Ash Emission from San Cristóbal
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
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.
