Wildfires swept across parts of South Korea in March 2025. These images were acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the joint NASA/NOAA NOAA-21 platform on March 26, 2025. Zoom into central-eastern South Korea, where a large fire is visible near Andong, Uiseong County. The image on the left "A" side shows a true-color corrected reflectance image overlaid with fires and thermal anomalies detections, shown as red dots. The true-color image shows a large amount of smoke emanating from the fires. The right "B" side is a false-color corrected reflectance image which shows burned area in red and vegetation in green.
