The largest earthquake in history occurred in Chile (a magnitude 9.5 on May 22, 1960). The ground shaking is at a much slower rate than the structure’s natural oscillations, so that the behaviour is qua-si-static; the structure simply moves with the ground, with minimal internal deformation and its absolute displacement amplitude is approximately equal to the ground displacement amplitude. How is the strength of a earthquake … In general, ground shaking at sites less than 5 kilometers from the fault rupture would be twice as strong as that felt at 10 to 15 km away. Ground shaking near faults can also generate pulses that impose large displacement demands on structures. Its overall goal is to make such structures more resistant to earthquakes. A fracture in the earth's crust is called a joint. The seismic waves, which reach certain point at various instants of time, have different amplitudes and carry different levels energy.
