The 1991 eruption sent up a cloud of ash 21km (13 miles) high. In volume this was 10 cubic km (2.4 cubic miles) of material.
The vast amount of aerosols and dust gradually spread through the stratosphere during the following year. Sulfur dioxide produced a global haze of sulfuric acid droplets. All this blocked out the sun. The amount of sunlight reaching the Earth's surface was reduced by 10%.
Temperatures in the northern hemisphere dropped by 0.5 C (0.9 F). At the same time temperatures in the stratosphere rose several degrees, because the dust and other particles there absorbed the sun's radiation (preventing it reaching the earth's surface). This cloud of aerosols from the explosion stayed in the stratosphere for three more years.
The eruption also lowered ozone levels. The winter ozone hole over Antarctica in 1992 was the largest ever.

How did the eruption of Mt Pinatubo affect the global temperature?
Sulfur dioxide released by the eruption formed tiny droplets of sulfuric acid in the upper atmosphere, which blocked out a small portion of the sun's light, slightly lowering global temperatures.
Is eruption of mt Pinatubo considered as historical?
Yes, the eruption of Mount Pinatubo in 1991 is considered a historical event because it was one of the most powerful volcanic eruptions of the 20th century. The eruption had significant global impacts, including lowering global temperatures and affecting regional climate patterns.
Why did the mount Pinatubo eruption result in global temperatures dropping almost two degrees?
The 1991 eruption of Mount Pinatubo released massive quantities of sulfur dioxide. This led to the formation of tiny droplets of sulfuric acid in the stratosphere. These reflected sunlight back into space, reducing global temperatures.
Did mount Pinatubo erupt before 1991?
Not in recorded history, but it had erupted before, otherwise there would be no Mount Pinatubo. Its last eruption before 1991 was about 600 years ago.
What is the magnitude of mt Pinatubo eruption?
Mt. Pinatubo is 1.6 miles wide. The last eruption took place on June 15, 1991. The volcano is located in the Philippines.

What is Mount Pinatubo?
Mount Pinatubo is a volcano on the island of Luzon in the Philippines. It is best known for its enormous eruption on June 15, 1991. This eruption was the second largest of the twentieth century.
What kind of mountain is mount Pinatubo?
Mount Pinatubo is an active stratovolcano located in the Philippines. Its eruption in 1991 was one of the largest in the 20th century and had global climatic impacts. It is characterized by its steep slopes and conical shape typical of stratovolcanoes.
Were there a lot of damage when mt Pinatubo erupted?
Yes, the eruption of Mt. Pinatubo in 1991 was one of the most significant volcanic events of the 20th century. It caused extensive damage to buildings, infrastructure, and agriculture in the surrounding areas, as well as impacting global climate patterns. The eruption released large amounts of ash and gases into the atmosphere, which led to air traffic disruptions and health hazards for local communities.
What were the affects after mount Pinatubo errupted?
The eruption of Mount Pinatubo in 1991 led to global cooling due to the release of ash and sulfur dioxide into the atmosphere, which blocked sunlight. The eruption caused significant environmental damage locally, including lahars (mudflows) and ashfall. It is considered one of the most powerful volcanic eruptions of the 20th century.
How many times did Mount Pinatubo erupt?
Mount Pinatubo erupted once in modern history, in June 1991. This eruption was a significant event, releasing a vast amount of volcanic ash and gases into the atmosphere, which had global climatic effects.
What global climate effects were caused by the eruption of Mount Ruiz?
