  Mount Pinatubo - Wikipedia, the free encyclopedia
Mount Pinatubo is an active volcano located on the island of Luzon in the Philippines, at the intersection of the borders of the provinces of Zambales, Bataan, and Pampanga.
Pinatubo is part of a chain of volcanoes which lie along the western edge of the island of Luzon.
Pinatubo was a known geothermal area before the 1991 eruption, and small steam explosions are quite common in such areas.

 Global Effects of Explosive Volcanism
Following the devastating eruption of Mt. Pinatubo in the Philippines in June 1991 there has been a resurgence of interest in the global effects of volcanism.
Pinatubo was the second largest eruption of this century and produced approxmately 10 cubic kilometers of rock and ash (called tephra by volcanologists).
If this unexpectedly large increase in the size of ozone hole is due to Mt. Pinatubo aerosols, we may possibly see a return to predicted ozone hole size changes in the next few years, as the Mt. Pinatubo aerosols fall out of the stratosphere.

 Pinatubo effects in the Arctic as derived from Airborne and Surface observations
Despite the fact that this distribution could not be corroborated, it is clear that a layer of volcanic aerosols in the stratosphere had extinction values of the same order of magnitude as those observed at mid-levels of the troposphere.
In every case, the Pinatubo aerosol size spectra were best represented by bimodal, lognormal distributions exhibiting a superposition of a monodisperse large-particle (volcanic) mode on a small-particle (background) mode.
The prolonged lifetime of Pinatubo aerosols in the Arctic probably resulted from the unusual dynamical and microphysical processes that resulted in a concentration of aerosols within the polar vortex.

The Pinatubo Aeta are part of bands residing in mountanous, forested ares of the archipelago from Luzon to Mindanao.
An interesting aspect of the Pinatubo Aeta is their continuing resistance to the acculturation process, and their ability to modify whatever they borrow from the outside to suit their own culture.
While the Pinatubo Aeta have been the recipient of both government and private help in the form of better medical facilities and the construction of several schools serving the literacy needs of both children and adults, they have also been victimized by government land-use policies.

 Mount Pinatubo Revisited: A Study of Lahar Erosion - Introduction
The Pinatubo deposits are subdivided into two general groups based on the lithology and age of emplacement: the "ancestral" and the "modern." The ancestral Pinatubo (+ 1 million to +35,000 years B.P.) is an andesite-dacite stratovolcano of mostly laval flows and breccia deposits of laharic origin.
Other factors contributing to the rapid erosion of lahars are: failure of lahar dams, secondary explosions produced by rapid vertical and lateral erosion of the pyroclastic flow deposits, and stream and river capture bringing deposits into new drainage systems.
The lahars from Pinatubo have resulted in loss of lives and damage to properties in areas surrounding the volcano.
