AVHRR satellite data depicting the thickness of aerosol optical products measured on May 28 to June 5, 1991, and again after the Pinatubo eruption on July 4 to July 10, 1991 (about 20 days following the major eruption). Ten days after the June 15 eruption the aerosol cloud formed a nearly continuous band that stretched 11,000 km from Indonesia to Central Africa. Image Credit: Larry Stowe. NOAA/NESDIS Office of Research and Applications 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:
