Cerro Bayo Complex

Bayo Gorbea, Cerro

Gunung api kompleks · Chile-Argentina · 5413 m

The Cerro Bayo volcanic complex is along the Chile-Argentina border east of the Salar de Gorbea and is shown in this 21 October 2019 Planet Scope satellite image (N is at the top; the image is approximately 11.5 km across). A 430-m-diameter crater is visible at the summit of a scoria cone, and to the W are lobate lava flows with levees and pressure ridges.

Ringkasan geologi

Cerro Bayo is a complex volcano of partial Holocene age located along the Chile-Argentina border. An older center to the south contains a poorly preserved, 800-m-wide crater. A younger northern center along the national border has a well-preserved 400-m-wide crater and produced lava flows to the north and NE. The summit of the complex, located west of the border in Chile, is the source of two viscous dacitic lava flows that traveled to the north and represent the most recent activity of the complex.

Ringkasan Wikipedia

Ringkasan Inggris

Cerro Bayo is a complex volcano on the northern part border between Argentina and Chile. It consists of four overlapping stratovolcanoes along a north–south line. The main volcano face is located on the Argentine side, thought the summit of the complex is just west of the border, in Chile. The volcano is about 800,000 years old, but it is associated with ongoing ground uplift encompassing also the more northerly Lastarria and Cordón del Azufre volcanoes. The 5,401-metre (17,720 ft) high summit is the source of two viscous dacitic lava flows with prominent levees that traveled to the north.
