How many times has Chaiten erupted?
The researchers found that Chaitén has erupted at least 26 times in the past 10,000 years. In addition to the 2008 eruptive event, three eruptions were noted between A.D. 600 and 850 as well as another in about A.D. 420 — suggesting an average eruptive recurrence interval of roughly 200 years over the last 1,000 years.
Why did Chaiten volcano erupt?
The eruption that started on May 2 was unexpected because Chaitén was thought to have been dormant. During an eruption, some volcanoes build a dome of lava. 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.
Where did the Chaiten volcano erupt?
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.
What damage did Chaiten cause?
The Chaiten ash traveled as far as South Africa, and at least one aircraft encounter was reported. Ashfall can also cause damage to buildings and roads, disrupt power, and contaminate water supplies.
What type of volcano is the Chaiten?
caldera volcano
Chaitén is a caldera volcano formed when the magma chamber beneath a volcano completely empties during an eruption, causing the summit to collapse into it. The collapse creates a circular depression. Prior to its May 2008 eruption, the volcano had been dormant for more than 9,000 years.
What is the size of Chaitén Volcano?
Chaitén volcano: View of an eruption column from Chaitén Volcano, Chile, photographed on May 26, 2008. The caldera is about 3 km (1.9 miles) in diameter from rim to rim. The knobby feature between the eruption column and the left rim is part of a lava dome that formed after the 7,400 BC eruption.
Where is the Chaitén plate?
Simplified plate tectonics cross-section showing how Chaitén is located above a subduction zone formed where the Nazca and South America plates collide. In this subduction zone melting produces magma bodies that rise towards the surface.
What happened to the town of Chaitén?
Within 10 days of the first eruption, lahars had overrun much of the town of Chaitén. The Chilean government later ordered the complete evacuation of the town, and is currently planning to relocate the town entirely. Chaitén is a major concern to both the airline industry and the neighboring country of Argentina.
What is the name of the volcano in Chile?
Chaitén and Michinmahuida: This astronaut photograph highlights two volcanoes located near the southern boundary of the Nazca-South America subduction zone in southern Chile. Dominating the scene is the massive Michinmahuida Volcano (also spelled Minchinmávida; image upper right).
