Researchers prepare Portland International Airport for megaquake

Researchers help prepare Portland International Airport for when The Big One hits Researchers at Oregon State University just saved the Portland International Airport more than $30 million by blowing up the ground around it. Author: Keely Chalmers (KGW) Updated: 10:16 PM PDT July 8, 2021 The phenomenon is called liquefaction. It happens when sandy soil with shallow groundwater shakes in an earthquake and behaves like liquid. And it s a danger the Pacific Northwest could face in the coming years. The Portland International Airport (PDX) is in an area at high risk for liquefaction. We have to have a runway. And since both runways are highly susceptible to liquefaction, we re working towards that, said Tom Wharton, a project engineer with the Port of Portland.

Armin Stuedlein led the project, which involved three days of test detonations at the airport in 40- and 90-foot-deep blast casings. By studying the series of controlled blasts, researchers could determine how the sand and silt soils underlying the airport would respond to a “megathrust earthquake” and what ground improvements are needed to prevent liquefaction and keep the runway intact.
