The February 13, 2014, violent eruption of Kelud stratovolcano in Java, Indonesia sent volcanic ash covering an area of 70,000 square miles (181,300 square kilometers), and prompted the evacuation of tens of thousands of people. Earlier 20th century eruptions killed thousands of people, mainly as the result of hot mudflows ("lahars"). This image from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft was acquired on February 20, after the eruption had greatly diminished. Ash-covered areas are seen on the north slopes of the volcano (the summit is hidden underneath clouds); ash-choked rivers flow down the west and southwest flanks of the volcano. ASTER's thermal infrared channels show continued activity at the summit. The image covers an area of 14.2 by 16.1 miles (23 by 26 kilometers), and is located at 7.9 degrees south, 112.3 degrees east.
