The eruption is featured in volcano and disaster documentaries: The eruption is also mentioned in the disaster film Volcano (1997). When even more highly gas-charged magma reached Pinatubo's surface on June 15, the volcano exploded, sending an ash cloud 40 km (25 mi) into the atmosphere. Up to 800 people were killed and 100,000 became homeless following the Mount Pinatubo eruption, which climaxed with nine hours of the eruption on June 15, 1991. In the middle of June 1991, Luzon, the largest island in the Philipines, was rocked by the eruption of Mount Pinatubo. It produced a column of ash and smoke about 19 miles high, with rocks and debris falling the same distance from the volcano. More than 840 people were killed from the collapse of roofs under wet heavy ash and several more were injured. On the 2006 documentary on hypothetical disaster scenarios, On the 2003 television special produced by the, This page was last edited on 14 December 2020, at 06:28. No seismic records were available at this time, but volcanologists believe 22:30 PST marked the end of the climactic eruption. The cloud over the earth reduced global temperatures. When Pinatubo erupted, it spewed out 7-10 cubic kilometers of ash that blanketed areas as far away as Manila in a coat of fine, gray ash. The eruption of Mount Pinatubo was the second-largest volcanic cataclysm of the 20th century, second only to a 1912 eruption on the sparsely populated Alaskan Peninsula. The events of the 1991 Mount Pinatubo eruption began in July 1990, when a magnitude 7.8 earthquake occurred 100 kilometers (62 miles) northeast of the Pinatubo region, determined to be a result of the reawakening of Mount Pinatubo. Clark Air Base was ultimately abandoned by the United States military because of the eruption, and Subic Bay reverted to Philippine control in November 1992 following the breakdown of lease negotiations and the expiration of the Military Bases Agreement of 1947. The ash that was ejected from the volcano mixed with the water vapor in the air to cause a rainfall of tephra that fell across almost the entire island of Luzon. Until a few years previously, nobody had even suspected it was still active. Almost all of the island received some wet ash fall, which formed a heavy, rain-saturated snow-like blanket. The 18,000 personnel and their families were transported to Subic Bay Naval Station and most were returned to the United States. Mount Pinatubo, a 1,760-m (5,770-ft) volcano in the northern Philippines, erupted in 1991 after being dormant for 600 years.

This eruption was the largest disturbance of the stratosphere since the eruption of Krakatau in 1883 (but ten times larger than Mount St. Helens in 1980). The eruption of Mount Hudson in Chile in August 1991 also contributed to southern hemisphere ozone destruction, with measurements showing a sharp decrease in ozone levels at the tropopause when the aerosol clouds from Pinatubo and Hudson arrived. Tephra fell over most of the South China Sea and ash falls were recorded as far away as Vietnam, Cambodia, Singapore, Malaysia and Indonesia. Humanitarian aid received due to the eruption is as follows: The aerosol cloud spread around the earth in two weeks and covered the planet within a year. The 1991–92 eruptions of Mount Pinatubo, Philippines, would affect a population in Central Luzon that was unfamiliar with and initially sceptical about volcanic hazards. On the same day, Typhoon Yunya, locally named Diding, struck the island, with its center passing about 75 km (47 mi) north of the volcano. The colors in this animation reflect the atmospheric height of the particles. The eruption lasted for nine hours and caused several large earthquakes which resulted in the collapse of the summit and the creation of a caldera. The result of Mt. Novarupta in Alaska. The greatest thickness of ash deposited 33 centimeters (13 inches) approximately 10.5 km (6.5 mi) southwest of the volcano.
