“…Zablocki (1976) detected positive SP anomalies corresponding to pit craters on Kilauea Volcano, Hawaii. Similar positive SP anomalies were also observed on Usu, Hokkaido Komagatake (Nishida and Tomiya, 1987), Soufrier (Zlotnicki et al, 1994a) and Piton de la Fournaise (Zlotnicki et al, 1994b) volcanoes. Recently, Ishido (1991) estimated the amount of subsurface hydrothermal fluid flow from equivalent electric current sources associated with SP anomalies observed on Izu-Oshima Volcano.…”

“…Repeat self-potential surveys of active volcanoes have been carried out in many areas during the last two decades; Kilauea (Zablocki, 1976), Etna (Massenet and Pham, 1985), Usu (Nishida and Tomiya, 1987;Nishida et al, 1996), Akita Yake-yama , Hokkaido Komaga-take (Matsushima et al, 1990), Soufriere (Zlotnicki et al, 1994), Unzen (Hashimoto and Tanaka, 1995), Tarumae (Miyamura et al, 1995), and Miyake-jima (Nishida et al, 1996). Obvious positive-polarity SP anomalies were often observed around volcanic vents or fissures where fumarole activity was taking place.…”

, annual self-potential (SP) surveys were carried out on Izu-Oshima, a small volcanic island. A terrain-related SP distribution of about -1 mV per meter of elevation was observed outside the caldera in all five surveys. Inside the caldera, SP increases from about -350 mV to near 0 mV (relative to the coastline) as the summit crater is approached, although negative anomalies of small spatial extent are manifest. Selfpotential inside the caldera decreased by about 100 mV between the March 1989 and the March 1990 surveys, which appears to be correlated with a significant decline in the degassing rate from the summit crater. After 1990, the SP distribution is quite steady along the entire survey line which extends from the west coast through the southern part of the caldera, and ends east of Ura-sabaku. Recently a postprocessor has been developed to calculate space/time distributions of electrokinetic potentials resulting from histories of underground conditions (pressure, temperature, salt concentration, fiowrate etc.) computed by multiphase multi-component unsteady geothermal reservoir simulations (Ishido and Pritchett, 1996). We applied this postprocessor to a simple two-dimensional model of hydrothermal activity in a volcanic island. The low potentials in areas of high elevation are reproduced in the model, and are caused by downflow of meteoric waters. The high potential centered at the summit crater is found to be produced by upflows of volcanic gas and vapor which diminish meteoric water downflow near the volcanic conduit.

“…(Corwin and Hoover, 1979). In past years, the SP method has been applied in a wide class of geological problems: mineral prospecting, detection and delineation of thermal sources in geothermal and volcanic areas and hydrogeological studies for groundwater investigations (Zlotnicki et al, 1994;Loddo et al, 1996;Di Maio et al, 1996;Revil et al, 2002). In landslide areas, spatial and temporal measurements of the SP field may provide information on dynamic aspects of the hydrogeologic conditions within the landslide body (Bogoslovsky and Ogilvy, 1977;Coppola et al, 1994;Patella et al, 1995;Sharma, 1997;Gallipoli et al, 2000).…”
