Latest Juan de Fuca Plate Stories
Tall buildings, bridges and other long-period structures in Greater Vancouver may experience greater shaking from large (M 6.8 +) earthquakes than previously thought due to the amplification of surface waves passing through the Georgia basin
Every 15 months or so, an unfelt earthquake occurs in western Washington and travels northward to Canada's Vancouver Island.
An earthquake hotspot just 50 miles off the Pacific Northwest coast is on the verge of unleashing itself on Seattle, Portland and Vancouver, similar to the damage that shattered Chile.
For most of a decade, scientists have documented unfelt and slow-moving seismic events, called episodic tremor and slip, showing up in regular cycles under the Olympic Peninsula of Washington state and Vancouver Island in British Columbia.
In the last decade, scientists have recorded regular episodes of tectonic plates slowly, quietly slipping past each other in western Washington and British Columbia over periods of two weeks or more, releasing as much energy as a magnitude 6 earthquake.
A peculiar swarm of earthquakes have been occurring off of Oregonâ€™s central coast, resembling those that happen just prior to a volcanic eruption. However, scientists are baffled as there are no volcanoes in the area.
A swarm of undersea earthquakes off the Pacific Northwest coast has scientists from the University of Washington scrambling in hopes of glimpsing of two tectonic plates pulling apart.
The Pacific Ring of Fire, or Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 25,000 mile horseshoe shape, it’s associated with an almost continuous series of oceanic trenches, volcanic belts, volcanic arcs and/or plate movement. The Ring of Fire contains 452 volcanoes and is home to over 75 percent of the world’s active and dormant volcanoes. It’s sometimes called the circum-Pacific belt or the...
