When the Earth MovesOnline Periodical or Article
Earthquakes can be disastrous, but the earth moves in many other ways as well--landslides, rockslides, mudflows, avalanches--sometimes with terrible results. When the Earth Moves explains how the earth is ever in motion, from gradual, daily occurrences such as soil creep to great events, such as when the ancient city of Ubar disappeared in a sinkhole. Delicate balances of tectonic plates, of water and gravity, and of snow and sound are ever changing. Author Sandra Downs explains what may tip the scales to set earth in motion with examples from around the world. Book jacket.
