5. Animals "extra sense": comment from Jessika Toothman :
"The most critical sense is hearing. There are some sounds people can't hear. On the low end of the scale are infrasonics, low-pitched sound vibrations on the hertz frequency scale falling below 20 hertz (Hz). On the other end are high-pitched sounds, like dog whistles, which humans also can't hear. People typically hear in a range between 20 and 20,000 Hz (middle-aged adults usually don't hear beyond 12,000 or 14,000 Hz). Elephants, however, generally hear between 16 and 12,000 Hz. Cattle also start hearing sound at 16 Hz, but can continue to hear all the way to 40,000 Hz. And what sort of elements produce sounds in the infrasonic range? The answer includes earthquake shockwaves and ocean waves. See where this is going?

Some researchers think certain animals, like elephants, get an early earthquake warning because they can sense shockwaves in the ground through their large feet. They don't hear the sound and think, "Oh no, an earthquake is coming." But they do sense distant, unfamiliar vibrations rolling in that terrify them into fleeing for safety.

How animals, not just elephants, sense these vibrations is generally unknown. Researchers are examining different organs, body parts and nerve chains in a variety of species that may be able to pick up sound vibrations that humans just can't sense.

This theory could also account for the just-in-time-reactions of other animals with less acute hearing just prior to the tsunami. Researchers note that infrasonic sound produces uneasiness and nausea in people. Animals may perceive these sound vibrations as dangerous and instinctively seek safety."

6. Dan Martin reported in the age.au, May 2008, "Chinese media reports and internet blogs have buzzed with reports of mass migrations of thousands of frogs and toads near the quake region in Sichuan province just before the May 12(2008) disaster, which left more than 80,000 people dead or missing.

Whether linked to the quake or not, there is little dispute among scientists that animals can predict earthquakes, possibly through sensitivity to pressure waves.

"Physical and chemical stimuli emanate from the earth prior to an earthquake and animals probably sense that," said Dr George Pararas-Carayannis, a chemist and oceanographer who is president of the Honolulu-based Tsunami Society."

7. In China, prior to the May 2008 earthquake,Mianzhu residents feared the toads were a sign of an approaching natural disaster, but a local forestry bureau official said it was normal, the Huaxi Metropolitan newspaper reported May 10, two days before the earthquake.

The day of the earthquake, zebras were banging their heads against a door at the zoo in Wuhan, more than 600 miles east of the epicenter, according to the Wuhan Evening Paper.

Elephants swung their trunks wildly, almost hitting a staff member. The 20 lions and tigers, which normally would be asleep at midday, were walking around. Five minutes before the quake hit, dozens of peacocks started screeching.(http://www.livescience.com/mysteries/080516-llm-predict.html ).

8. Elephants, mole rats, birds, fish, tigers, rhinos, hippo, okapi, giraffe and many other animals use infrasounds (sounds below the hearing range of humans) for communication, detection of prey, or navigation. They do this and/or seismically (felt/heard through the earth), atmospherically, (through the air) and underwater in the case of whales and dolphin and fish.Earthquakes, tsunamis, and even hurricanes and cyclones generate very loud infrasound. which is why people described the tsunami as a "roar."
