The first volcano activity report published in 2018 noted ongoing seismic activity involving volcano-tectonic earthquakes . Seismic swarms were observed at Coropuna after the 2001 southern Peru earthquake and were possibly triggered by the earthquake . Observations of deformation of the volcanic edifice have shown that gravitational instability and soil water absorption result in movements of part of the volcano but as a whole Coropuna shows no evidence of volcanic deformation
