Interpretation seismic and gravity data of Hazar Lake and surroundings, Eastern Anatolia

Abstract

The frequency-magnitude distribution of the earthquakes occurred in the city of Elazig and surrounding area was analysed with Bouguer gravity anomaly map. This region is located in Eastern Anatolia and tectonically very active and has a high seismic hazard risk. A complete set of 1550 earthquakes of Md ≥ 1 from 1 January 2010 to 28 February 2019 was used. The spatial mapping of frequency-magnitude distribution was produced. Outstanding variations in the b-value were detected with b ranging from b ≈ 0.7 to 1.3. The gravity anomaly were showed the lineaments and especially important geologic units. The results show that the accumulated stresses are high at the Pütürge segment in contrast to the fault, drawn in the south, represents the main thrust belt that runs through Hani-Lice and stretches to Çüngüş. The realtionships between two data, showing very high relation between them. The last activity on this area, the results of this study will give very clearly information to earthsciences.
