Mount Etna, Europe's most active volcano, continued its latest eruptive activity with a new lava flow from the recently formed southeast crater. In this February 7, 2014 image acquired from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft, vegetation is red, snow is white and bare lava flows are dark gray. The yellow pixels are areas that are highlighted in the thermal infrared channels, and indicate the hot crater (single spot) and the lava flow. To the east, the thin blue-gray cloud is ash and gas emitted from the crater. The image covers an area of 12.4 by 13.7 miles (20 by 22 kilometers), and is centered near 37.5 degrees north, 15 degrees east.
