Upper panel: vertical cross section of the 3-D resistivity model (original model) used as a reference (Piña-Varas et al. 2015). Lower panel: Schematic models of Tenerife magmatic system and modified resistivity models used for the phonolitic magma chambers study. a Tenerife magmatic system proposed by Martí (2008) (modified from Martí 2008); b volcanic system of Teide volcano composed of three phonolitic chambers (modified from Andújar et al. 2013); c resistivity model PHO-1, equivalent to the volcanic system proposed by De Barros et al. (2012); d resistivity model PHO-2, equivalent to the volcanic system proposed by Andújar et al. (2013)
