MBARI’s advanced underwater technology reveals history of earthquakes in the Pacific Northwest

A new research publication, led by the USGS Pacific Coastal and Marine Science Center, used MBARI’s advanced technology to map the distribution of deposits left on the abyssal seafloor after an earthquake. These findings will help geologists reconstruct the seismic history along the Cascadia Subduction Zone, so coastal communities can assess the risk of future quakes.
