We realize many natural phenomenon have happened before an earthquake,
for example, earth current, geothermy, ground water, electrical wave,
spring, and charged aerosols. Of course, it's difficult for us to
feel concretely numerical change by our five senses. But we've already
heard many examples which natural phenomenon, animal, and plant happen
mysterious things.
1975, In China, there is a good example which was observed despite
minimum damage. They carried out the prediction of the earthquake,
and proved right by observation of the people.
The mechanism of macroscopic anomaly phenomena has happened is that
already mentioned, unforeseen of physical science natural atmosphere
can cause animals to act strangely and natural phenomenons and plants
occur under great stress.
