This visualization shows the spread of the Caldor fire between August 15 and October 6, 2021, and the Dixie fire between July 14 and October 22, 2021, updated every 12 hours from a new fire detection and tracking approach based on near-real time active fire detections from the VIIRS sensor on the Suomi-NPP satellite. The yellow outlines track the position of the active fire lines for the last 60 hours, with the latest location of the fire front in the brightest shade of yellow. The red points show the location of active fire detections, while the grey region shows the estimated total area burned. The graph shows the cumulative burned area in square kilometers.
