Pular

성층화산 · Chile · 6233m

Pular is the 12-km-long volcanic ridge below the center of this 29 October 2018 Planet Scope image (N is at the top; this image is approximately 41 km across). The lava flows to the W are at El Negrillar. The edifice contains Cerro Pular at the NE end and Cerro Pajonales at the SW.

지질학적 요약

Cerro Pular on the NE end and Cerro Pajonales on the SW form a 12-km-long volcanic ridge NE of Socompa volcano that is mostly pre-Holocene, but may have experienced some more recent activity. The chain lies NW of the Salar de Pular, about 15 km W of the Argentinian border. Extensive andesitic lava flows reach the lower flanks of the volcanoes, and about 10 craters are present. A major satellite vent W of the ridge appears to be the youngest feature of the volcanic complex. An uncertain small explosive eruption was reported in 1990, but the vent location was not known.

Wikipedia 요약

영어 요약

Pular is a volcanic massif in the northern Chilean Andes, in the Antofagasta Region north of Socompa volcano. It consists of the individual mountains Pajonales and Pular, which are among the highest mountains in the region and of great cultural importance to the neighbouring towns of Socaire and Peine. Pular and Pajonales have multiple volcanic craters and have produced lava domes. The mountains were active during the last three million years; whether there was any activity in historical times is unclear. The mountains are largely unglaciated in the present, owing to the dry climate, although groundwater originates on them. During the Last Glacial Maximum, glacial advances left a girdle of moraines around the massif.
