Collecting More Than Just Seismic Data Along the Cascadia Fault
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.

New Study Helps to Explain ‘Silent Earthquakes’ Along New Zealand’s North Island
Underwater mountains may help to dampen movements along faults that otherwise have the potential to generate large earthquakes.

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

Seismic Data on Deck: Sounding for the Cascadia Megathrust Fault
Using sound and a 7.5-mile-long streamer towed behind the boat, scientists can collect a tremendous amount of data from under the seafloor.
