Patio area at the Officer's Club at Clark Air Base as photographed on July 31. Pumice particles as large as 7cm in diameter fell at this location, 25 km east of the crater. Particles roughly 1.5 cm in diameter fell 33 km south-southwest (at Olongapo). Over 150 buildings were totally destroyed. Damage to Clark Air Base was estimated at $600 million. The eruption turned Clark Air Base and Subic Bay Naval Station (twice as far from the volcano) into wastelands buried in 15-30 cm of white ash. Vegetation was stripped and many buildings were merely twisted pieces of metal. Despite the widespread damage, all mission-essential personnel returned to Clark Air Base within 48 hours of the June 15 eruption. Image Credit: T.J. Casadevall. U.S. Geological Survey June 15, 1991 Pinatubo Philippines volcano Mount Pinatubo is an andesitic island arc volcano, located on the southwestern part of the island of Luzon in the Philippines. Prior to 1991, it had been dormant for more than 635 years. After months of rumbling, the volcano stirred to life on April 2, 1991. The next two and a half months were marked by generally increasing volcanic and seismic activity at the site. On June 15, a cataclysmic eruption began with a tremendous explosion. This slide set shows the early stages of the eruption phase, the cataclysmic eruption of June 15, and the effects and aftermath of the eruption. Subsequent calamities caused by the ash, pyroclastic flows, mud flows, and flooding are also depicted. Event Data:
