Associate Professor Adam Simon co-taught a 10-day field school in the Chilean Andes with colleagues Philipp Ruprecht and Einat Lev from Columbia University, and Julia Hammer from the University of Hawaii. Students from Columbia University, the University of Hawaii, Universidad de Chile, and Universidad de Conception focused on the evolution of arc volcanoes and their relationship with metal ore deposits. The group spent most of their time at Volcan Quizapu, a crater on the flanks of the larger Cerro Azul volcano. Quizapu formed in 1846 during an effusive eruption of mafic to intermediate lavas. The volcano experienced many small eruptions in the early 20th century, and in 1932 there was a explosive Plinian eruption that ejected almost 10 cubic kilometers of dacitic magma and is the largest erupion in South America in recorded history.  The group used a drone to map lava flows and conducted two high-density sampling campaigns with the goal to assess spatial variability with the several-km long flows.  Among the highlights was being completely off the grid for the duration of the field school, which was wonderful mental therapy.
