The earliest historical accounts of eruptions from the Mocho-Choshuenco complex may be those in Alonso de Ovalle's map Tabula Geographica Regni Chile from 1646. Here Mocho-Choshuenco may be one of the mountains drawn as erupting volcanoes east of Valdivia. In Juan Ignacio Molina's map from 1795 Mocho-choshuenco appears erupting under the name of Volcán de Valdivia, but eruption shown in this map is probably that of 1759.
