Answer:
Frequent shallow earthquakes
Explanation:
Shear is the response of a rock to deformation usually by compressive stress and forms particular textures.
During an earthquake when the earth shakes it produces a super shear earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave (S-wave) velocity.
The mechanisms of shearing depend on the pressure and temperature of the rock and on the rate of shear which the rock is subjected to.
