Abstract Many questions have been raised about the thermal-mechanical development of faults movement, passive margins based on the effects of plate-boundary interactions, lithospheric processes, and mantle activity, in addition to continental thinning and generally the heat beneath our feet. This study attempts to identify and describe the hot-cold spots deep inside the Earth by using the 2D tomography velocity images obtained from surface wave seismic interferometry and regional tectonic activities in different geological units of the Caucasus region continent-continent ongoing collisional-compressed edge of the Eurasian-Arabic plates. Furthermore, this study could be helpful in identifying and proper understanding of the location of hotspots as renewable energy resources (geothermal) in areas near tectonic plate boundaries, rocks, arcs, and sediment interactions. To conduct this, after the preliminary correction of the raw data, a generalized 2D linear inversion procedure has been applied to construct the surface wave tomography to generate group velocity maps in a period range of 5-70 seconds and grid spacing of 0.2º×0.5º. The digital records of 800 earthquakes (M≥4) have been collected over the Caucasus region and these signals, recorded during the period of 1999-2018, come from 45 three-component broadband and short-period digital stations.

This paper discusses the joint impact of catchment complexity in topography, tectonics, climate, landuse patterns, and lithology on the suspended sediment yield (SSY, t km−2 year−1) in the Caucasus region using measurements from 244 gauging stations (GS). A Partial Least Square Regression (PLSR) was used to reveal the relationships between SSY and explanatory variables. Despite possible significant uncertainties on the SSY values, analysis of this database indicates clear spatial patterns of SSY in the Caucasus. Most catchments in the Lesser Caucasia and Ciscaucasia are characterized by relatively low SSY values (<100–150 t km−2 year−1), the Greater Caucasus region generally have higher SSY values (more than 150–300 t km−2 year−1). Partial correlation analyses demonstrated that such proxies of topography as height above nearest drainage (HAND) and normalized steepness index (Ksn) tend to be among the most important ones. However, a PLSR analysis suggested that these variables’ influence is likely associated with peak ground acceleration (PGA). We also found a strong relationship between land cover types (e.g., barren areas and cropland) and SSY in different elevation zones. Nonetheless, adding more gauging stations into analyses and more refined characterizations of the catchments may reveal additional trends.

The article deals with changes in ethnic structure in 13 political units of the North and the South Caucasus resulting from societal processes going on after the last 1989 Soviet census and illustrated by the outcome of censuses held in 1999–2005. The study deals with changes in population share of titular groups, Russians and other ethnic groups, with changing urbanization level and general regional population growth. It also makes an assessment of substantial changes in the ethnic structure in selected territories in connection with political and economical factors influencing the post-1989 development of the region and its ethno-territorial entities.
