Abstract

Based on the published GPS data for the Upper Amur region, the parameters of the tensor of strain rates are calculated. In particular, we obtain such parameters of the main rates and main directions of strains, maximum shear strain rates and its directions, dilatancy rate, and second invariant of the strain rate tensor. The obtained results indicate a high tectonic activity in the zone of interaction between the Eurasian and Amurian plates and Stanovoy geoblock. The zones of high-rate aseismic displacements are revealed. It is supposed that NE-trending faults will be activated at the contemporary stage at the boundary between the Eurasian and Amurian plates.
