Earthquakes cannot be prevented and are rarely predicted correctly. The scientists who study and work on earthquake facts are still working on a system that might correctly predict earthquakes. The effects of earthquakes can be reduced by looking at the geological history of a place and seeing if it has suffered from such types of events before.
Looking at these historical facts allows people in the area to build structures that can withstand the sometimes devastating impact of an earthquake. These earthquake-resistant structures are generally used in hospitals, schools or other places where large masses of people may be gathered and unable to get to safety. The buildings can take a large amount of shaking with minimal damage.
