Explosion of 800 tons rock

This is a film of a big explosion took place last week of a giant rock, which was part of the Ramon crater's cliff, in the Negev desert.
during the last winter a crack was discovered between the rock and the cliff and there was concern that eventually the rock might fall on the road below and endager the life of passengers.

25 explosive charges were used, which were planted inside the rock using drills.
the idea was to create a controlles explosion in order not to harm the clif of the Ramon's crater, which is a uniqe world nature phenomena.
