocks flying everywhere. The blast of the Bremanger Quarry in Norway looks great because it was carefully planned, with explosives planted in 454 blast holes made along the 1260-foot long rock wall.
