Beginning in early November 2008 Redoubt Volcano, 106 miles southwest of Anchorage, AK, began to show signs of unrest including significant changes in gas emission and heat output. On November 5, 2008, the Alaska Volcano Observatory (AVO) raised Redoubt's Aviation Color Code to Yellow and the Volcano Alert Level to Advisory. A significant increase in earthquake activity...

A drill rig at the Mount Elbert test site in Alaska's North Slope, just west of Prudhoe Bay. USGS joined BP Exploration (Alaska) and the U.S. Department of Energy to drill a test well to study natural gas production from gas hydrate deposits. Read more about the Mt. Elbert project...
The first priority of any eruption is to assess current status and what might happen next. To accomplish this, Mount St. Helens became one of most heavily monitored volcanoes. At the start of the 2004–08 eruption, 13 permanent seismic stations operated within about 12 miles of Mount St. Helens. By the end of the eruption, the seismic network consisted of 20 stations....
Throughout the eruption, scientists installed monitoring stations to track volcanic activity, deployed temporary monitoring ""spiders"", monitored the temperature of lava spines and created time-lapse of dome growth. During the 3+ years of the eruption, lava piled up to form a new dome 460 m (1,500 ft) high. The 92 million cubic meters (121 million cubic yards, or 36,800...
