Today is relateed to earthquake warning.we did some practice in the class and ten left the class stayed out side.I remember something about animals.Some kinds of animals have stronger sesitivity than human being.for example horse responds few second before it occures.Because horse is able to percept the frequency of earthquake better than human being.according to this capability scientist are searching and creating some sensors for more accurate prediction about earthquake.animals are more susceptible to subtle environmental changes than humans are.
