The Division of Geophysics studies the solid Earth using magnetic, gravimetric, seismic, electrical and electromagnetic methods. The three main topics of research and education are:

Lithosphere geophysics aims to achieve a wide-scale knowledge about the structure, properties, composition, evolution and deformation of the continental lithosphere, particularly in the Fennoscandian Shield.

Mathematical geophysics covers methods for modelling and inversion, but also more general theoretical topics. One of the main tasks of geophysics is to reveal the structure of the earth quantitatively. In this task the field measurements are always the starting point. In addition, theoretical responses obtained by numerical modelling of realistic earth models are needed. Finally, by comparing the field data and the model responses, quantitative statement of the structure of the earth can be made by solving the geophysical inverse problem. Numerical modelling and inversion are an important area of geophysical research.

Applied geophysics includes research for various important economical and civil tasks, e.g., ore and mineral prospecting, groundwater mapping, civil engineering problems, geological and environmental studies. Environmental research is continuously growing in importance.
