Natural disasters are difficult to predict, and till date many scientists continue to look for fool-proof measures that can predict these happening. While there are no obvious tell tale signs of a major earthquake going to occur, these few indications have been noted from time to time.
Sign one: Unusual behavior of animals
Animals like snakes, rats, dogs etc. have been noted to behave differently before a massive earthquake occurs. Various accounts of such anticipation by animals have been noted through history. Many believe that animals can feel the earth vibrating before humans do. Others also believe that animals can detect the gas released by the earth or electrical charges in the air before a large earthquake. However what animals exactly react to continues to remain a mystery and a topic of study for many researchers.
Sign two: Foreshocks
Many large earthquakes are often preceded by small tremors often known as ‘foreshocks’. While these small tremors can mean nothing more, and can end with tremors, they may predict that a larger earthquake is coming. People are thus advised to become prepared at such a time, that a bigger earthquake may come.
Sign three: Usage of scientific seismographs
Seismographs are instruments that record the motion of the ground during an earthquake. These systems are installed underground and are connected to other such systems across the world as part of a seismographic network. These instruments record the shaking of the ground on to a graph and scientists can use this to predict when and how large the next earthquake will be.
Sign four: Predictions by ‘sensitives’
Many people, termed as ‘sensitive’ are noted to have definite symptoms before earthquakes are about to occur. These include migraine attacks, inner ear tones or screeching sounds. These symptoms are also noted to disappear after the earthquake passes by. While this has been noted in some people, it is still difficult to predict the epicenter of earthquakes or the exact date and time. Various sensitives are now trying to coordinate their symptoms, to predict this.
Sign five: Eruption of a volcano
Volcanic activity in a region can also put pressure on the underlying tectonic plates, further leading to an earthquake. Few experts also believe that as it is easier to predict volcanoes than predict earthquakes, data from the former could help gather information for the latter.
Earthquakes are a natural disaster and continue to be difficult to predict. While many scientists continue their work on prediction of this natural disaster, readings are not always accurate, and are more of an educated guesswork than anything else. It is thus in the best interest of people to be prepared for such a disaster. However with continued efforts, one day this will surely be made possible. And then, many lives and societies will be saved from the horrific effects of these disasters.
