Ash Emission from San Cristóbal

July 17, 2013
In the waning days of 2012, a series of explosions and ash emissions occurred at Nicaragua’s San Cristóbal volcano. Small eruptions are relatively common at San Cristóbal, which has been restless since 1971. This natural-color image was captured on December 27, 2012, by the Moderate Resolution Imaging Spectroradiometer on NASA’s Aqua satellite. At the time, the Washington Volcanic Ash Advisory Center reported that the ash plume reached an altitude of 14,000 feet (4,300 meters), about 8,300 feet (2,500 meters) above San Cristóbal’s summit.
