This full-color, dynamically illustrated volume helps readers better understand the causes of fractures and the magnitude and violence of the forces deep within the earth. It contains shocking scenes of cities convulsed by earthquakes and volcanoes, natural phenomena that, in mere seconds, unleash rivers of fire; destroy buildings, highways, bridges, and gas and water lines; and leave entire cities without electricity or phone service. Earthquakes near coastlands can cause tsunamis, waves that spread across the ocean with the speed of an airplane. A tsunami that reaches a coast can be more destructive than the earthquake itself. All of this fierce dynamism is brought into vivid focus here with stunning photographs, cutaway diagrams, and information-packed infographics.
