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 process...

The northern latitudes have warmed by about 0.8 C since the early 1970s, but not all areas have warmed equally. Eurasia shows an overall warming trend, while North America exhibits warming at a lower rate and even a slight cooling trend during the last 50 years in the Eastern USA. We analyzed a recently developed satellite normalized di erence vegetation index (NDVI) data set (July 1981 to Dece...

Afghanistan sits on the junction between the Indo-Australasian and Eurasian crustal plates and is composed of a series of terranes (Figure 1) that broke away from the main Gondwana supercontinent before colliding with and being accreted on to the Eurasian plate. The accretionary events began in the Cretaceous and have continued until recent times. The Herat or Hari Rod fault, which runs E-W acr...

The geographic distribution of genetic variation reflects trends in past population migrations and can be used to make inferences about these migrations. It has been proposed that the east-west orientation of the Eurasian landmass facilitated the rapid spread of ancient technological innovations across Eurasia, while the north-south orientation of the Americas led to a slower diffusion of techn...

The Middle East region represents a key site within the Tethyan domain where continental break-up, collision, backarc extension and escape tectonics are kinematically linked together. We perform global mantle circulation computations to test the role of slab pull and mantle upwellings as driving forces for the kinematics of the Arabia–Anatolia–Aegean (AAA) system, evaluating different boundary ...

Abstract The presence of offsets, appearing at intervals ranging from 10s to 100s kilometres, is a distinct characteristic constructive tectonic plate margins. By comparison, boundaries associated with subduction exhibit uninterrupted continuity. Here, we present global mantle convection calculations that result in mobile lithosphere featuring dynamically derived exhibiting contrasting superfic...
