Online_Linkage: https://doi.org/10.5066/P924775B Description: Abstract: This dataset includes grain-size data from sediment cores collected from lacustrine and fjord basins in southcentral Alaska following the 2018 Anchorage earthquake. The cores were collected with a percussion driven gravity corer for use in regional hazard assessments relating to Alaska’s seismic hazard. Purpose: Identification of fault-related submarine hazards is a primary mission of the USGS Coastal and Marine Hazards and Resources Program. Intraslab earthquakes, which occur at depth within the subducting plate, can cause intense shaking at the Earth’s surface, but do not cause surficial faulting or result in significant land level changes. The seismic shaking associated with intraslab earthquakes can remobilize subaqueous sediment and lead to gravity driven sediment flows, potentially creating a record of past shaking from these events. To gain a better understanding of the conditions that produce seismically triggered deposits in subaqueous basins the USGS collected Chirp seismic and sediment cores from several lakes and fjords following the M7.1 2018 Anchorage earthquake. 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.

Lineage: Process_Step: Process_Description: Cores were collected using a UWITEC percussion driven hammer core during U.S. Geological Survey cruises 2021-612-FA, 2020-615-FA, 2020-625-FA. The cores were transported back to the USGS Pacific Coastal and Marine Science Center core lab for subsequent analyses. Process_Date: 20210622 Process_Step: Process_Description: The grain-size distributions of samples were determined in the USGS Pacific Coastal and Marine Science Center sediment lab. Sediment intervals of interest were sampled at 2-3mm interval (sample size ~0.5-2 grams). 10mL of deionized (DI) water was added to sample along with 2mL of a 30 percent hydrogen peroxide solution to remove organic material. Sample was then heated at 250 degrees Celsius to remove any remaining hydrogen peroxide. Afterwards 100-200mL of DI water were added and allow to settle 7 or more hours. Following settling, the sample was decanted to 10mL, followed by the addition of 1mL of 2 percent hexametaphosphate (Calgon) and sonicate for 15 minutes. The particle-size distribution was analyzed using a Beckman Coulter LS 13 320.
