Volcanism
Aside from the main crater, there are a few others, including the following cinder craters : La Resoloma Craters are below the western flank and the two known as Los Hornitos are on the lower southern flank of the stratovolcano.
During the outbreak in 1846 was built on the northern flank of the volcano of cinder cones Quizapu . This first eruption was mostly effusive and produced Dazite lavas . They poured east into the Estero Barroso valley and west into the valley of the Río Blanquillo river. At the same crater, however, one of the most powerful explosive eruptions of the 20th century occurred in 1932, when the ash cone expanded to a crater 600 to 700 meters in diameter and 150 meters deep. In the course of this eruption, 9.5 cubic kilometers of ash were released.
Further eruptions of the volcano: November 26, 1846 (emission of 5 cubic kilometers of lava), 1906, July 28, 1907, February 1912, September 8, 1914, 1916 to April 21, 1932, 1933 to 1938, April 1949, August 9, 1967 .
