Many animals do strange things before an earthquake. This news may be important. Earthquakes can kill people and knock down homes. The animals may help to save lives. Some animals make a lot of noise before an earthquake. Farmers have told about this. Dogs that are usually quiet have started to bark. Horses on farms have run around in circles. Mice have left their holes and run away. Cows have given less milk. In a town in Italy,cats raced down the street in a group. That happened only a few hours before an earthquake. In San Francisco,a man kept tiny pet frogs. One Sunday,the frogs jumped around more than ever. They made loud noise,like bigger frogs. That night,an earthquake struck the city. People want to know when an earthquake is coming. Then they can get away safely. Right now,there is no sure way to know that ahead of time. Maybe the best idea is watching the animals.
