Chaiten is a caldera volcano in southern Chile that had its first historic eruption on May 2, 2008 when it erupted violently. Ash fall and lahars during the eruption largely damaged the town of Chaitén, which had been evacuated as the eruption started.

Background
Chaitén is a small, glacier-free late-Pleistocene caldera with a Holocene lava dome located 10 km NE of the town of Chaitén on the Gulf of Corcovado. The north side of the rhyolitic, 962-m-high obsidian lava dome occupying the 3.5-km-wide caldera is unvegetated. Obsidian cobbles from this dome found in the Blanco River are the source of prehistorical artifacts from archaeological sites along the Pacific coast as far as 400 km away from the volcano to the north and south. The caldera is breached on the SW side by a river that drains to the bay of Chaitén, and the high point on its southern rim reaches 1,122 m. Two small lakes occupy the caldera floor on the west and north sides of the lava dome. Moreno (1985 pers. comm.) noted that the nearby volcano of Yelcho listed by the International Association of Volcanology and Chemistry of the Earth's Interior (1973) does not exist.---

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.

Chaitén Volcano FAQ
+When was the last eruption of Chaitén volcano?
The last confirmed eruption of Chaitén occurred during 2008 - 2011.
+How often does Chaitén volcano erupt?
There are no known historic eruptions, but evidence from geologic records shows that it has had at least 5 eruptions over the past 10,000 years. This number is likely much higher because many past eruptions might not have left evidence recognizeable today and/or the volcano might not have been studied in too much detail. Using the available data, a very conservative estimate is that Chaitén volcano erupts every 2,000 years.
+How active is Chaitén volcano at present?
Chaitén volcano is occasionally active: Since 1900, it has had 4 eruptions, and been active during 4 years out of 126 as of now. This means, Chaitén has been in eruption one in 31.5 years on average. The last eruption was from 2008 until 2011 and ended 14 years ago.
+When was the largest eruption of Chaitén volcano?
The largest eruption known from the younger geological history of Chaitén volcano occurred around 3100 BC. It ranks as a sub-plinian eruption with a magnitude 4 on the VEI (Volcanic Explosivity Index) scale.
