Powerful Santa Ana winds have fueled more than 10 large wildfires throughout Southern California, stretching from Santa Barbara to San Diego.

This pair of images, depicting the area around Los Angeles on October 21, 2007, shows just how quickly the fires grew.

The left image, captured by NASA’s Terra satellite at 11:35 a.m. local time, shows several fires giving off small plumes of smoke. Just over 3 hours later, at 2:50 p.m. when NASA’s Aqua satellite passed overhead, large amounts of smoke were pouring from blazes northwest of Los Angeles. Actively burning fires are outlined in red.

In the right image plumes of smoke can be seen blowing off the coast, indicating the intensity of the winds and the presence of additional fires farther south.
