Plume from Rabaul Volcano

May 22, 2013
Rabaul Volcano emitted a plume of ash and steam on the afternoon of September 10, 2009. This minor eruption continues a period of intermittent activity at the volcano that began in August of 2006. According to the Joint Air Force & Army Weather Information Network, the plume extended up to 30 nautical miles northwest of Rabaul’s summit. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this true-color image of the event. Rabaul is a pyroclastic shield volcano. Composed from broken rocks and debris from earlier eruptions, it has a wide perimeter and low profile. Before a major 1994 eruption that forced a large-scale evacuation, Rabaul had served as a natural harbor for the city of the same name.
