More than a dozen wildfires ignited on Sunday in Northern California, a region at its driest this time of year.
Flames have consumed more than 170,000 acres of land, killed at least 23 people, destroyed thousands of homes, and forced tens of thousands of people to evacuate. Napa and Sonoma counties — the heart of California wine country — are especially hard-hit.
On Wednesday night, DigitalGlobe — a satellite imaging company that captures 100 terabytes’ worth of new photos of Earth each day.
“Although there is a lot of smoke in the area, shortwave infrared (SWIR) can penetrate the smoke and detect heat beneath,” DigitalGlobe wrote on its website.
The company took the following images on October 10 and 11 with its WorldView-3 and GeoEye-1 satellites.
“Some of these are natural colour, while others are shown in the Very Near Infrared (VNIR), where burned areas appear grey and black and healthy vegetation is red,” DigitalGlobe told Business Insider in an emailed statement.

This image, taken by WorldView-3 on Tuesday, shows the Santa Rosa area of Northern California burning.
Grey areas are burned, and red areas are vegetation. The bright line snaking through the hills of the area is the fire line burning through new material.
This zoomed-out view shows northwest Santa Rosa and Coffey Park -- parts of which were decimated by the flames.
The grassy lawn of a central park avoided the inferno that tore through this residential neighbourhood.
These vineyards' structures were torched to the ground, though the grape vines appear relatively undamaged (again, red shows healthy plants).
Neighbourhoods clustered around the Fountaingrove Golf and Athletic Club -- located just a few miles from Coffey Park -- were also destroyed.
