It injected a huge cloud of ash and sulfur dioxide, or SO2, high into the atmosphere, more than 30 kilometers (around 19 miles) above sea level, according to data from NASA satellites. The results show that all four volcanic eruptions produced a signicant amount of aerosols, increasing signicantly the AOT values over the volcanoes and nearby areas for periods ranging from a few weeks to a few months, with the Mount Pinatubo eruption having the greatest impact.

Nine months after the catastrophic 16 July 1990 M7.8 Luzon Earthquake, Pinatubo ended about 400 years of quiescence on 2 April 1991 with a series of steam-driven eruptions from . The ash and smoke cloud ejected by Mount Pinatubo in 1991 contained about twice as much matter as that thrown up by the El Chichn volcano (1982), making Pinatubo perhaps the largest eruption of the 20th century. 4 The ash that was released was used for farming to help the plants prosper. Seismographs were set up and began monitoring the volcano for earthquakes. , at the time of the Mount Pinatubo eruption the moderate CP El Nio of 1991 also transitioned to EP in 1992, similar to what we find in our CPE simulations. SELECTED IMPACTS. This caused extensive destruction to infrastructure and changed river systems for years after the eruption. The event left more than 200,000 people homeless. The UN document correctly indicates that volcanic eruptions sometimes fill the skies with ash or sulfur, dim the sun for years, and lead to measurable global cooling episodes. The Plague by Albert Camus | Quotes, Summary & Setting, Carbon Uses in Everyday Life: Lesson for Kids, African Tectonic Plate | Facts, Boundaries & Movement. Deaths, primarily caused by measles (31%), diarrhea (29%), and respiratory infections (22%), totaled 349 in the first 12 weeks.

Pinatubo injected about 15 million tons of sulfur dioxide into the stratosphere, where it reacted with water to form a hazy layer of aerosol particles composed primarily of sulfuric acid droplets. What experience do you need to become a teacher? Economic growth, which had been spreading to the region from Manila and which was slated for an extra boost from conversion of former U.S. military bases, has been weakened by the eruption. In the weeks after the eruption, hundreds more died as a result of disease in evacuation camps. More than 350 people died during the eruption, most of them from collapsing roofs. Many non-essential workers from the Clark Air Base and local residents had been evacuated by this time. Average global temperatures are normally cooler after significant eruptions because less solar radiation reaches the lower atmosphere in their aftermath. Pinatubo's eruption in 1991 reportedly emitted more than 15 million tons of SO 2 into the stratosphere that mixed with water to form tiny sulfate aerosols that reflect solar radiation into space reducing global temperature [5].
