Field Activity 2021-612-FA

Identifier 2021-612-FA
Alternate names 2018 Anchorage Quake Supplemental- Lakes Phase II
Purpose High resolution geophysical surveys and coring in lakes to detect geological evidence for the 2018 M7.1 Anchorage earthquake.
Location Kenai Peninsula Lakes (Skilak, Kenai, Tustamena) and Chelatna Lake
Summary Collected 45 hammer gravity cores from Skilak, Kenai, Tustumena, and Chelatna lakes. Field tested new PCMSC's new 216 Chirp on Skilak, Kenai and Chelatna lakes. In total collected over 50 NM of seismic profiles.
Info derived Stratigraphic framework, MTD detection, age dating, and grain size.
Comments Drake Singleton will be the point of contract for this operation.

Coordinates of percussion driven gravity cores collected in Alaskan lakes and fjords following the 2018 Anchorage earthquake navigation equipment This dataset includes coordinate information for 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. Drake Singleton
Chirp seismic-reflection and navigation data 0.5-16 kHz receiver Chirp seismic-reflection data and associated navigation files were collected from lacustrine and fjord basins in southcentral Alaska following the 2018 Anchorage earthquake Drake Singleton
Chirp seismic-reflection and navigation data collected in Alaskan lakes and fjords following the 2018 Anchorage earthquake 0.5-16 kHz receiver 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.
