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.
