The Alaska Volcano Observatory posted a "watch" alert due to the increase in activity, which suggests "that the eruption at Shishaldin has intensified," AVO wrote. Elevated surfaces temperatures were shown on satellite images near the volcano's summit.
Shishaldin, elevation 9,373 feet, is located on Unimak Island on the Aleutians. The volcano has been listed as "orange" for months, coordinating scientist with the Alaska Volcano Observatory Jeff Freymueller said, as small explosions within Shishaldin's crater have been occurring "pretty much all the time." The color code "orange" indicates an ongoing level of heightened activity at a volcano.
These small explosions within the volcano are likely to continue for "some time," Freymeuller said, bringing along the "potential that at any moment ... you could have a much bigger (explosion)."
