Across the ages, humans have tried to explain natural phenomena, like earthquakes, through stories and myths. Indian mythology says that when the elephant that holds the world on his back gets tired, an earthquake occurs; Norse mythology describes an earthquake as Loki, the God of mischief and strife, struggling to escape his prison; and Japaneses mythology talks about the giant catfish Namazu thrashing about beneath the earth, causing earthquakes.
