The results of complex studies of the northeastern fumarole field of the Ebeko Volcano (Paramushir Island) are presented. The geochemical study of the thermal sources and potholes evidences the complex composition of the solutions: the high contents of certain chemical elements in the sources cannot be explained only by leaching from the host rocks. To identify the structural features that can lead to accumulation of elements in the thermal solutions, the geophysical study of the northeastern fumarole field of the volcano is carried out by frequency sounding, electric tomography, and temperature surveying along the profile. As a result, the structure of the subsurface space of the thermal field, the structure of the feeders, and the presence of a phase barrier for fluid separation are revealed. The complex of studies makes it possible to explain some features of the geochemical composition of the thermal sources and to describe the evolution of the fluids in the upper segment of the section
