Giant earthquakes and tsunamis devastate western Oregon every 300 to 600 years. The last one hit in 1700, so we're due anytime. This informative, entertaining book tells the stories of Oregon's past floods, fires, and eruptions -- including the Vanport Flood, the eruption of Mt. St. Helens, and the Columbus Day Windstorm. Then it investigates the cycles behind our natural disasters and takes a look at what may happen when the next "Big One" strikes.
