Brian Andrews (USGS) and Nathan Miller (USGS) during fieldwork on Skilak Lake, Alaska 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.
