				In many areas of the world, earthquakes cause buildings to fall and many lives to be lost. Civil engineers design structures to be able to withstand the force of earthquakes. To do this, they must understand how the movement of the Earth affects structures, and what types of materials are best to use in earthquake zone construction.
