地質学的概要
The Nevados Casiri compound volcano in Peru, also known as Paugarani, lies near the Chilean border ~25 km N of Tacora volcano. The trachytic and trachyandesitic complex consists of four volcanic edifices, with the youngest cone on the SE side. Two dark younger lava flows are SE of the most recently active cone, which has a well-defined summit crater. An older lava dome is located to the west. Sulfur has been mined on the NW and SE flanks.
Wikipedia の要約
英語版の要約Casiri, also known as Paucarani, is an about 5,650 metres (18,537 ft) high complex volcano in the Barroso mountain range of the Andes, in the Tacna Region of Peru. It consists of four individual volcanic edifices with lava domes; the southeasternmost edifice has been active during the Holocene, producing thick lava flows that have overrun moraines of Pleistocene age. The youngest lava flow has been dated to 2,600 ± 400 years ago. Although no historical eruptions are known, the volcano is considered to be potentially active and is monitored.
