Ideally,people would like to know when an earthquake is going to happen and how bad it will be.In both Japan and China,people have long believed that earthquakes can be forecast.In Japan,scientists have wired the Earth and sea to detect movements.The Chinese have traditionally watched animals and plants for warning signs of earthquakes.For example,the Chinese have noted that before an earthquake,hens behavior changesthey refuse to enter their cages at night.2Lead-inActivities2AssignmentGlobalReadingDetailedReadingQ:How can we predict an earthquake?They have also noticed that snakes come out of the ground to freeze to death and that dogs bark a lot,even normally quiet dogs.Before the Hanshin earthquake in Japan,there were reports of large schools of fish swimming near the surface of the water.Certain birds,like pigeons,also seemed to be especially noisy and were reported to be flying in unusual patterns before the earthquake.2Lead-inActivities2AssignmentGlobalReadingDetailedReadingPerhaps most interesting,and most easily measured,is a chemical change in ground water before a quake.Experimental data seem to indicate that the amount of radon(Rn)in the water under the surface of the Earth waxes before an earthquake.2Lead-inActivities2AssignmentGlobalReadingDetailedReadingA:1)Wire the earth and sea
