The geologic history of the Pacific Northwest is as unique as the region itself. Created via tectonic plate movements and accretionary events, the original terranes were subsequently covered by sedimentary layers, ash, lavas, and glacial debris. These processes, begun millions of years ago, continue to affect the area, as seen in the eruption of Mount St. Helens and catastrophic Japanese tsunamis created by earthquakes in the Pacific Northwest. Understanding of the regions geology has led to new insight in volcanic eruption prediction, disaster preparedness, the environmental effects of mining, and urban development as it relates to geologic hazards. The Orrs detailed and informative writing style appeals to those with geologic training as well as beginners with an interest in the region. Each chapter covers a specific subregion, allowing for maximum flexibility both in the classroom and for the casual reader. The authors central theme that continental plate tectonics are the fundamental processes of Northwest geologic history permeates throughout the book.

Excerpt: The Puget Sound faults under the heavily populated Puget Sound region (Puget Lowland) of Washington state form a regional complex of interrelated seismogenic (earthquake-causing) geologic faults. These include (from north to south, see map) the: The Puget Sound region (Puget Lowland) of western Washington contains the bulk of the population and economic assets of the state, and carries seven percent of the international trade of the United States. All this is at risk of earthquakes from three sources: Concentration of mid-crustal (10-20 km deep) seismicity in the Puget Lowland. (Fig. 48 from USGS OFR 99-311)While the great subduction events are large and release much energy (around magnitude 9), that energy is spread over a large area, and largely centered near the coast. The energy of the somewhat smaller Benioff earthquakes is likewise diluted over a relatively large area. The largest intra-crustal earthquakes have about the same total energy (which is about one-hundredth of a subduction event), but in being closer to the surface will have more powerful shaking, and therefore more damage. One study of seismic vulnerability of bridges in t...

This collection of essays on the geology of the Pacific Northwest is written by geologist Steve Reidel. Reidel is an expert on Columbia River Basalt, the primary rock of the Columbia Basin, the semi-arid region of Washington State where most of the essays are set. The book collects a series of highly readable and witty essays Reidel has been writing for more than a decade for the Tri-City Herald, the daily newspaper of the Tri-Cities (Richland, Pasco, and Kennewick), Washington. Written in plain language, Reidel makes geology, an often difficult field to understand, accessible for all readers. The book is divided into four parts. The Making and Shaping of the Columbia Basin, part one, covers the creation of the Basin from the massive flows of lava covering 100,000 square miles-the largest on Earth-to the walls of water 600 feet deep created by Ice-Age floods that sculpted the region. Landmarks, part two, describes the creation and stories behind Tri-Cities landmarks such as Rattlesnake Mountain and the Two Sisters. The essays included in part three, Geohazards, focus on Cascade Mountain volcanoes, such as Mount St. Helens; area earthquakes; and regional tsunamis. Part four takes readers from the Tri-Cities to explore geologic wonders scattered around the region such as the Gorge at George Washington, Gingko Petrified Forest, and Beacon Rock State Park.
