On January 22 2014 , the NASA satellite Terra captured an image of the volcano on Mount Edna in Italy diffusing a plume of gas and ash. An eruption is expected in the next couple of days.
The false color image made by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on Terra combines near infrared, red and green light. Snow in this image is white, lava (up to 100 years old) appears black and dark brown and vegetation is red. Volcanic plume is light grey.
