In what country would you find Mt. Pinatubo, whose 1991 eruption was the largest in the last hundred years?
Mount Pinatubo Mount Pinatubo Mount Pinatubo (; ; ; ; ) is an active stratovolcano in the Zambales Mountains, located on the tripoint boundary of the Philippine provinces of Zambales, Tarlac and Pampanga, all in Central Luzon on the northern island of Luzon. Its eruptive history was unknown to most before the pre-eruption volcanic activities of 1991, just before June. Pinatubo was heavily eroded, inconspicuous and obscured from view. It was covered with dense forests which supported a population of several thousand indigenous Aetas. Pinatubo is most notorious for its Volcanic Explosivity Index (VEI) 6 eruption on June 15, 1991, the second-largest
Mount Pinatubo Naval Base Subic Bay was south of Pinatubo, and the extent of Clark Air Base was just east of the volcano's summit. The volcano is near to about 6 million people. Mount Pinatubo's summit before the 1991 eruption was above sea level, only about above nearby plains, and only about higher than surrounding peaks, which largely obscured it from view. It is part of a chain of volcanoes which lie along the western side of the island of Luzon called the Zambales Mountains. Pinatubo belongs to the Cabusilan sub-range of the Zambales Mountains, which consists of Mt. Cuadrado, Mt. Negron,
