Where is Mount Pinatubo?

Mount Pinatubo is located on Luzon, the largest island in the Philippines, in the Zambales Mountains northwest of Manila. In June 1991 it produced one of the largest eruptions of the 20th century, sending ash high into the stratosphere and affecting global climate for a time. The eruption triggered lahars—dangerous volcanic mudflows—that continued to cause damage long after the main event. Today the volcano is a major case study in eruption forecasting and disaster response.
