Was the eruption of Mount St Helens in 1980 was the greatest explosive eruption in the last two hundred years of world data?
The eruption of Mount St. Helens in 1980 was a significant event, but not the greatest explosive eruption in the last two hundred years. This title is often attributed to the eruption of Krakatoa in 1883, which had a larger impact on a global scale.
What was the most powerful and explosive volcanic eruption of historic time?
The eruption of Mount Tambora in Indonesia in 1815 is considered one of the most powerful and explosive volcanic eruptions in historic times. It is known as the "year without a summer" due to the global climate impact caused by the eruption.
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.
What can happen to global temperatures for several years after a volcanic eruption?
After a volcanic eruption, particularly a large one that emits significant amounts of ash and sulfur dioxide into the atmosphere, global temperatures can temporarily decrease. This occurs because the ash and sulfur particles reflect sunlight away from the Earth, leading to a cooling effect that can last for several years. The extent and duration of this cooling depend on the eruption's magnitude and the amount of aerosols released. Notable examples include the 1991 eruption of Mount Pinatubo, which caused global temperatures to drop by about 0.5 degrees Celsius for a couple of years.
Why was the eruption of Krakatoa in 1889 so explosive?
The eruption of Krakatoa in 1883 was so explosive due to the accumulation of high-pressure magma beneath the volcano, which eventually led to a catastrophic release of energy. The eruption was triggered by the collapse of the volcano's magma chamber, resulting in a series of powerful explosions that generated massive tsunamis and global climatic effects.
Is it possible for a volcano to change the earth's climate?
Yes. The sulfur emissions from a large, explosive eruption can trigger a global reduction in temperatures for several years.

What might happen if a major volcanic eruption every year?
Global temperatures might cool by several degrees

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.
What might happen if a major volcanic eruption occurred every year?
Global temperatures might cool by several degrees
Which event followed a massive volcanic eruptionand led to the cooling of global temperatures?
The event that followed a massive volcanic eruption and led to the cooling of global temperatures was known as a volcanic winter. The eruption can inject large amounts of ash and sulfur dioxide into the stratosphere, blocking sunlight and causing a temporary cooling effect on Earth's climate.
What is Mount Pelee's magnitude?
Mount Pelee's magnitude refers to the Volcanic Explosivity Index (VEI) of its 1902 eruption, which was estimated to be a 4. This VEI level indicates a significant explosive eruption that can cause widespread destruction and has a global impact.
What is mount tambora quiet or explosive?
The 1815 eruption of Mount Tambora was highly explosive. The largest in recorded history.
