According to the California Department of Forestry and Fire Protection, about 22 wildfires burning in multiple California counties have scorched over 170,000 acres of land, damaged or destroyed at least 3,500 structures and forced nearly 20,000 residents to evacuate.

In Northern California the wildfires are mostly concentrated in Napa and Sonoma counties since starting on Sunday, October 8th. Over 2,000 homes and commercial buildings, including wineries and resorts, are destroyed and at least 17 people died as a result of the fires. Hundreds of homes and businesses were destroyed in Santa Rosa, the largest city in Sonoma County.

In Southern California, a rapidly spreading wildfire has burned more than 8,000 acres in Orange County, through the hills of Anaheim, Orange and Tustin. At least 24 homes have burned, about 3,000 residents have been evacuated in and around Anaheim, and thousands of structures were threatened by the blaze.

As multiple sources report California wildfire information, Inhance is providing a composite wildfire burn area file derived primarily from satellite imagery and validated using online news reports. The data is in the form of 375-meter fire detection polygons and is useful to identify areas of fire damage but may not be suitable for pin-pointing burnt structures.
