Summary(Plain Language Summary, not published)
Under a joint Natural Resources Canada/US Geological Survey (USGS) program, a marine survey to investigate the central and northern parts of the Queen Charlotte-Fairweather transform fault system occurred in September 2017. The objective was to determine fault geometry, map submarine landslides and assess tsunami risk to the communities of northern BC and SE Alaska. Associated with the fault are large mud volcanoes that have plume columns extending as much as 700 m above the seafloor. Data from this survey will help define how fluids affect fault movement and earthquake recurrence. This report presents a summary of the survey with preliminary results and provides a detailed list of all data collected for subsequent analyses.
