These Landsat images show Mount St. Helens after it erupted in May, 1980. The photo to the left is from 1984 and the photo to the right is from 2013. Scientists with the U.S. Forest Service have been studying photos like these for 40 years. Previously, little was known about if and how reforestation occurs after volcanic events. Thanks to satellite imagery and scientific analysis, much has been learned about the dynamics of forest recovery and associated changes in carbon stocks.
