Top 20 Deadliest Volcanic Eruptions Since 1900
The confirmed death toll from the eruption of Mt. Ontake in Japan on September 27th now stands at 54 with 12 still missing. The event now ranks as the Earth’s 16th or 17th deadliest volcanic eruption since 1900. Here’s a brief review of the top 20 deadliest such events in the world since 1900. The death tolls are according to Wikipedia but other sources have differing figures.
1. Mt. Pelee, Martinique: 33,000 deaths in May 1902
A violent eruption and pyroclastic flow destroyed the town of Saint-Pierre, Martinique on May 8, 1902. It is said that there was only a single survivor left in the town: a prisoner held in an underground cell. There were, however, other survivors who lived on the outskirts of the city or who escaped by sea.

3. Santa Maria, Guatemala: 6,000 deaths in October 1902
Amazingly, the 3rd deadliest volcanic eruption in the world since 1900 occurred just months following the Mt. Pelee disaster. The Santa Maria Volcano is located near the town of Quetzaltenango in Guatemala and erupted with such force on October 24, 1902 that ash fell in San Francisco, California some 2,500 miles away. At least 5,000 residents in towns near the volcano in Guatemala died with about 1,000 additional deaths occurring due to disease following the eruption.

4. Mt. Kelud (Kelut), Indonesia: 5,115 deaths in May 1919
Indonesia has suffered the most catastrophic volcanic eruptions in modern history such as that of Krakatoa in 1883 that killed at least 36,000
and that of Mount Tambora in 1815 that killed over 100,000 and altered the Earth’s climate for years.
Since 1900, the deadliest Indonesian eruption was that of Mt. Kelud on the island of Java (not far from Surabaya) on May 19, 1919 when at least 5,000 were killed by lahars that overran villages surrounding the volcano. Read more about Mt. Kelud here.Gunung Kelud (Mt. Kelud, elevation 5,680’) erupted most recently in February this year (2014) threatening more than 200,000 people who live within a radius of just 6 miles around the volcano. Unlike 1919, there were no injuries as a result of the event.
