The more we know about fires, the more we can protect those we care about.
Learn about "Fiery" Disasters with Remote Sensing Technology

Satellite remotes sensing technology is one of the major data source for fire damage assessment. NASA’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) allows scientist to obtain the temperature pressure information of plants around the world, produce high accuracy heat-spot maps, and assist in planning emergency countermeasures against drought and mountain fires.

More than 60 wildfires were burning across at least 10 states in the western United States on July 13th this year, with the biggest one in Oregon.

Change in Bootleg Fire

ECOSTRESS captured the surface temperature data of the Bootleg fire in the state of Oregon between July 7 and 22nd. The detection device dynamically traced the movement change trend of the Bootleg fire. In these GIFs, red areas represent the fire fronts.  It also obtained surface temperature data of Dixie fire in northern California between July 15 and 24th, which has doubled in size to more than 220,000 acres in simple a few days.

Change in Dixie Fire

About one year ago, forest fires had started in Sichuan and Yunnan provinces, and Xinhua published a special report using satellite imagery to monitor the fires and their impact. On the same day, TerraQuanta quickly responded and accurately calculated the locations of the fire points and the fire fronts, providing Xinhua News Agency with an analytic chart of the fire area and the fire front in Muli County, Liangshan Prefecture, Sichuan Province.

Above is an picture showing the map with highlighted burnt area and fire fronts. Areas of approximately 6.5 square kilometers were damaged by the fire, and edges of fire reached 17 kilometers. These data were acquired by comparing the differences in normalized burn ratio between images before and after fire started.
