Video: When you blow up a quarry that's 20m high with 68 tonnes of explosives, you turn the rock wall into a tsunami wave that sends nearly 363,000 tonnes 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 384m long rock wall. One perfectly timed boom and the wall falls down all at once. Check out Norway's largest quarry blast ever in the footage filmed by Kal Jonny Thue Venøy below. At the end of the video, you can see the rocks that were created because of the explosion.
