The Eruption and Evacuation of Mt. Pinatubo

By: Theresa Lenon

Mt. Pinatubo is located on the island of Luzon in the Philippines. It is part of a chain of composite volcanoes called the Luzon Arc. After lying dormant for more than 500 years, the volcano began to show signs of erupting in 1991. From June 12 – June 15 Mt. Pinatubo produced one of the largest volcanic eruptions in the century. The effects of this eruption were felt world-wide when ash and gas from the volcano rose into the atmosphere, which caused more sunlight than usual to be deflected, resulting in a world-wide cooling of one degree Celsius.
