The seismicity of Albania is primarily driven by the collision between the Adria microplate and the Albanian orogen. The Ionian fault zone, located in southwestern Albania, is characterized by NW-SE trending neotectonic thrust faults with oblique components. These faults are predominantly marked by NW extension and include pre-Pliocene overthrust faults subjected to pure compressive stress. Occasionally, these overthrust faults are intersected by NE-SW-oriented thrust faults. The Ionian overthrust fault zone exten...

On January 15, 2023 (at 21:37 GMT), a moderate Ms4.8 earthquake occurred 4km southwest of the Klosi area and 24km north of Tirana. It was felt over a larger area of northern and central Albania. The earthquake sequence extended along the Nderfushas-Petralb-Gurre e Vogel tectonic fault zone, which is exposed on the ground for a length of about 25 km. The region affected by the January 2023 sequence, along with the seismogenic region of the August 11, 2018, moderate Ms5.2 earthquake, forms a roughly northeast to sou...
