Asama Volcano on the Japanese island of Honshu showed signs of unrest, including ash plumes and increased seismic activity, starting in late January 2009.
In contrast to the explosive eruptions of the previous week, ash emissions from Mount Redoubt became more frequent but confined to lower altitudes on March 30, 2009. The commercial satellite GeoEye-1 captured a high-resolution view of the volcano the same day.
