In June 1991, the second largest volcanic
eruption of the twentieth century* took place
on the island of Luzon in the Philippines, a
mere 90 kilometers (55 miles) northwest of
the capital city Manila. Up to 800 people were
killed and 100,000 became homeless following
the Mount Pinatubo eruption, which clima
xed with nine hours of eruption on June 15,
1991. On June 15, millions of tons of sulfur
dioxide were discharged into the atmosphere,
resulting in a decrease in the temperature
worldwide over the next few years.
Mount Pinatubo is part of a chain of
composite volcanoes along the Luzon arc on
the west coast of the island (area map). The
arc of volcanoes is due to the subduction of
the Manila trench to the west. The volcano
experienced major eruptions approximately
500, 3000, and 5500 years ago.
