APOD 4.2

This is an image of the Volcano Tungurahua which sometimes erupts spectacularly. In the picture above, taken in 2006, the 5,000 meter high volcano is erupting, emitting dark plumes of ash and lava. As the lava flows down the side of the mountain, clouds intermingle with the dark ash. Located in Ecuador, Tungurahua has become active roughly every 90 years for the last 1,300 years.
