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.

Officials have yet to determine the origin of the Santa Rosa wildfires. However, dry and powerful "Diablo winds" that blow in overnight may have stoked and spread the infernos.

Satellites in space are recording shocking views of the disaster, an event that some experts are calling one of the worst firestorms in the state’s history.

On Wednesday night, DigitalGlobe — a satellite imaging company that captures 100 terabytes’ worth of new photos of Earth each day — released some of the first close-up views of the disaster from orbit.

"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 color, while others are shown in the Very Near Infrared (VNIR), where burned areas appear gray and black and healthy vegetation is red," DigitalGlobe told Business Insider in an emailed statement.

These images were taken in infrared, which can travel from the ground, pierce the veil of thick smoke, and be detected by the satellite’s SWIR sensor.

Gray 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.
