What type of eruption was Chaitén?
The recent rhyolitic eruption of Chaitén began in May 2008 (BGVN 33:04) and, according to Pallister and others (2013), comprised five major phases: (1) an explosive sequence (1-11 May 2008), (2) a transitional time that included ash plumes and lava extrusion (11-31 May 2008), (3) lava flows and dome growth (June- …
Why did the Chaitén volcano erupt?
Eventually, hot blocks of lava break away from the dome, triggering a fast-moving avalanche of hot volcanic ash, gas, and lava, called a pyroclastic flow. On May 6, the volcano began to erupt with pyroclastic material, forcing the complete evacuation of the town of Chaitén, said Reuters.
Is Chaitén still active?
However, recent studies have found that the volcano is more active than thought. According to the Global Volcanism Program, its last eruption was in 2011. The caldera rim reaches 1,122 metres (3,681 ft) above sea level….Chaitén (volcano)

What was the biggest eruption in 2008?
After more than 9,000 years of silence, Chaitén Volcano in southern Chile erupted on May 2, 2008. The plume of ash and steam rose 10.7 to 16.8 kilometers (35,000 to 55,000 feet) into the atmosphere, reported the Smithsonian’s Global Volcanism Program.
Which ocean has the ring of volcanoes?
More than half of the world’s active volcanoes above sea level encircle the Pacific Ocean to form the circum-Pacific “Ring of Fire.” In the past 25 years, scientists have developed a theory–called plate tectonics–that explains the locations of volcanoes and their relationship to other large-scale geologic features.
