How did the Mount Pinatubo eruption affect people?
More than 350 people died during the eruption, most of them from collapsing roofs. Disease that broke out in evacuation camps and the continuing mud flows in the area caused additional deaths, bringing the total death toll to 722 people. The event left more than 200,000 people homeless.
What was the effect of the eruption of Mount Pinatubo in 1991?
Pyroclastic flows, lahars as well as the ashfall hazard all resulted in damage and casualties. The eruption cost $700 million in damage, $100 million of which was damage to 16 aircraft flying at the time of the eruption and $250 million in property with the rest a combination of agriculture, forestry and land.
What happened Mount Pinatubo when it erupted?
The world’s largest volcanic eruption to happen in the past 100 years was the June 15, 1991, eruption of Mount Pinatubo in the Philippines. Bursts of gas-charged magma exploded into umbrella ash clouds, hot flows of gas and ash descended the volcano’s flanks and lahars swept down valleys.
How extensive was the area affected by Pinatubo eruption?
The Mount Pinatubo eruptions buried some 18,000 ha of forest lands in ash fall of about 25 cm (Paladio-Melosantos and others, this volume). The heaviest concentration of ash fall was in the mountains of Botolan and San Marcelino in Zambales, in Porac and Floridablanca in Pampanga, and in Bamban and Capas, Tarlac.
| Social Effects | Economic Effects | Environmental effects |
|---|---|---|
| 58,000people had to be evacuated from a 30km radius of the volcano | Houses and bridges destroyed and needed replacing and Manila airport had to be closed | Volcanic ash is blown in all directions over hundreds of KMs, smothering fields and buildings. |
How did Mount Pinatubo effect the world?
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. In the case of Mount Pinatubo, the result was a measurable cooling of the Earth’s surface for a period of almost two years.
What happened after the eruption of Mount Pinatubo?
Within hours after Pinatubo’s eruption, a typhoon began dumping heavy rains on the area. The rainwater mixed with the loose volcanic material on the volcano’s slopes to form a dense, viscous mud with the consistency of wet cement and caused mudflows, called lahars, to race down Pinatubo’s slopes.
What happened after the 1991 Mt Pinatubo volcanic eruption?
Even after more than 5 years, hazardous effects from the June 15,1991, climactic eruption of Mount Pinatubo continue. Since the climactic 1991 eruption, ash deposits have also been remobilized by monsoon and typhoon rains to form giant mudflows of volcanic materials (lahars).
What type of landslide occurs in the eruption of Mt Pinatubo in 1991 that results to lahar?
Within hours of Mount Pinatubo’s explosive June 15, 1991, eruption, heavy rains began to wash the ash and debris deposited by this explosion down into the surrounding lowlands in giant, fast-moving mudflows called lahars.
How did the Mount Pinatubo eruption affect the atmosphere?
The Pinatubo eruption increased aerosol optical depth in the stratosphere by a factor of 10 to 100 times normal levels measured prior to the eruption. Consequently, over the next 15 months, scientists measured a drop in the average global temperature of about 1 degree F (0.6 degrees C).
