The World’s Worst Volcanic Eruptions

The World’s Worst Volcanic Eruptions As Measured by Death Toll
This list of the world’s worst volcanic eruptions includes only those whose death toll can be reasonably documented. The death toll from some of the worst eruptions in history can only be guessed. The eruption of Santorini in Greece in 1650 BC destroyed competely destroyed entire civilizations. Scientist also theorize that an eruption of Tuba around 75,000 years ago caused a volcanic winter that came close to wiping out mankind.
1. Mt. Tambora, Indonesia April 10 - 15, 1816 Death Toll: 92,000
The eruption of Tambora killed an estimated 92,000 people, including 10,000 from explosion and ash fall, and 82,000 from other related causes.
The concussion from the explosion was felt as far as a thousand miles away. Mt. Tambora, which was more than 13,000 feet tall before the explosion was reduced to 9,000 feet after ejecting more than 93 cubic miles of debris into the atmosphere.
The effects of the eruption were felt worldwide: 1816 became known as the “year without a summer” because of the volcanic ash in the atmosphere that lowered worldwide temperatures. It snowed in New England that June, and crop failures were common throughout Northern Europe and North America. As many as 100,000 additional deaths from starvation in these areas are thought to be traced to the eruption.
2. Mt. Pelee, West Indies April 25 - May 8, 1902 Death Toll: 40,000
Thought to be dormant, Mt. Pelee began a series of eruptions on April 25, 1902. The primary eruption, on May 8 completely destroyed the city of St. Pierre, killing 25,000. The only survivors were a man held in a prison cell, and a man who lived on the outskirts of the town. Several ships also were destroyed with all hands.
3. Mt. Krakatoa, Indonesia August 26 - 28, 1883 Death Toll: 36,000
The August 1883 of Mt. Krakatoa (Krakatua) destroyed 2/3 of the island, ejecting more than six cubic miles of debris into the atmosphere. The sound of the explosion was the loudest ever documented, and was heard as far away as Australia.
Interestingly, it’s probable that no one died in the initial explosion. The casualties all came from the resulting tsunami.
4. Nevado del Ruiz, Columbia November 13, 1985 Death Toll: 23,000
A small eruption of the Nevado del Ruiz volcano melted part of the volcano’s ice cap, creating an enormous mudslide that buried the city of Armero, killing 23,000.
5. Mt. Unzen, Japan 1792 Death Toll: 12,000 - 15,000
The eruption of Mt. Unzen was followed by an earthquake, which collapsed the east flank of the dome. The resulting avalance created a tsuanami which killed 12,000 to 15,000 in nearby towns.
6. Mt. Vesuvius, Italy April 24, AD 79 Death Toll: 10,000+
In one of the most famous eruptions of all time, Mt. Vesuvius erupted and completely destroyed the Roman towns of Pompeii and Herculaneum. The eruption, which is said to have lasted 19 hours, buried Pompeii in ten feet of volcanic ash. The intense heat—perhaps as much as 750 degrees—carbonized much of the organic material in the area. Many of the victims have been found with the tops of their heads missing—their brains having boiled and exploded.
7. The Laki Volcanic System, Iceland June 8, 1783 - February 1784 Death Toll: 9350
Nearly a year of constant eruptions created a dusty volcanic haze that created massive food shortages. Iceland suffered 9,350 deaths mostly due to starvation.
8. Mt. Vesuvius, Italy December 1631 Death Toll: 6,000
The notorious Mt. Vesuvius has erupted more than a dozen times since it destroyed the towns of Pompeii and Herculaneum. The 1631 eruption killed as many as 6,000 people when lava flows consumed many of the surrounding towns. Boiling water ejected from the volcanos added to the destruction.
9. Mt. Kelut, Indonesia May 19, 1919 Death Toll: 5,110
Most of the casualties apparently were the result of mudslides.
10. Mt. Galunggung, Java, Indonesia 1882 Death Toll: 4,011
