Mount Pinatubo is a volcano known for producing the second largest terrestrial eruption of the twentieth century. Pinatubo lies at the intersection of the borders of Zambales, Tarlac and Pampanga and was covered with lush forest growth prior to the eruption. It had also supported several thousand Aeta. The volcano's eruption in June 1991 caused the destruction of billions of pesos' worth in economic and property damage and the loss of 847 lives. Aside from the massive damage to the Philippine economy, the eruption also had world-spanning ramifications.

The violent explosion on the 15th  of June in 1991 broke away a big part of the top of the Pinatubo. The summit of the volcano collapsed into the under laying magma chamber. The result was an enormous depression, the caldera, with a 2.5 kilometre diameter! 
The new summit of the volcano was 145 meters lower than before the explosion.
