For many years earthquakes have occu rred. That is why there argon earthquake pro! of buildings. The ability of a building to permit the stress of an earthquake depends upon its type of construction, shape, mass distribution, and rigidity. Different combinations argon used. Different shapes of buildings such as square, rectangular, and shell buildings can realize water earthquakes much better than skyscrapers.
