Georgia Basin May Amplify Ground Shaking From Next Quake In Vancouver
2014-01-21 08:15:38

Seismological Society of America 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, according to two studies published by the Bulletin of the Seismological Society of America (BSSA). The basin will have the greatest impact on ground motion passing over it from earthquakes generated south and southwest...

Every 15 months or so, an unfelt earthquake occurs in western Washington and travels northward to Canada's Vancouver Island. The episode typically releases as much energy as a magnitude 6.5 earthquake, but it does so gradually over a month. New technology is letting University of Washington researchers get a much better picture of how these episodic tremor events relate to potentially catastrophic earthquakes, perhaps as powerful as magnitude 9, that occur every 300 to 500 years in the...

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, according to a recent Associated Press report. The fault has been in the dormant state for over 300 years, but the consequences could be devastating when it awakens. Recent computer simulations have shown a hypothetical magnitude 9 quake could shake the area between 2 to 5 minutes.  This would be strong...

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. They last three weeks on average and release as much energy as a magnitude 6.5 earthquake. Now scientists have discovered more small events, lasting one to 70 hours, which occur in somewhat regular patterns during the 15-month intervals between episodic...

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. The slip events coincide with regular occurrences of what scientists call nonvolcanic tremor, which showed up clearly on seismometers but for which the origins were uncertain. Now researchers from Italy and the University of Washington have...

A peculiar swarm of earthquakes have been occurring off of Oregon'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.  There have been more than 600 quakes during the past 10 days in an area 150 miles southwest of Newport. The largest quake was a magnitude of 5.4, with two others measuring greater than magnitude 5.0, OSU reported.Few of the quakes have been strong enough to be felt on...

SEATTLE (AP) -- 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 209-foot RV Thomas G. Thompson, a research ship from the university, headed for the Endeavor Hot Vents over the weekend after seismic equipment had detected nearly 3,800 small quakes as of late Thursday. Among those on the ship are scientists from Oregon State University and the National...

Pacific Ring of Fire
2013-02-19 13:18:27

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...
