With fascinating experiments, models, and demonstrations, this scientific survey provides a vivid exploration of natural phenomena. Ideal for budding earth scientists, this in-depth resource demonstrates how to build a seismograph to record a simulated earthquake, compare pressure waves and shear waves the two types of ground shocks with a Slinky, and replicate a tsunamis destructive effect on a coastline built in a bathtub. The chapters answer questions...

On November 7, 1882 an earthquake rocked parts of Colorado, Wyoming, Utah, and Kansas. An isoseismal map for the main event and the felt area of an aftershock on November 8th, along with historic wave path and focusing considerations, suggest the epicenter was probably in north-central Colorado, perhaps in the northern Front Range or possibly southern Laramie Mountains. Similarities with the 1984 Laramie Mountains earthquake support an interpretation...

They are ignored until the earth trembles and FBI agent Judy Maddox discovers that the technology for a man-made earthquake is available. At which point a race against time gets underway.
