Mount. AVO monitors Aniakchak with a local network, which consists of six seismometers, a web camera, and a single infrasound sensor, as well as satellite remote sensing data and regional infrasound and lightning networks. But more than 50 years prior, Alaska was also home to the world's largest volcanic eruption of the 20th century. He said if activity increases, Adak could get ashfall from Great Sitkin, located on an island about 27 miles away.
