Mount Pinatubo, Philippines, Erupted 26 Years Ago

Today Mount Pinatubo is relatively quiet, and about 300 meters shorter than it was before the eruption. This Landsat image pair shows the mountain several months after the eruption and more recently in 2017. The additional green near the summit indicates forest regrowth, but scars from fast-moving floods of volcanic ash and water are visible as pink stretches streaming away from the mountain. Called lahars, these floods affected more people than the eruption itself.
