Scientists investigate rumbling at long-dormant Alaskan volcano that could signal avalanche rather than eruption near populated areas.

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 ...

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 ...

The Iliamna Volcano in Alaska is more than 10,000 feet (3,053 meters) above Cook Inlet, and recently, it has been active. The volcano felt tremors from the signature of avalanches big enough to ...

Its peak is covered in glaciers, snow and ice and it sits on a base of Jurassic-era granite, according to the NPS. Since its last eruption, the volcano was recorded ejecting smoke and light ash in ...

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.

R.G. McGimsey, /, Alaska Volcano Observatory “We’re not out of the woods yet, by any means,” Matt Haney, a researcher with the Alaska Volcano Observatory, told Alaska Public Media.

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.

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.

Right now, Spurr is by far more of an issue than Veniaminof for volcanologists. The volcano, located about 75 miles west of Anchorage, is currently in “code yellow” status.
