Input: Consider Input: There was a PBS program 'Nature', just aired a couple of weeks ago, about whether animals can predict nature disasters like earthquakes and tsunamis. Whether animals can predict earthquakes is not conclusive. But there's a scientist in Berkeley (forgot his name) claimed he had predicted earthquakes accurately in the last few decades. What he used was simply newspaper ads on missing pets. He said normally you'd see about 10-15 missing pets ads, but before earthquakes, the missing pets ads would increase. His theory is contraversial, but it's worth a try. You may want to test that theory.

The program also mentioned about the terrible tsunami in Asia over a year ago. It mentioned none of the animals got harmed since they 'knew' the waves were coming and escaped from the disaster.

One theory is that animals can hear low frequency sound from beneath the earth, like grinding sound of moving rocks.

Anyway, you'll find some interesting programs on PBS stations.
