April eruption reports probably false

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.

Ash emission

Witnesses reported that "on 24 April at 1100 on a clear day with no clouds, a small eruption took place from Pular. It produced an explosion heard at El Laco (a Pacific Mining Company iron mine located 75 km NE; figure 3) and a column of black smoke that lasted just a few minutes above the summit, similar to those observed recently from Lascar." [but see 16:01] Geologists noted that the source of the 24 April eruption remains uncertain. Pular is believed to be Pleistocene in age.

The summit and flanks show signs of deep glacial erosion, including lateral moraines as low as 4,100 m. Pular is the northernmost member of the chain of volcanoes that bears the same name (Cordon Pular). None of the chain has had historic volcanic activity. Cerro Pajonales (24.20°S, 68.10°W), a satellite vent of Pular (5 km SW of the summit; figures 2 and 3), is a lava and dome complex believed to be Quaternary in age. Although evidence of glaciation has been noted on Cerro Pajonales, geologists believed it to be a more likely source of the recent activity.

Photo Gallery


The peaks with scattered snowfields near the center of this NASA Landsat image (with north to the top) are Cerro Pular on the NE and Cerrp Pajonales on the SW. The 12-km-long volcanic ridge lies NW of Salar de Pular (lower right) and NE of Socompa volcano, source of the lobate lava flows visible at the extreme lower left. Andesitic lava flows from the Pular-Pajonales chain overlie dacitic lava domes. An uncertain small explosive eruption was reported in 1990, but the vent location was not known.
