Blasting causes vibrations just like earthquakes and create P-waves (Primary waves) that push and pull the earth. S-waves (Secondary waves) shake the earth from side to side. These waves cause disintegration in earth and damage to structures standing on the ground, said sources in the archaeology department.
‘Structural remains of sites of Taxila valley are of very fragile nature and easily vulnerable against such destructive forces,’ they added.
