MODVOLC uses infrared satellite data acquired by NASA’s MODIS instrument to monitor Earth’s surface for the thermal emission signature of volcanic eruptions, wildfires, and anthropogenic heat sources (e.g. gas flares). Two MODIS sensors, one on the Terra satellite, one on the Aqua satellite, allow the entire Earth to be monitored every 48 hours. If an eruption is detected, its details are reported here, usually within 12-18 hours of the satellite passing over the volcano. You can search, plot, and download the data using the tools below. If you are unsure as to what you are looking at, this page provides links to published papers and other information that describe the data, and this website. This project is funded by NASA grant NNX14AP37G.
