Climatic fluctuations as a significant contributing factor for volcanic collapses. Evidence from Mexico during the Late Pleistocene

► We related climate conditions and edifice sector collapses for Mexican stratovolcanoes during the Late Pleistocene. ► The combination of summer and/or winter pluvial conditions could have contributed to or triggered the failure of already unstable volcanoes. ► Fluid availability in the mass prior to a volcanic collapse largely increases the mobility of associated gravitational flows.
