Earthquakes, Volcanoes, and Tsunamis

Book excerpt: Earthquakes, volcanoes, and tsunamis don't happen every day, so how can budding scientists study how they work? Through experiments, models, and demonstrations. This in-depth resource will teach readers how to build a seismograph to record a simulated earthquake, compare pressure waves and shear waves—the two types of ground shocks—using a Slinky, and replicate a tsunami's destructive effect on a &“coastline&” built in a bathtub. Authors Matthys Levy and Mario Salvadori even discuss issues of modern architecture and civil engineering: how science can be used to protect buildings and property in earthquake-prone areas. Earthquakes, Volcanoes, and Tsunamis answers a wide array of questions about these phenomena. Can animals &“predict&” earthquakes? How have various cultures explained the movement of the earth throughout history? What is the Richter scale, and what does it tell us about the strength of a quake? And most important, readers will learn how to earthquake-proof their homes, and how to protect themselves should they experience a tremor.
