00:00animals may have a sixth sense and no, they don't see dead people, but it may help them sense
00:10when earthquakes will strike. An international research team placed sensors on six cows, five
00:15sheep and two dogs on a farm in Italy in an earthquake-prone area. They studied their
00:20movement over several months and found they were unusually restless up to 20 hours before
00:26earthquakes. Animals closer to the quakes at the center started behaving unusually earlier
00:31than those that weren't. Though the team says it's still unclear how their sixth sense works,
00:36they have a few ideas. Researchers think they may be able to sense earthquakes by picking up the air's
00:42ionization caused by large rock pressures in earthquake zones with their fur. Or it's possible
00:48animals can smell gases released from quartz crystals before an earthquake. Today, predicting when and
00:54where earthquakes will happen is still a challenge. Researchers say studying a big number of
00:58animals in different regions around the world could provide further clues. A study was published
01:03in the Ethology International Journal of Behavioral Biology.
