    Earthquake and Tsunami-related Facilities and Programs at Oregon State University

The National Science Foundation-funded facility has been featured on news shows and documentaries for its research on the effects of tsunamis.
    • In 2007, the National Science Foundation awarded $1.6 million to OSU to establish the EarthScope national office. EarthScope is a nationwide program to explore the North American continent and better understand the physical processes that cause earthquakes and volcanic eruptions.
    • OSU operates one of the select group of seismic stations in the U.S. managed by the Incorporated Research Institutions for Seismology, or IRIS. It was featured in a recent issue of Terra magazine:
    • A national sediment core repository, funded by the National Science Foundation and coordinated by OSU, has 14,000 meters of ocean sediment cores that offer clues to past earthquakes, tsunamis, and climate change triggers.
    • Scientists at OSU’s Hatfield Marine Science Center in Newport utilize U.S. Navy hydrophones from an array called SOSUS (Sound Surveillance System) to listen for undersea earthquakes – as well as landslides, moving ice sheets and marine mammal vocalizations.
    • In OSU's Wood Innovation Center, researchers design and test earthquake-resistant structures, from residential framing to commercial product displays.
    • Engineers in OSU's Structural Engineering Laboratory test the ability of bridges to withstand wave and storm impacts. They have evaluated the survivability of causeways that cross coastal waters in Florida and the likelihood that bridge foundations on the Oregon Coast would be subject to tsunamis.
