Hundreds Of Washington Schools Start Academic Year With Failing Grade On Quake Safety

By Tom Banse September 8, 2021

The Qushan Primary School ruins, where a total of 407 teachers and students were killed when a 7.9 magnitude earthquake hit China’s Sichuan province in 2008.

Tens of thousands of public school students in Washington state returned to classes this month in school buildings judged to be at risk of collapse in a strong earthquake. A new report to the state Legislature prepared by state geologists and a structural engineering firm gave the lowest possible seismic safety rating to more than 90 percent of the school buildings Read More

Seismic Research Ship Goes Boom-Boom To Seek Answers At Origin Of The Next Big One

By Tom Banse July 14, 2021

The vessel Marcus Langseth in Washington state.

Earthquake researchers are eager to dig into a trove of new data about the offshore Cascadia fault zone. When Cascadia ruptures, it can trigger a megaquake known as "the Big One." The valuable new imaging of the geology off the Oregon, Washington and British Columbia coasts comes from a specialized research vessel.Read More

By Tom Banse February 26, 2021

Smartphone users who opted in to a test of the West Coast earthquake early warning system got an early taste on Thursday of what is to come. Mobile phones from Seattle to Olympia blared with an alarm for imaginary incoming shaking. The earthquake warning system -- already operational in California -- will launch for the general public in Oregon on March 11 and statewide in Read More

Unlike the Cascadia Subduction Zone, the faults in eastern Washington are in the upper crust, (the outermost layer of the earth). That means they’re closer to the surface and to communities. They may not produce as large of an earthquake as the subduction zone off the coast, but the earthquakes these inland faults can produce could significantly damage infrastructure in Read More

The Big One — And Another One. Research Shows Cascadia Quakes Sometimes Trigger San Andreas

Scientists found nine to eleven instances over roughly the last 3,000 years where a Cascadia earthquake seems to have triggered a San Andreas quake. The vast majority of great Cascadia quakes during that period have a correlation on the San Andreas Fault. Read More

If you live at the foot of a dam – or downriver – you may wonder what could happen if an earthquake rumbled nearby. Dam managers say it’s something they’re constantly watching, but major shaking east of the Cascades shouldn’t cause too much damage. Read More

Emergency Managers Stress Need For Earthquake Preparation East Of Cascades

By Cameron Sheppard October 15, 2019

Road damage due to liquefaction from the 2001 Nisqually Earthquake in Thurston County, Washington. Liquefaction is when the soil turns to jello during intense shaking.

Emergency managers say a lot of the burden for eastern Washington and Inland Northwest communities will come from having to help house and provide services for people who will be displaced from western Washington following the aftermath of a potential large-scale earthquake. Read More

People visiting or living along the Pacific Northwest coast may be completely cut off after "The Big One" —the feared magnitude 9.0 Cascadia earthquake and tsunami. For that reason, the U.S. Navy has been scouting landing sites along the coast for disaster relief delivery by sea. The quake preparations ticked up a notch on Monday, with a practice delivery of supplies using Read More

Last September, a magnitude 7.5 earthquake followed by a tsunami devastated a region of Indonesia, killing more than 4,300 people. Two Oregon State and University of Washington professors who surveyed the aftermath say the far-away disaster should elevate attention to quake-induced landslide risks here at home in the Pacific Northwest.Read More

One way to predict the risk of earthquakes in the Pacific Northwest is to look at how often they occurred in the past – and, for several groups of geologists, delving into the fault lines themselves. The evidence lies in trenches the scientists cut across fault lines in northwest Oregon and on the north Olympic Peninsula.Read More

Portland Closer To Mandating Earthquake Retrofits For Older Buildings

By Deborah Wang June 14, 2018

After years of debate, the Portland City Council has taken a big step toward making the city’s old brick buildings more earthquake-safe. The Council voted unanimously June 13 for a resolution that would require owners of unreinforced masonry buildings to retrofit their properties. Those buildings, nicknamed URM's, are at high risk of collapse in an earthquake.Read More
