How animals use infrasound to avoid disasters
Animals have been known to perceive the infrasonic waves going through the Earth by natural disasters and can use these as an early warning!
A recent example of this is the 2004 Indian Ocean earthquake and tsunami.
Animals were reported to flee the area long before the actual tsunami hit the shores of Asia.
According to eyewitness accounts, the following events happened:
1) Elephants screamed and ran for higher ground.
2) Dogs refused to go outdoors.
3) Flamingos abandoned their low-lying breeding areas.
4) Zoo animals rushed into their shelters and could not be enticed to come back out.
Relatively few animals have been reported dead, however, reviving speculation that animals somehow sense impending disaster.
However, some have suggested that it was the influence of electromagnetic waves, and not of infrasonic waves, that prompted these animals to flee.
Sixth sense? Know in advance when the earth is going to shake?
Or animals just have more acute hearing?
