Kinematic models of recent motion of the Earth's crust on the territory of Croatia, Slovenia and Bosnia and Herzegovina

Abstract

Based on relative height displacement grid models of the Earth's crust, related to the territory of the Croatia, Slovenia and Bosnia and Herzegovina, which were created by modelling of the benchmark height data contained in levelling networks of the Austrian precise levelling (APN), and First (INVT) and Second (IINVT) levelling of high accuracy, possibility of creation of uniformly accelerated or decelerated motion model and uniform motion model of Earth's crust is analyzed. Kinematic laws of straight-line benchmark height motion has been applied to the values of Earth's crust height displacements that are associated with the nodes in the grid models of relative height displacements created between explicit epochs APN and INVT, and APN and IINVT. This application enabled determination of motion kinematic parameters associated with the grid nodes. Kinematic parameter's determination, structuring and including in a separate grid models, in analogy to the relative height displacement grid models, along with definition of basic kinematic equations of uniformly accelerated or decelerated motion and uniform motion of Earth's crust, allowed for the territory of the Croatia, Slovenia and Bosnia and Herzegovina kinematic models creation.
