This study presents an analysis of seismic cutoff depth and heat flow field of the Fennoscandian Shield. Altogether 4190 earthquake events from years 2000-2015 in Finnish and Swedish national catalogues have been applied for this purpose. To model the heat flow field, 223 values from both countries and their neighbouring areas were used to find out if any correlation between the maximum earthquake focal depth (cutoff depth) and surface heat flow exists. Because heat flow and cutoff depth appear unrelated, it seems evident that regional variations of heat flow are caused by shallow lying variations (i.e., in upper crust) in heat production instead of deeper sources. Therefore one-dimensional layer models with temperature-dependent thermal conductivity are functional for the shield area.
