Unalaska and its port of Dutch Harbor sit in the Aleutian Islands at the edge of the Pacific Ring of Fire — one of the most seismically and volcanically active regions on Earth. The city is the top US fishing port by volume and handles billions of dollars of seafood annually. Nearby Makushin Volcano is considered potentially active, and the Aleutian Subduction Zone generates regular earthquakes and tsunami threat.
