Unveiling Earthquake History at Skilak Lake, Alaska

Peter Haeussler (USGS), Brian Andrews (USGS), Hannah Brewer (WHOI), and Tim Kane (WHOI) prepare to launch the OBS float rig at the Upper Skilak Campground Boat Ramp. R/V Lutris (background) was used to tow the rig to the deployment sites. This is part of a USGS effort, in collaboration with partners from the Woods Hole Oceanographic Institution Ocean Bottom Seismic Instrument Center, to create a record of past earthquakes from Skilak Lake on the Kenai Peninsula of Alaska. In May 2024, they deployed two seismographs on the bottom of the lake and eight seismographs on land around the lake. Each instrument will collect data there for about 1 year.
