Mt. Pinatubo’s summer 1991 eruption was the largest on Earth since 1912. Pinatubo's big eruption is also famous for having been successfully predicted by American volcanologists. The prediction and subsequent evacuation saved thousands of lives.
Located near the western margin of Luzon Island in the northern Philippines, Mt. Pinatubo is one of several subduction zone stratovolcanoes in the Luzon Volcanic Arc. Published information indicates that Pinatubo is 35,000+ years old and is composed principally of dacitic and andesitic rocks.
The mid-June 1991 eruptions from Pinatubo blanketed ash, pumiceous lapilli, and pumice over the surrounding countryside, including two American military bases (Clark and Subic Bay).
The "appetizer-scale eruption" seen here occurred on 12 June 1991, a few days before the main eruption, which occurred in the middle of the night.
