The Big One is Coming

We know it’s going to be a big one, and we know it could happen at any time.  $15 million dollars has been awarded for a new research center to study the earthquake that could wipe us out.   Both Portland State and Oregon State University are playing a key role in the new center called CRESCENT, which stands for Cascadia Research Science Center.   We talked to Assistant Geophysics Professor Pieter Share about the likelihood of a 9.0 hitting the Pacific Northwest in the near future.  You can hear that interview here:


Here is the full press release from OSU:

CORVALLIS, Ore. – Oregon State University researchers will play key roles in a new multi-institution earthquake research center dedicated to the study of the Pacific Northwest’s Cascadia Subduction Zone, which is capable of producing earthquakes comparable to the largest recorded globally.

The U.S. National Science Foundation has awarded $15 million over five years to the Cascadia Region Earthquake Science Center, or CRESCENT. The center includes researchers from 14 institutions across the U.S., including Oregon State and Portland State University, and will be led by Diego Melgar of the University of Oregon.

Initially, CRESCENT will focus on foundational science to better and more holistically understand the complex dynamics of the Cascadia Subduction Zone, which runs from northern California to British Columbia.

“Cascadia is a unique tectonic environment. We really don’t have the traditional, everyday seismic signals that give us information about the state of stress of the Earth beneath our feet, but we know that these very big earthquakes occur,” said Pieter-Ewald Share, a co-principal investigator for CRESCENT and an assistant professor of geophysics in OSU’s College of Earth, Ocean, and Atmospheric Sciences.

Large earthquakes have been typical in Cascadia’s geologic history, with the most recent occurring in January 1700. Yet relatively few earthquakes are felt by the region’s population. Previous research indicates the subduction zone produced earthquakes as big as magnitude 9.0. A future event will significantly impact communities across the Northwest.

“Part of our goal here is to collectively explore and quantify the various data and signals unique to Cascadia, take advantage of emerging cutting-edge laboratory, modeling and computational tools and provide a more holistic idea of the seismic hazard posed by the subduction zone,” Share said. “This new, coordinated effort to push the science forward will positively impact and increase our resilience and preparation for a future event.”

Researchers will map out a strategic plan for the CRESCENT at a kickoff meeting in late October. More than 140 scientists, partners and educators will gather at the University of Oregon to launch the effort and begin building the community.

Three major pillars comprise the center’s work over the next five years. Along with the foundational science, the center will prioritize workforce development, to grow and diversify the next generation of geoscientists, and community collaboration, to translate and communicate the center’s findings and recommendations for improving earthquake resiliency of communities, businesses and infrastructure of the Pacific Northwest.

“The main goal of the center is to bring together the large group of geoscientists working in Cascadia to march together to the beat of a singular drum,” said Melgar, an associate professor of earth sciences at the University of Oregon and the center’s principal investigator and director. “The center organizes us, focuses collaboration and identifies key priorities, rather than these institutions competing.”

CRESCENT also includes Oregon State’s Michael Olsen of the College of Engineering; Ben Leshchinsky of the colleges of Engineering and Forestry; and Andrew Meigs and Anne Trehu of the College of Earth, Ocean, and Atmospheric Sciences, who will all serve as senior personnel for the project.

Meigs, a professor of geology, will play a leading role in the workforce development pillar of CRESCENT, which will be tasked with engaging, energizing and training the next generation of diverse geoscientists who will take on Cascadia’s biggest science questions in the future.

“The workforce effort will create experiential learning opportunities across a spectrum from high school to university students,” Meigs said. “We aspire to build cohorts of students from underrepresented groups and provide opportunity to interact with CRESCENT scientists by engaging in earthquake science and gaining skills and experiences that are relevant to their careers and communities.”

Share has various roles in the foundational science pillar and he and Olsen, an expert in earthquake engineering and hazard mitigation, will serve on the committee for the community collaboration pillar.

CRESCENT builds on a foundation of more than three decades of past and ongoing earthquake research at Oregon State, including the Cascadia Lifelines Program, a research initiative to improve performance of critical infrastructure during a major earthquake. Another significant and ongoing effort, the Cascadia Coastlines and Peoples Hazards Research Hub, seeks to increase understanding of the chronic and acute natural hazards and climate changes that face coastal communities.

Additional institutions involved in the project include University of Washington, Central Washington University, Western Washington University, Cal Poly Humboldt, Purdue University, Smith College, Stanford University, University of North Carolina – Wilmington, University of California, San Diego, Viriginia Tech and the U.S. Geological Survey.

CRESCENT is one of two earthquake research centers to be funded through the National Science Foundation’s Centers for Innovation and Community Engagement in Solid Earth Geohazards program.

The Southern California Earthquake Center, which has operated for more than 30 years, also received funding. That center’s activities include coordinating the annual “Great ShakeOut” earthquake drill and establishing the California Earthquake Country Alliance, which is dedicated to improving earthquake and tsunami preparedness, mitigation and resiliency.
