[88] [89] As a result of the landslide, the height of the volcano was reduced from 338 meters to 110 meters. [90] 3 Ambae [91] Vanuatu 2018 During a series of eruptions, volcanic ash blackened the sky, buried crops and destroyed homes. Over the course of the year, the island's 11,000 population was forced to evacuate several times. [92] 3 Mount ...
In a volcanic eruption, lava, volcanic bombs, ash, and various gases are expelled from a volcanic vent and fissure. While many eruptions only pose dangers to the immediately surrounding area, Earth's largest eruptions can have a major regional or even global impact, with some affecting the climate and contributing to mass extinctions.
The 16 August 2006 eruption has been the most violent since activity commenced in 1999. This eruption was accompanied by a 10 kilometres (6.2 mi) high ash plume which spread over an area of 740 by 180 kilometres (460 by 110 mi), [ 15 ] depositing ash and tephra to the southwest of the volcano.
In volcanology, an explosive eruption is a volcanic eruption of the most violent type. A notable example is the 1980 eruption of Mount St. Helens . Such eruptions result when sufficient gas has dissolved under pressure within a viscous magma such that expelled lava violently froths into volcanic ash when pressure is suddenly lowered at the vent.
Misti is one of the most dangerous volcanoes in the world, as it lies less than 20 kilometres (12 mi) from Arequipa. The city's population exceeds one million people and its northeastern suburbs have expanded on to the slopes of the volcano.
It is regarded as one of the most dangerous volcanoes in the world because 3,000,000 people live near enough to be affected by an eruption, with at least 600,000 in the danger zone. This is the most densely populated volcanic region in the world. Eruptions tend to be violent and explosive; these are known as Plinian eruptions. [7]
Active volcanoes such as Stromboli, Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear. Some dangerous volcanoes in "populated areas" appear many times: Santorini six times, and Yellowstone hotspot 21 times.
