In mid-April, 1991, Mt. Pinatubo, a volcano located on the island of Luzon, Republic
of the Philippines, began to steam. Many of us living on Clark AB didn't even know
there was a volcano 26 miles from the base, much less think it would erupt. Well, on
June 14-15, 1991, it did just that. After volcanologists determined it would blow at any
moment, the entire population of Clark AB (about 15,000 people), minus several hundred Security Police and
other key personnel, evacuated Clark AB for Subic Bay Naval Station on June 9th.
Here are several pictures of this huge eruption, which was several times LARGER than the Mt. St. Helens eruption of 1980.
