Summary
Seismic-reflection data and cores were collected in Ozette Lake, Washington, from 2019 to 2021. These data were used to investigate submarine landslide deposits triggered by large Cascadia Subduction Zone earthquakes. Identification of fault-related submarine hazards is a primary mission of the USGS Coastal and Marine Geology Program. In the US Pacific Northwest region, the greatest earthquake and tsunami threat is posed by the Cascadia Subduction Zone. From 2019-2021 the USGS carried out a detailed field investigation of earthquake-triggered landslide deposits in Ozette Lake, WA, to reconstruct the timing and severity of large subduction zone earthquakes in northern Cascadia. Field data collected as part of this investigation include boomer single-channel seismic, chirp seismic, and sediment cores. These data are intended to further our understanding of geologic hazards relating to the Cascadia Subduction Zone, improve risk assessments for local communities and critical infrastructure, and to provide data for future research on regional tectonic and sedimentary history of northern Cascadia.
