March 24, 2009--Volcanic ash clouds a Webcam's lens as smoke and ash from a relatively subdued Redoubt Volcano lightly smudge the sky about a hundred miles (160 kilometers) northwest of Anchorage, Alaska, at sunset on Monday, March 23.

The Webcam feed was initially downed by the ash but "spontaneously" restarted Monday afternoon, according to the Alaska Volcano Observatory.

Between Sunday and Monday night, the 10,200-foot (3,100-meter) Redoubt Volcano (also known as Mount Redoubt) erupted six times, sending a volcanic ash cloud 9.5 miles (15 kilometers) into the sky, dusting nearby towns, sparking a swarm of earthquakes, and spurring massive mudflows.

Based on seismic data, a lava dome appears to be forming in the volcano's crater, volcanologist Peter Cevelli of the Alaska Volcano Observatory said March 24.

Early data suggest the volcano could continue erupting for days or even months. "I doubt this eruption is over," Cervelli said. "In fact, it may be just beginning."
