Volcano erupts, fishing boat rescues 10 people

This image released by Alaska Volcano Observatory on Sunday July 13, 2008 shows the Okmok Caldera in Alaska as viewed from an Alaska Airlines jet in early June, 2007. The 3,500-foot Okmok Caldera, which consists of a 6-mile-wide circular crater about 1,600 feet deep, erupted with little warning Saturday morning July 12, 2008, just hours after seismologists at the Alaska Volcano Center began detecting a series of small tremors.
