Satellite views show massive clouds of wildfire smoke shrouding vast areas of the Oregon and Washington states as vicious blazes destroy hundreds of square miles of forest.
The Cedar Creek wildfire in the Willamette National Forest, lit by lightning in early August, according to NPR (opens in new tab), is currently the largest of the nearly two dozen wildfires burning in the region.
Satellites watched as the Cedar Creek fire grew over the past weekend to 135 square miles (90 square kilometers). In an image captured by NASA's Terra satellite on Saturday (Sept. 10), smoke from the Cedar Creek Fire can be seen spreading along the Pacific coast and over the ocean. High levels of fire-related air pollution have been reported in the state's capital, Portland, reducing air quality to "very unhealthy" levels, according to a NASA statement (opens in new tab).
A smaller fire in the state of Washington, called the Bolt Creek Fire, is also generating thick plumes of smoke that are clearly visible from space. The fire, which ignited over the weekend in the western foothills of the Cascade Mountains, is polluting air in Seattle and its surroundings.
The Bolt Creek Fire spread across 12 square miles (32 square km) of land within a day, fanned by powerful winds of a low-pressure weather system approaching above the Pacific Ocean, NASA said in the statement.
The northwest is not the only region in the U.S. suffering from devastating wildfires. In what has been a summer of weather extremes all over the world — a sign of continuing climate change — the U.S. has experienced another above-average wildfire season, although not as devastating as the seasons of 2020 and 2021.
In particular, California, plagued by an ongoing drought and severe heat waves, has witnessed a string of vicious blazes this year that have combined to ravage nearly 520 square miles (1,370 square km) of land. The Mosquito Fire in the Sierra Nevada foothills is currently the largest of the Californian wildfires, having destroyed over 47 square miles (120 square km) of forest since igniting last week.
