This is a false color image of Mount Pinatuba in the Philippines. In the June 1991 eruptions, the main crater was produced and the red shows the rougher ash deposits. The dark drainages are the dangerous mudflows, called "lahars", which are started by heavy rains and will be a major hazard in the area for many years.
