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 volcanic ash fall pelted the capital and La Aurora International Airport. The National Coordinator for Disaster Reduction (CONRED) declared a red alert for the communities near the volcano and recommended the evacuation of some of them. Noti7 reporter Anibal Archila, one of the first to cover the event, was reportedly killed by volcanic debris.
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.
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.
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.
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]
