Chirp seismic-reflection and navigation data collected in Alaskan lakes and fjords following the 2018 Anchorage earthquake

Chirp seismic-reflection data and associated navigation files were collected from lacustrine and fjord basins in southcentral Alaska following the 2018 Anchorage earthquake. These data were collected from a 25-foot Boston Whaler (R/V Moose Dancer),18-foot cataraft (R/V Enterprise), and the R/V Alaskan Gyre in the summers of 2020 and 2021 for use in regional hazard assessments relating to Alaska’s seismic hazards.
