Abstract

Plio-Quaternary tectonic activity of the Outer Northern Carpathians results from isostatic adjustment to diachronous nappe thrusting in the late Neogene, possible motions of various blocks in the Carpathian substratum and/or relaxation of horizontal remnant stresses along the fronts of thrust sheets. Tectonic activity of this area in the Quaternary has been relatively weak. The amount of excessive stress is only 11–13 MPa, the rate of present-day vertical movements varies from −1 to +2 mm/yr, and the average intensity of earthquakes ranges from IV to VI, Mercalli scale. Neotectonic phenomena seem to reflect isostatic rebound, suggested also by linear relationships between crustal thickness, heat flow and recent crustal movements.
