Mount Merapi in Indonesia
In another false-color image from NASA, we see Mount Merapi on June 6, 2006, after a major eruption prompted the evacuation of more than 10,000 area villagers. NASA explains this image: "red indicates vegetation, and the brighter the red, the more robust the plant life. Clouds appear as bright, opaque white, and the volcanic plume appears as a dingy gray cloud blowing toward the southwest." Experts felt that powerful earthquakes in the region prior to the eruption may have contributed to the volcanic blast. Mount Merapi erupted again in late 2010, killing more than 350 people, and it is now in the preparation phase of another possible eruption.
