Researchers are using ocean-bottom and land-based seismometers to record the R/V Marcus Langseth’s soundings from afar, to better understand the potential impacts of large earthquakes in the Cascadia region.

While researchers search for a megathrust fault off the Pacific Northwest coast, they are also helping to map the seafloor in high resolution and detect underwater methane seeps.

When using sound to search for an undersea fault, researchers must take special precautions to protect dolphins, whales and other vulnerable species.

Before embarking on a 6-week voyage to scan for Cascadia’s megathrust fault, the research team had to quarantine for two weeks in a hotel.

Climate change may be loading the dice for a tough summer.

Understanding how people will respond to climate dangers depends not only on top-down data, but also on bottom-up community engagement.
