The Iliamna volcano, located near the Cook Inlet in southern Alaska, last erupted in 1867, but would still rumble every few years due to avalanches large enough to register on nearby seismic and ...

(NewsNation) — A volcano in Alaska that last erupted in 1867 is displaying signs of rumbling. Located roughly 140 miles southwest of Anchorage, Iliamna has been dormant for over a century.

On Alaska's Kenai Peninsula, a flurry of small earthquakes shook the Iliamna volcano June 15. No surface activity was observed, however, and on July 1 the volcano was set at a normal alert code.

When a volcano is dormant, it typically doesn't tend to make much noise. However, the Iliamna Volcano in Alaska is defying what we thought we knew about volcanos by rumbling despite being marked ...

Over the past 12 months, an Alaskan volcano named Mount Spurr has become noticeably agitated: It’s been swelling, quaking, and venting noxious gases. As it stands today, the evidence could point ...

Alaska volcano researchers say seismic activity around Mount Spurr has continued to decline over the last month, but the closest active volcano to the state’s population centers could still erupt.
