Vivid descriptions of recent disasters — including the great tsunami that swept down the Northwest coast inthe Oregon earthquakes, and the Nisqually earthquake.

The March Scotts Mills earthquake (M) and the September Klamath Falls earthquakes (M and M) demonstrated the potential hazards of crustal earthquakes in Oregon. Because of Oregon’s short history in dealing with seismic hazards, many fundamental issues, such as crustal fault activity and ground motion attenuation from.

Washington State Earthquake History Major earthquakes in Washington since (source: USGS) On Decema strong earthquake in the Cascade Mountains caused damage at Victoria, British Columbia, and Seattle.

Earthquakes from three different sources threaten communities in Oregon and the Pacific Northwest. These sources are crustal, subduction zone, intraplate, and volcanic earthquakes.

The most common are crustal earthquakes, which typically occur along faults, or breaks in the earth's crust, at shallow depths of miles ( km) below the surface. More about British Columbia earthquake history (NRC) Oregon and Washington.

Nea earthquakes of magnitude 1 to 6 have been recorded in Oregon and Washington since About 15 to 20 quakes a year are felt in the Northwest. Most small and moderate sized earthquakes in Oregon and Washington occur in the highly-populated Puget Sound region.

The Last Cascadia Subduction Zone Earthquake The Cascadia Subduction Zone has a history of producing very powerful earthquakes. The last known earthquake occurred on Januat around pm. The date is accurately known because the tsunami it generated was recorded by coastal residents in Japan. The Cascadia subduction zone along the Washington and Oregon coast is one of the biggest hazards to our state and is a good examples of this kind of fault.

Normal faults A normal fault occurs when two blocks are pulled away from each other. The most recent earthquake to significantly affect our region was the MaScotts Mills earthquake, a magnitude earthquake with an epicenter about 30 miles southeast of Washington County.

Impacts from this earthquake included toppled chimneys, damages to the state capitol, school closures, and the failure of walls made. An essential guide for anyone interested in understanding earthquake science or in preparing for the next earthquake, this book is also a call to action.

About the Book. In this expanded new edition of Living with Earthquakes, Robert Yeats, a leading authority on earthquakes in California and the Pacific Northwest, describes the threat posed by the Cascadia Subduction Zone, a great earthquake fault which runs for hundreds of miles offshore from British Columbia to northern research reveals subtle movements on the deepest part of.
