As we all know, volcanoes are quite dangerous. We would have seen tons of volcanic eruptions.
Some are small, some are massive. In the end, the destruction caused is always worse.
VEI was discovered in 1980, which is very helpful for knowing the magnitude scales of earthquakes.
Since the last 10000 years, there are no volcanic eruptions that scaled 10 on the VEI scale.
Let Us See Some Of The Biggest Volcanic Eruptions In The World:
- Yellow stone volcano
- Huaynaputina volcano
- Krakatoa
- Santa Maria volcano
- Novarupta
- Mount Pinatubo
- Ambrym island
- Ilopano volcano
- Mount Thera
- Changbaishan volcano
- Mount Tambora
- Laki island
- Mount Pelee
- Mount Unzen
- Nevado del Ruiz volcano
- Yellow Stone Eruption:
The Yellowstone National Park is an active volcano that is always filled with visitors.
Seismologists and ecologists claim the yellow stone volcano to be one of the massive ones.
- Huaynaputina Volcano:
South America’s largest volcanic explosion was by the Huaynaputina volcano.
Mudflows were spread as far as the Pacific Ocean 75 miles far. Global climatic changes were one of the worse after-effects of the explosion.
The summer season faded after the explosion. After 1600 eruptions, the next 500 were crueler.
Ash from the explosion buried a 20-square-mile area to the mountain’s west.
- Krakatoa:
Rumblings of the last eruption have acted n for several months.
The explosive eruption of this Stratovolcano was heard thousands of miles away. Ash and dust flew farther away to many other countries.
The explosion also led way to a tsunami with a maximum of 140 feet.
34,000 people were killed in the tsunami. Agriculture was also affected during the period.
- Santa Maria Volcano:
The Santa Maria eruption in 1902 was one of the largest eruptions in the world.
After 500 years of dormancy, the volcano exploded massively, leaving behind a large crater, nearly a mile (1.5 km) across, on the mountain’s southwest flank.
The symmetrical Santa Maria volcano is part of a chain of Stratovolcanoes. In 1929, Santa Maria spewed forth a pyroclastic flow that killed nearly 5000 lives.
- Novarupta:
The eruption of Novarupta is one of the greatest eruptions on the Alaska Peninsula.
The explosion sent 3 cubic miles of magma and ash into the air. These particles fell over an area of 3,000 square miles. The after-effects were worse than expected.
- Mount Pinatubo:
It is a Stratovolcano which is located in a chain of volcanoes in Luzon.
The eruption ejected more than 1 cubic mile of ash, and dust into the air. This led to a column of ash that rose 22 miles up in the air.
The blast also spewed millions of tons of sulfur dioxide which is very harmful to the environment.
- Ambrym Island:
The Ambrym volcanic island is a part of the Republic of Vanuatu.
Ash and dust formed caldera which was 12 km wide.
In the 1894 explosion, six people were killed, four people were overtaken by lava flows.
- Ilopano Volcano:
The volcano only experienced an explosion twice in its history. The first known eruption was a dozy.
Trade routes were disturbed after the explosion. The summit’s caldera is one of El Salvador’s largest lakes.
- Mount Thera:
Mount Thera exploded with the energy of several hundred atomic bombs!
Geologists say that this explosion is one of the huge one’s ever happened. Tsunamis and temperature declines were the worse after-effects of the explosion.
- Changbaishan Volcano:
Changbaishan volcano is also known as the Baitoushan Volcano. The explosion of the volcano spewed volcanic material as far away as northern Japan, approximately 750 miles.
Geologists say that if another explosion takes place, severe damage might occur.
- Mount Tambora:
The explosion of Mount Tambora is the largest ever in history. The volcano is still super active and ready to explode anytime soon.
It is also one of the tallest peaks in the Indonesian archipelago.
The eruption reached its peak in April 1815. The nose is said to have reached Sumatra Island which is more than 1,200 miles away.
71,000 people were killed in the explosion, and climatic changes occurred instantly because of the heavy ash spread.
- Laki Island:
The Laki Island’s eruption was known t have impacts even after many years.
The Laki eruption lasted for 8 months which emitted 14.7km3 of lava. Poisonous gases were released and more than 60% of the crops were destroyed.
The volcano released massive amounts of SO2 which was the main reason why acid rain happened in the region.
Global temperatures also dropped gradually. More than10,000 people were killed in the disaster.
- Mount Pelee:
Mount Pelee is one of the great and deadly volcanoes in the Caribbean. The 1902 explosion of the volcano is well-known.
Until the 20th century explosion, the volcano was believed to be dormant.
On 8 May, Mt Pelee exploded with hot gas and volcanic debris. The entire city was destroyed.
Only 2 people survived out of 28,000 people.
- Mount Unzen:
Mount Unzen volcano in Japan is one of the deadliest volcanoes in the world.
The 1792 explosion of the volcano is popular throughout the world.
The explosion collapsed the dome of the volcano. it created a huge landslide and buried Shimabara city. It also flowed into the ocean and caused a tsunami too.
15,000 people died and the property damage crossed more than 17.4 billion yen.
- Nevado Del Ruiz Volcano:
Columbia’s Nevado Del Ruiz volcano is one of the largest volcanoes in the world.
In 1985, the explosion of the volcano occurred with a VEI sale of 3.
Though the volcano’s size is medium, the eruption was very large. The resulting mudflow buried the whole town of Armero. More than 20,000 people were killed.
Nevado volcanic explosion cost more than 1 billion dollars because of the explosion.
Conclusion:
These are some of the world’s largest and deadliest volcanoes.
The after-effects of each volcanic explosion are worse. There is no way to prevent these volcanic explosions unless we are geologists. Even geologists and scientists are trying hard with all the prevention and safety measures.
Let Us Stay Safe!
