Multichannel seismic reflection data were collected by the U.S. Geological Survey in May of 2015 outside of Palma Bay, Alaska. Seismic data were acquired coincidentally with high resolution bathymetry (Dartnell and others, 2022). Data were acquired to map the offshore extension of the Queen Charlotte-Fairweather Fault. The fault has produced several significant earthquakes during the last 150 years, yet little to no information exists along most of its length due to its location offshore. We aim to image the fault structure, mode of deformation and constrain its late Holocene slip rate for the northernmost segment. ...
