There are many natural disasters that can be very dangerous. Floods, earthquakes, landslides, tornadoes, volcano eruptions bring death and destruction. In my opinion the most dangerous is earthquake. First of all it always takes place unexpectedly. All other disasters can be more or less predicted. Earthquakes always strike unexpectedly. There is no escape because people have very little time to leave their homes. Very many people die under debri of their houses. Many others die of heart attacks. During earthquakes a lot of other dangerous situation may take place. Fires can start or gas pipes explode. Electricity can also cause a lot of problems at this time. Also big areas are usually hit by earthquakes so it may take a lot of time before help arrives from the safe areas. Earthquakes can also destroy industrial plants, including power stations and nuclear power stations. In this case the number of victims of floods and radiation can significantly increase.
