RECENT GEODETIC ACTIVITIES IN VRANCEA AREA FOR GEODYNAMIC INVESTIGATIONS - VRAGEO PROJECT
Abstract
VRAGEO Project - Integrated Seismic Hazard Information Platform for Vrancea Zone Surveillance Through Advanced Geospatial and In-Situ Methodologies пїЅ have as main objective to enable free and open access to seismic hazard information in Romania due to Vrancea source in support of GMES (Global Monitoring of Environment and Security) through the development of an operational framework, a set of supporting tools and advanced geospatial surveillance methodologies of Vrancea tectonic active region. Information derived from time-series satellite data will be used in synergy with in-situ monitoring data provided by geophysical, geodetic, geodynamic, electromagnetic, solar, seismic, meteorological monitoring networks of Romania. A component of this platform it is represented by geodetic information. Geodetic activities performed by TUCEB (TU of Civil Engineering Bucharest) пїЅ Research Centre for Space Geodesy, Photogrammetry, Remote Sensing and GIS (GEOS) are presented in connection with other similar or complementary research activities. GNSS network (10 epoch stations) from Targu Secuiesc пїЅ Tulcea traverse, part of previous INDEGEN project network was observed by GNSS in 2015. A second campaign was performed in 2016. GNSS permanent stations available in the area will be included in order to increase density of observed stations. A cross leveling line on the epicentral area (P123-P126) was observed for the first time by precise leveling, too. Gravity data are available for the same line. A combined velocity field was compiled from present and previous projects in the area.
