GPS probes the kinematics of the Vrancea Seismogenic Zone

Abstract

In late 2001, the Surface Behavior and Dynamical Units of the Southeast Carpathian Tectonics (SUBDUCT) program was initiated by the Netherlands Research Center for Integrated Solid Earth Sciences (ISES), together with the faculty of geology and geophysics at the University of Bucharest, and the (Romanian) National Institute for Earth Physics.

The aim of this program is to monitor, analyze, and interpret the surface motions occurring in response to active crust-lithosphere dynamics of the southeast Carpathians in Romania (Figure 1), using the Global Positioning System (GPS). For this region, observations of surface kinematics constitute a new and independent data source. In combination with other information, mainly obtained by geologic and geophysical studies, surface motions may help to unravel the intriguing tectonics of the region. Particularly SUBDUCT focuses on the dynamic processes of the Vrancea high-seismicity region.
