Before and after Landsat-8 images of California's Rim Fire. (Images: U.S. Geological Survey) California's Rim Fire may be 70 percent contained as of today, but this beast of a blaze is predicted to elude full containment until the end of the month, according to the latest report from Inciweb. When all is said and done, the fire is almost inevitably going to be at least the third largest wildfire in California history. At 235,841 acres right now it's already fourth on the list. And once it grows by a bit less than 5,000 acres, it will move into third place. With this in mind, I thought it would be a good time to compare before and after satellite images of the region. For this post, I chose Landsat-8 images. The first one in the animated gif above was acquired on April 25th of this year, and the second just this past Saturday, Aug. 31st. The reddish scar in the second image shows what has already burned. And I've marked one edge of the fire zone where active burning was still occurring as of Aug. 31. (If you look closely you can see bright orange spots indicative of fire there.) As you're looking at the burn scar, you might consider a geographic comparison to help you get a handle on its size: It is now more than one and a half times the size of the City of Chicago. Upwards of 4,500 people have been working to make sure the blaze doesn't get much larger than that, including brave air crews of the California National Guard, who have been dropping fire retardant from slow-moving aircraft at low level. That will be the subject of my next post. So make sure to look for that.
