Whenever an earthquake occurs, countless loss of lives and severe damages to the society follow suit. Since it is out of human power to prevent earthquakes, many different methods to predict earthquakes have been suggested instead of trying to reduce the damages. One way of predicting earthquakes is through observing animal behavior. It is a well-known fact that animals are far more intuitive than human beings, which is why an unusual change in animal behavior can be an indication of an earthquake. In fact, there are some records that prove so. There is a record from 373 B.C. Greece, which states that various animals such as rats, snakes, and weasels left their dwellings several days before an earthquake. Their sensory abilities may have reacted to the subtle changes in the environment before an earthquake. Another way of predicting earthquakes can be by headaches occurring in people. The presence of magnetite in the human brain makes this possible. Magnetite is a mineral that helps animals such as bats adjust to the electromagnetic field of the earth. This mineral can also enable human beings to notice the changes in the electromagnetic field by causing headaches before an earthquake. Finally, measuring radon emissions can also be a way to predict earthquakes. Most rocks release small amounts of gases whenever a seismic change occurs. One of these gases is radon, and it can be easily detected as the gas is radioactive. Since earthquakes are caused by seismic waves, it can be said that a high concentration of radon in an area can be a sign of an earthquake.
