What were the effects of the eruption of Mount Pinatubo?
| 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. Because they scatter and absorb incoming sunlight, aerosol particles exert a cooling effect on the Earth’s surface.
What effects did Mt Pinatubo have on the environment?
The volcano’s eruption also had significant global environmental effects. Mount Pinatubo ejected roughly ten billion tons of magma onto the surrounding landscape and millions of tons of sulfur dioxide gas into the atmosphere, spreading an ash cloud over much of the earth.
What are the 5 effects of volcanic eruption?
Major health threats from a volcanic eruption Health concerns after a volcanic eruption include infectious disease, respiratory illness, burns, injuries from falls, and vehicle accidents related to the slippery, hazy conditions caused by ash.
What were the secondary impacts of the eruption of Mt Pinatubo?
Secondary Effect: Over 1 million farm animals died… either through starvation (grass was covered with ash) or from contaminated drinking water. Primary Effect: Roads were unusable and bridges were destroyed, so… people found it hard to escape and rescue and relief operations were difficult.
What did Mt Pinatubo destroy?
Several smaller lahars washed through the Clark Air Base, flowing across the base in enormously powerful sheets, slamming into buildings and scattering cars. Nearly every bridge within 30 km (19 mi) of Mount Pinatubo was destroyed….1. Resettlement.
| For whom | Amount (in pesos) |

| Lowlanders | 1.689 billion |
What is the positive effect of the 1991 eruption of Mount Pinatubo?
(U.S. bases have reverted to Philippine control since 1991.) Fortunately, scientists from the Philippine Institute of Volcanology and Seismology and the U.S. Geological Survey had forecast Pinatubo’s 1991 climactic eruption, resulting in the saving of at least 5,000 lives and at least $250 million in property.
What are the main effects of volcanoes?
Lava flows are almost always too slow to run over people, but they can certainly run over houses, roads, and any other structures. Pyroclastic flows are mixtures of hot gas and ash, and they travel very quickly down the slopes of volcanoes. They are so hot and choking that if you are caught in one it will kill you.
How did Mount Pinatubo effect the economy?
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.
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.
Is Mt Pinatubo expected to erupt again?
Pinatubo is not expected to erupt again for hundreds of years, assuming it keeps to its usual schedule. But if the mountain did blow today, Ewert said, monitoring it would be slightly easier, thanks to 20 years of technological advances.
Is Mt Vesuvius still erupting?
The eruption of Mount Vesuvius in 79 AD destroyed Pompeii. The chariot was spared when the walls and roof of the structure it was in collapsed, and also survived looting by modern-day antiquities thieves, who had dug tunnels through to the site, grazing but not damaging the four-wheeled cart, according to park officials.
What were some effects of Mount Pinatubo?
The volcano’s eruption also had significant global environmental effects. Mount Pinatubo ejected millions of tons of sulfur dioxide gas into the atmosphere, forming a cloud over the earth and decreasing average worldwide temperatures by almost 1 degree Fahrenheit for several years after the eruption.
How did the Pinatubo eruption affect the Earth?
At a Glance The 1991 eruption of Mount Pinatubo temporarily lowered global temperatures by nearly 1 degree. The temperature decrease was caused by massive amounts of sulfur dioxide released into the stratosphere. The intensity of volcanic eruptions is difficult to predict.
