The whole world was shaken by this volcano in 1991.
PHIVOLCS sees to it that they will not repeat their past mistakes in forecasting a volcanic eruption activity in the Philippines. Pinatubo is enough!
Nearly 20 million tons of sulfur dioxide were injected into the stratosphere in Pinatubo’s 1991 eruptions, and dispersal of this gas cloud around the world caused global temperatures to drop temporarily (1991 through 1993) by about 1°F (0.5°C). The eruptions have dramatically changed the face of central Luzon, home to about 3 million people.
About 20,000 indigenous Aeta highlanders, who had lived on the slopes of the volcano, were completely displaced, and most still wait in resettlement camps for the day when they can return home.
