Ash Plumes

NASA Moderate Resolution Imaging Spectroradiometer (MODIS) imagery are useful for identifying and tracking ash plumes from volcanic eruptions. The use of near real-time (NRT) satellite data for monitoring volcanic plumes is undergoing further developments to enable quantitative retrievals to be produced, which should enable a global capability for volcanic ash monitoring to be introduced.

On June 22, 2019, the Raikoke volcano on the Kuril Islands erupted. It produced an explosive eruption that sent ash billowing thousands of meters into the air. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image on the morning of June 22. At the time, the most concentrated ash was on the western edge of the plume, above Raikoke. Read more about the event at NASA's Earth Observatory.
