In this paper, a neotectonic map with active faults, at a scale of 1:500,000, of the northwestern Greece is presented and discussed. The elaboration of the Neotectonic Map chiefly aimed at the identification, mapping and assessment of the faults in the region of Epirus, for the added purpose of assessing the area's seismic hazard. To this end, the related research was largely directed to the detailed study of the tectonic structures, which were classified as active, potentially active and non-active (or unknown age). It is noted that the activity of many old structures continues to this day, as shown by the Neotectonic analysis, in conjunction with the region's seismicity. The presence of extensive scree deposits on the hanging wall of many faults also indicates their re-activation. For the final compilation and presentation of the map, geological, geomorphological and seismological data were used and assessed. The objective of this map is to provide information about the neotectonic evolution of northwestern Greece.

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.
