It produced a series of tsunamis that devastated the region, killing around 36,000 people and destroying whole villages. Its airwaves travelled seven times around the globe. Krakatoa’s final eruption was four times more powerful than the largest bomb that humans have detonated. On the morning of 27 August, a series of massive eruptions tore the volcano’s walls apart. The eruption of the Indonesian volcano, Krakatoa, was one of the most violent eruptions in recent human history – completely destroying the island on which it resides. The caldera is 6km in diameter and 1100m deep. The summit caldera (volcanic crater) of Mt Tambora, photographed from space in 2009. In the two years after the explosion, the price of grain in Switzerland more than quadrupled. Thousands starved to death in China while typhus spread across Europe. Thanks to the enormous amount of SO 2 emitted, the world experienced a severe temperature drop that led to global crop failures. Upon entering the ocean, the force of the pyroclastic flow caused the creation of a series of towering tsunamis. It was the most powerful eruption in 500 years. On 10 April 1815, Tambora erupted sending volcanic ash 40km into the sky. Tambora is the deadliest eruption in recent human history, claiming the lives of up to 120,000 people. Here are 10 of the most devastating volcanic eruptions in human history: A United Nations study found that between 19, volcanic eruptions cost $152.6 billion in damages, roughly $7.6 billion a year.įrom an eruption’s magnitude to its death toll to its economic cost, the impact of a volcanic explosion can be enormous. While measuring the economic cost of ancient eruptions is largely theoretical, the costs of more recent eruptions are calculated by measuring the loss of infrastructure and the loss of income to people in the area. Volcanic eruptions can also be destructive for economies. The 2010 eruption of Eyjaflallajokull in Iceland resulted in the largest air-traffic shut-down since World War II, with over 100,000 flights cancelled, costing the airline industry worldwide an estimated US$1.7 billion. “Large eruptions can be devastating because of the temperature decrease, which can cause crops to fail over large areas”. “Crops can be buried by ash or animals poisoned by chemicals in the ash,” says Kelsie Dadd, an expert in the field of volcanology at the University of Sydney. Deaths do not just occur from the products of an eruption but can also occur because of loss of food. One of the most common ways to measure an eruption’s devastation is by calculating the estimated loss of life. While a good indicator, the magnitude of an eruption does not always infer its impact.
