Three volcanoes are erupting across the Aleutian Range — Great Sitkin and Semisopochnoi in the Aleutian Islands and Pavlof Volcano on the Alaska Peninsula.
Two companies are looking at the geothermal energy potential of Mount Spurr, an active volcano across the Cook Inlet from Anchorage.
UAF and NASA scientists found slight increases in radiant heat around volcanoes years before they erupted.
Satellite and webcam footage revealed small deposits of ash near the summit, but the ash cloud stayed below 10,000 feet.
When Redoubt erupted in 1989, the Alaska Volcano Observatory was just one year old and relayed information by fax machine and floppy disk. Today AVO uses an array of sensors, receivers and satellites to monitor dozens of Alaska volcanoes, including Redoubt.
Multiple pieces of evidence led scientists to the conclusion that there might be a 12-mile-wide caldera — a large volcanic crater — or a number of calderas, hidden underwater beneath the group of islands.
In this newscast: Bogoslof volcano was a haven for endangered animals, but scientists are studying whether they’ll return to the eastern Aleutian island. Former NBA player Carlos Boozer is returning to Juneau to host his Carlos Boozer Basketball Camp. An Alaskan radio station is facing $66,000 in fines for a list of violations.
Bogoslof’s unpredictable eruptions have prevented scientists from setting foot on the island. But it hasn’t kept them from seeing whether animals have returned.
Hilcorp says the project would eliminate the need to store oil at the Drift River Terminal. That terminal has worried environmental groups for years because it sits at the bottom of Mount Redoubt, an active volcano.
Nearly every year since Kasatochi erupted, scientists have returned to study how ecosystems respond to cataclysmic destruction.
