Satellite photo shows ‘burn scar’ from Arizona’s Bighorn Fire

NASA has released a stunning new image taken from space that shows the devastating impact of the Bighorn Fire that swept across Arizona in early June.

Taken by NASA’s Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), the image shows a 20 miles by 30 miles stretch of the Santa Catalina Mountains just north of Tuscon, where the wildfire began.

The image has been processed to highlight what NASA calls the ‘burn scar’ on the land, shown in black and dark grey, while areas with unburnt vegetation shaded in red.

The Bighorn Fire originally began on June 5, after a lighting strike ignited the surrounding area.

The fire spread rapidly, covering more than 114,000 acres or 48 square miles in just a few days, requiring more than 800 firefighters and emergency workers to fight it.

The fire was especially difficult to manage because of  plentiful dry vegetation for fuel while the mountainous landscape created air pressure differences that sped up the flame-laden winds.

‘It’s kind of like a chimney, the way the wind goes up the canyons,’ Dee Hines, a spokesman for the team fighting the fire, said.

‘Between the terrain and the wind, it’s been a really challenging fire,’

As of July 1st, the Bighorn Fire was still only 54% contained while between 130 and 150 homes in the area had been evacuated.

The Bighorn Fire was just one of three major wildfires in Arizona in June, with the Mangum Fire breaking out near the Grand Canyon National Park, and the Bush Fire sweeping over more than 180 square miles outside of Phoenix.

As of July 1st, the Mangum Fire was 67% contained, while the Bush Fire was 98% contained, leaving the Bighorn Fire as the biggest ongoing concern.

The ASTER satellite was originally launched in 1999 as a joint project with Japan’s Ministry of Economy, Trade and Industry to monitor large scale changes in Earth’s landscapes.

It uses a high spectral resolution imaging system that can take pictures of both visible light spectrum and infrared wavelengths, according to a post on NASA’s Jet Propulsion Laboratory news blog.

Images from the satellite have previously been used to help scientists study a range of subjects, including cloud formation, glacier advances and retreats, crop health, air pollution, and coral reef health, among many others.
