Watch When Nature Strikes Back: Landslides

Mountains are created by gigantic forces beneath the Earth's surface. However, while they are still growing from below, their surface weathers away and they begin to disintegrate. Then comes the fateful day, however, on which the inner stability of a mound is disturbed, and gigantic masses of debris and mud careen downhill: These peaceful mounds then become deadly landslides.
