Latest Mount Redoubt Stories
Scientists often detect a series of small earthquakes just before a volcanic eruption and a new study published in the Journal of Volcanology and Geothermal Research has shown that these tremors can happen in such a rapid succession – that they create sound vibrations that rise in pitch until the volcano erupts.
The Alaska Volcano Observatory has reported that the remote Pavlof Volcano continues to erupt and is now spewing a 60-mile stream of lava, ash and steam 20,000 feet into the sky.
More than a week after Alaska’s Cleveland volcano began erupting, sending ash clouds 15,000 feet into the air, another Alaskan mountaintop began rearing its ugly head. The Pavlof volcano, which sits about 350 miles northeast of Cleveland, showed signs on Monday that it was on the verge of eruption.
The Cleveland Volcano, which sits at the western end of Chuginadak Island (part of the Aleutian Islands), erupted in at least three low-level explosions that were not severe enough to cause significant threats to air travel, but did force federal aviation authorities to divert some flights farther north of the volcano as a precaution.
Recognizing well-established patterns of pre-eruption unrest in monitoring data is vital in volcanic eruption forecasting. To develop better monitoring procedures, however, understanding volcanic eruptions that deviate from these patterns is crucial as well.
If the Cleveland Volcano had any neighbors, then it decided to wake them up on Tuesday when the volcano shot off a thin cloud of ash several miles into the sky.
The two-month long, low-level eruptions occurring at a volcano in Alaska's Aleutian Islands have volcanologists worried that there could be a larger eruption forthcoming.
Mount Cleveland is reported to be on watch status with an aviation color code of orange, according to the Alaska Volcano Observatory (AVO).
Study of volcano-ice interaction offers window into geologic past and clues about Earth's long-term climate cycles.
Alaskaâ€™s Mount Redoubt has gradually slowed down in activity since the last eruption three months ago.
