ANCHORAGE, Alaska—Diminished earthquake activity led authorities to reduce the warning levels at two volcanoes on an uninhabited island in Alaska’s Aleutian chain because of the decreased potential for eruptions.

The Alaska Volcano Observatory on Thursday lowered the warning level to “Advisory” status from “Watch” for both Tanaga and Takawangha volcanoes on remote Tanaga Island, located about 1,250 miles southwest of Anchorage.
