Images: To Catch an Erupting Volcano

When Augustine Island volcano off Alaska began erupting in December 2005, researchers rapidly mobilized to deploy instruments to monitor it. (Photo by T.A. Plucinski, Alaskan Volcano Observatory/U.S. Geological Survey)

Five ocean bottom seismometers (red dots) were deployed around the Augustine volcano in February 2005 and retrieved in April. The seismic recordings they collected should reveal what goes on inside and underneath an active volcano, improving understanding of the magmatic processes that precede and lead to eruptions.
