“…The station velocities near Arta (Fig. 1) also reflect the N-S extension of the Amvrakikos graben [11,45,46], so they will be left out in further analysis. Another notable exception in this kinematic field is the Hexagon-SmartNet station PAXO (Fig.…”

We identify the source of the Mw = 5.6 earthquake that hit west-central Epirus on March 21, 2020 00:49:52 UTC. We use synthetic aperture radar interferograms tied to one permanent Global Navigation Satellite System (GNSS) station (GARD). We model the source by inverting the INSAR displacement data. The inversion model suggests a shallow source on a low-angle fault (39°) dipping towards east with a centroid depth of 8.5 km. The seismic moment deduced from our model agrees with those of the published seismic moment tensors. This geometry is compatible with the Margariti thrust fault within the collision zone between Apulia and Eurasia. We also processed new GNSS data and estimate a total convergence rate between Apulia and Eurasia of 8.9 mm yr-1 , of which shortening of the crust between the Epirus coastal GNSS stations and station PAXO in the Ionian Sea is equivalent to ~ 50% of it or 4.6 mm yr−1. A 60-km wide deformation zone takes up nearly most of the convergence between Apulia-Eurasia, trending N318°E. Its central axis runs along the southwest coast of Corfu, along the northeast coast of Paxos, heading toward the northern extremity of the Lefkada island.

“…Accordingly, it has been widely used to evaluate the level of tectonic activity in a specific region (e.g. Alipoor et al, 2011;Mahmood & Gloaguen, 2012;Ntokos, Lykoudi, & Rondoyanni, 2016;Wu et al, 2014).…”

In the Ioannina basin, thick lacustrine sediments-Pl.l (clays, marls, clayey silts, lacutrine limestones) including lignite layers [93] In the Subpelagonian Zone, towards the Pindos Zone, a large trough was formed during the final orogenetic activity of Upper Eocene age, in which very thick molassic sediments were deposited during Oligocene-Middle Miocene.…”

This paper presents the geological structure of the entire region of northwestern Greece (Epirus). Four geotectonic zones (Subpelagonian, Pindos, Gavrovo, and Ionian) develop in this area, overthrusting one another, their compression axes trending NE-SW. Normal, reverse, and strike-slip faults with main directions NNW-SSE, NE-SW, and E-W have influenced the geological formations. In the context of this paper, the results of all previous, relevant studies were considered, summarized and reviewed, in order to provide a brief historical recursion and present some of the most important discoveries made in the area, from 1840 until present. All these results were evaluated and combined, the geological formations were grouped according to their characteristics and field work enabled the confirmation or addition of new data, which led to the compilation of a new geological map, using GIS techniques, for the improved visualization of the geological and tectonic structure of northwestern Greece. This map illustrates a lot of new data, based on detailed geological-tectonic mapping, depicting the precise boundaries of the geological formations, detecting of Neogene and Quaternary sediments and evaluating fault activity. The knowledge and illustration of an area's geological structure constitute a dynamic tool for further scientific research and economic development.
