Why do the animals behave in a peculiar manner before an earthquake?
When the earth quakes, they produce low frequency infrasound before the main shock waves. These infrasonic waves are not audible to the human ears. But animals are able to detect these waves and hence some animals get disturbed before earthquakes and start behaving in a different manner.
