英文摘要	Numerous investigations of Parícutin volcano have been made since its formation during 1943–1952, but none has utilized geophysical techniques until now. This report summarizes the results of near-surface geophysical surveys conducted during 2017–2019, involving self-potential, ground-temperature measurements, and a 3D resistivity model of the scoria cone. Interpretation of the integrated data enabled the definition of the geometry of the eruption's feeder dyke and a better understanding of the near-surface spatter facies. These geophysical data also better characterized the buried morphology of a horseshoe-shaped crater produced by a cone collapse early in the eruption, as well as the contact between lava flows and overlying pyroclastic fallout deposits. Moreover, the measured conductivities detected several meter-scale zones of convective hydrothermal fluid circulation within the cone. Collectively, the data of this study demonstrate a powerful approach to discern the relationship between the internal structure of a monogenetic cone and its associated hydrothermal system. ©2020.
