Cordón del Azufre is in the center of this 22 May 2019 Planet Scope satellite image (N is at the top), located along the Chile-Argentina border. The darker lava flow originated from Volcán la Moyra, the youngest feature of the volcanic field, reaching 6 km to the W. The complex includes a N-S chain of four craters and numerous lava flows. · 写真: Satellite image courtesy of Planet Labs Inc., 2019 (https://www.planet.com/). · Wikimedia Commons

地質学的概要

Cordón del Azufre is a small volcanic complex straddling the Chile-Argentina border. The complex consists of a cluster of lava flows from vents on the NE side, wholly within Argentina, and a 5-km-long chain of vents along the border with Chile. An older andesitic-dacitic edifice with a 1.3-km-wide crater was mostly covered by younger Holocene andesitic lava flows. The youngest cone, 300-m-high Volcán la Moyra, was the source of fresh-looking blocky andesitic lava flows that descended 6 km into Chile and 3 km into Argentina.

Wikipedia の要約

英語版の要約

Cordón del Azufre is an inactive complex volcano located in the Central Andes, at the border of Argentina and Chile. It consists of three stages of volcanic cones and associated lava flows, and its activity is a consequence of the subduction of the Nazca Plate underneath the South American Plate. North of it are the dormant volcano Lastarria and the actively uplifting Lazufre region.
