How did quarry blasting cause damage to my property? Quarries use explosives to break rock, but some of the energy escapes during the blast. Some of that energy escapes into the atmosphere to generate airblasts or air vibrations, while the remainder of the energy leaves the blast site through the surface soil and limestone in the form of ground vibrations.
