- Major incidents
Hover over an incident icon for the latest information from fire managers. Click on a layer in the menu to show or hide that layer. Not all fires will have perimeters mapped. Thermal satellite fire detections from the MODIS satellites each represent a thermal event somewhere in the 1 km square area defined by the icon. VIIRS visual and infrared fire detections represent an identified event somewhere within a 375 meter square centered on the icon. Both MODIS and VIIRS fire detections can be confused by smoke, cloud cover, dense forest canopy or meteorological conditions.
