What causes a hurricane to form? Can animals sense an impending earthquake? Explore the dangerous and destructive side of nature - the awesome powers of tsunamis, hurricanes, tornadoes, wildfire, volcanoes and more in the updated edition of Natural Disasters. Each revised Eyewitness book retains the stunning artwork and photography from the groundbreaking original series, but the text has been reduced and reworked to speak more clearly to younger readers. Still on every colorful page: Vibrant annotated photographs and the integrated text-and-pictures approach that makes Eyewitness a perennial favorite of parents, teachers, and school-age kids.
