Italy’s Mt. Etna unleashed a spasm of volcanic activity on April 10, 2011. Ash, lava, and gas were all released from the episode which lasted through the course of the day.
Volcanic ash from earlier eruptions has settled onto the snowy landscape, leaving dark gray swaths. The ash stains are confined to the south of the Karymsky’s summit, one large stain fanning out toward the southwest, and another toward the east.
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.
