Özet

In Turkey, the record of earthquakes with the use of devices began in 1900. On September 20, 2020, an earthquake of Mw 5.1 happened near Obruk village of Nigde-Bor province (Central Anatolia, Turkey) and a swarm consisting of >100 aftershocks continued for one month. This swarm happened in an area where no seismic activity had been recorded before, according to the earthquake catalog covering the period 1900-2020. The area concerned is known for its monogenetic volcano sequences and is located immediately south of the active Hasandag volcano of the Central Anatolian Volcanic Province, Turkey. In this paper, we reported a volcano-structural interpretation of the seismic events, and evaluate the volcanic unrest possibilities related to the seismic activity on and around Hasandag.
