We think that the occurrence of the big earthquake has
three kinds of influences.
1.An influence from the universe
The water of the sea goes up and down by the lunar influence.
2.An influence due to the atmospheric pressure
The energy of the tornado is very big.
A difference in the atmospheric pressure has strong energy.
3.The distortion of the ground
When plate moves, distortion becomes big gradually.
The final grade of the distortion, just before the big
earthquake, A kind of electric energy occurs.
So, an animal starts an unusual action.
The thing which isn't usually seen,like earthquake cloudy
weather, red moon, and so on are seen in the nature.
This is equal to the earthquake sign.
A decision is difficult because another thing sometimes
makes the same.
