Seafloor Instrument Locations
28 long-term ocean-bottom seismometer (OBS) instruments will be on the seafloor from August 24th, 2021 through October 24th, 2022. These broadband OBS instruments are designed to monitor earthquake seismicity along the Queen Charlotte fault system in the area of the 2013 M7.5 Craig earthquake.
We urge fishing communities (particularly trawlers and longliners) to avoid these instrument locations within a ~200 meter radius to avoid entanglement hazards.
Please check this page for downloadable files with the latest instrument locations and coordinate information.
