Mount Etna, Europe's most active volcano, continues to spill rivers of lava following a July 17 eruption. The recent activity of the 3,315-meter (10,876-foot) high volcano can be seen in two images taken Sunday, July 29 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA's Terra spacecraft.
The images are available at:
One image shows the lava advancing toward the town of Nicolosi on the Italian island of Sicily. While the last two days have been relatively calm, a river of lava is about 4 kilometers (2.5 miles) away from the town. Thick ash clouds caused airport closures and forced residents in the nearby city of Catania to use umbrellas while walking outside. The other image shows a large sulfur dioxide plume coming from the summit of the volcano.
