Self-Potential Studies in Volcanic Environments: A Cheap and Efficient Method for Multiscale Fluid-Flow Investigations

Figure 5

SP survey in Las Cañadas caldera (Tenerife, Spain). The SP maxima highlight the main hydrothermal systems of Teide and Pico Viejo volcanoes, as well as smaller hydrothermal systems at two former volcanic vents (Montaña Blanca and Montaña Rajada). Ground water infiltration is highlighted by self-potential minima at the Diego Hernandez (DH) buried caldera and at the NW rift fractures (NWR). Figure from [76].
