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

Figure 3

Soil temperature measurements (top), self-potential values (middle), and electric resistivity tomography results (bottom) along Profile (see Figure 2). Compared to SP maps (of for example Figure 2), the data visualization in terms of single profile-values allows for a finer-scale analysis of the signal and a more meaningful comparison with other data types. PN: Punte Nere crater, PC: Pietre Cotte crater, and GC: Gran Cratere crater. This figure has been modified from [63].
