Surface Velocities and Strain-Rates in the Euro-Mediterranean Region From Massive GPS Data Processing

In this work we present and discuss new geodetic velocity strain-rate fields for the Euro-Mediterranean region obtained from analysis of continuous GNSS stations. We describe procedures methods adopted to analyze raw GPS observations >4000 stations operating in Euro-Mediterranean, Eurasian African regions. The goal massive is monitoring Earth’s crust deformation response tectonic processes, including plate- micro-plate kinematics, geodynamics, active tectonics, earthquake-cycle, but also study a wide range geophysical natural anthropogenic subsidence, sea-level changes, hydrology. computational infrastructure, obtain three-dimensional field, which used spatial gradients horizontal strain-rates. then focus on region, where vertical velocities, gradients, that have time-series lengths longer than 6 7 years, are found be minimum spans provide stable reliable estimates components, respectively. compute field patterns kinematics along major seismogenic belts Nubia-Eurasia plate boundary zone Mediterranean region. distribution density our solution allow us estimate at scale ?27 km over large part southern Europe, with exclusion Dinaric mountains Balkans.
