24.188°S, 68.054°W; summit elev. 6233 m

All times are local (unless otherwise noted)

During field observations between 15 and 27 November 1990 no eruptive activity was observed . . . . Reports of miners working SW of Pular (closer than the April witnesses, who were 75 km NE) suggest that the 24 April eruption never took place.

Geological Summary. 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.
