Geophysical and core sample data collected in lakes and fjords of southcentral Alaska following the 2018 Anchorage earthquake (ver. 2.0, October 2023)

This dataset includes sub-bottom seismic and sediment core data collected during USGS field activities 2021-612-FA, 2020-625-FA, and 2020-615-FA. Sub-bottom data include Chirp seismic in SEG-Y format with associated navigation tracklines. Core data include photo and computed tomography (CT) scans, and various mineralogical, radiometric, and other sampling data. Users are advised to read the metadata documents thoroughly for information on each data type provided. These data were collected from several lakes and fjords following the M7.1 2018 Anchorage earthquake by the USGS to gain a better understanding of the conditions that produce seismically triggered deposits in subaqueous basins. These data are intended to further our understand of geologic hazard in southcentral Alaska, improve risk assessments for local communities and critical infrastructure, and to provide data for future research on regional paleoseismic records in southcentral Alaska.
