Volcano Watch [No. 38]

17 September-23 September 2008

New Activity/Unrest:

• Bagana, Bougainville
• Galeras, Colombia
• Piton de la Fournaise, Reunion Island

An ash plume ejected from Bagana (right), just south of the dark-colored caldera lake of Billy Mitchell, rises into the atmosphere.

Steam clouds rise from an andesitic lava flow descending the NW flank of Bagana on April 26, 1988. The massive symmetrical lava cone, one of the most active volcanoes in Papua New Guinea, was largely constructed by an accumulation of viscous andesitic lava flows. – Photo by Wally Johnson, 1988 (Australia Bureau of Mineral Resources).
