NASA satellite data shows smoke from dozens of large wildfires in Oregon, which have burned over one million acres following a series of dry thunderstorms.
Key facts
- •Dry thunderstorms on July 15, 2026, triggered thousands of lightning strikes across Oregon and Washington.
- •Over 10,000 firefighters are engaged in suppression efforts across the state.
- •Oregon wildfires have burned more than one million acres as of July 27, 2026.
- •National wildfire acreage has reached 4 million acres, surpassing the 10-year average of 3.4 million.
- •State officials issued air quality advisories for eastern Oregon due to smoke from the fires.
NASA’s Aqua satellite captured images on July 26, 2026, showing smoke blanketing Oregon as dozens of large wildfires burned across the state. The fires were ignited by thousands of lightning strikes from dry thunderstorms that moved across the Cascade Range on July 15. These blazes have since been fueled by gusty winds, extreme drought, and summer heat, leading to widespread air quality advisories and evacuation orders.
By the numbers
Fire Activity and Containment Efforts
More than 10,000 firefighters are currently working to contain the blazes. As of July 26, major active fires included the Hay Creek Complex, Brewer, Big Grass, Akawa Butte, and Powder River fires, with several reporting less than 5 percent containment. State officials have invoked the Emergency Conflagration Act to protect communities near threatening fires such as the Shingle, Bench, Beachcomb, and Second Flat blazes.
National and Regional Impact
According to reports, fires in Oregon had consumed more than one million acres by July 27, 2026. On a national level, the National Interagency Fire Center reported that wildfires have burned more than 4 million acres across the United States so far this season. This figure exceeds the 10-year average of 3.4 million acres recorded between 2016 and 2025.
Monitoring and Data Tools
NASA utilizes a global system of observations to track fire behavior and analyze trends. The agency provides several real-time monitoring tools to the public, including the Fire Information for Resource Management System (FIRMS), the Worldview browser, and the Fire Event Explorer, which help track the progression of wildland fires.
