The application of shallow electrical tomography to the study of hydrothermal objects of the Ebeko Volcano (Paramushir Island, Kurils).

Abstract

In this paper we present the data of the direct-current electrical resistivity tomography (ERT) using to study volcanic fumarole fields Ebeko (Paramushir Island of Kurils). The aim was to find shallow hydrothermal reservoirs and determine their dimensions and configuration. Buffer properties of these objects are regarded as one of the main reasons for the differentiation of gas compositions of different thermal fields with a single source of deep fluid. We obtained the 2D maps of the subsurface area up to a depth 20–40 m. We found shallow depth hydrothermal objects with highly mineralization.
