Mount Pinatubo
Mount Pinatubo is an active volcano located in Zambales Philippines. The height of the volcano before it erupted in 1991 is 1,745m and its current height is 1,485m. It erupted in 1991 after being dormant for 600 years. The volcano erupted again in 1992. The volcano erupted four times from June 12 to June 16, 1991, which released more than 20 million tons of debris into the stratosphere.
It killed 800 people and left around 50,000 people homeless. It affected around 215,00 acres of farmland and destroyed fishponds, river valleys, bridges, and villages. Volcanic ash silted river valleys, causing extensive flooding. The silting of river channels and trapping of rainwater in an area of 300 km2 that formed a lake called lake Pinatubo, now 10m deep. There are 500 structures permanently submerge under this lake including houses, churches, and schools. The 1991 eruptions are believed to be the major reason why temperatures dropped globally in 1993.
