Thirty years ago, Mount St. Helens roared back into major activity with a massive eruption that leveled surrounding forest, blasted away over a thousand feet of the mountain’s summit, and claimed 57 human lives.
This short video shows the catastrophic eruption – and amazing recovery – through the eyes of the Landsat satellites, which have been imaging our planet for almost forty years.
