Scientists believe that most animals survived the 2004 Asian Tsunami because they had perceived its coming and they prepared for it. It is believed that animals can hear and perceive infrasonic sound and Rayleigh waves which are usually the warming signs of a coming tsunami. Scientists believed that the animals felt the shaking of the ground as a result of the Rayleigh waves and hear the infrasonic sounds which can not be heard by humans. This makes the animals to flee to higher grounds [above sea level] for safety.
