This is a satellite image of Anchorage, Alaska. The red line shows the equivalent area that the 2009 Redoubt lava dome would cover - to a depth of 3 feet! The dome is about 70 million cubic meters. This volume was calculated by USGS geologist Angie Diefenbach at the Cascades Volcano Observatory, using oblique photos taken by AVO geoscientists.
