After its initial eruption on May 2, 2008, Chile’s Chaitén Volcano remained active in the days and weeks that followed, releasing a near-constant plume and blanketing the region in ash. This false-color image uses thermal radiation to make an image of the volcano and its surroundings. The hottest area in this picture is at the lava dome in the volcano’s caldera. The purple-black plume blowing northeast from the summit is much colder.

Eruptions of Mount Oyama progressively covered the volcano's slopes with more and more ash over the last half of 2000.
