Nature of seismic loads
During an earthquake, the sudden release of deformation energy, accumulated in the rocks by the relative movements of the different parts of the earth's crust (the lithospheric plates), gives rise to seismic waves that propagate and reach the surface of the ground, setting it into vibration.
These ground movements...
