After 10 days of relative calm, Alaska's Augustine Volcano erupted twice Friday, three times Saturday and once on both Sunday and Monday. Here, a view of the volcano on Jan. 24, 2006. The photo looks toward Augustine's south flank, located in south-central Alaska about 175 miles southwest of Anchorage. The volcano, 4,134 feet tall, poses a hazard to Anchorage and the trans-Pacific air traffic around it.
