Tutupaca
About Tutupaca
Tutupaca consists of two dissected volcanic edifices, of which the southern appears more youthful. Collapse of the northern edifice produced a debris avalanche that traveled 7 km N. Postglacial lava flows are present, the largest of which originated from the saddle between the two edifices. Solfataric activity was noted in the Catalog of Active Volcanoes of the World. Based on morphological evidence, de Silva and Francis (1990) suggested that reported historical eruptions in the 18th and 19th centuries (listed in the Catalog of Active Volcanoes of the World) more likely originated from the more youthful-looking Yucamane volcano. Work by Samaniego et al. (2015) showed that activity in 1787-89 and 1802 CE originated at Tutupaca, and they considered the 1780, 1862, and 1902 reports to be valid as well.
