His scientific interests lie mostly in Seismology, Lithosphere, Paleontology, Structural basin and Tectonics. Frank Horváth works mostly in the field of Seismology, limiting it down to concerns involving Geothermal gradient and, occasionally, Mantle, Basalt and Volcanism. As part of one scientific family, Frank Horváth deals mainly with the area of Lithosphere, narrowing it down to issues related to the Sedimentary basin, and often Fault. Back-stripping and Inversion are among the areas of Structural basin where the researcher is concentrating his efforts. His study of Terrane is a part of Tectonics. His work is dedicated to discovering how Subduction, Geomorphology are connected with Crust and Geochemistry and other disciplines.
