Updated historical earthquake catalog of İzmir region (western Anatolia) and its importance for the determination of seismogenic source

Although destructive earthquakes have not occurred in the instrumental period except for 30 October 2020 Samos earthquake (Mw = 6.6), records show that there were significant caused great destruction İzmir and its surroundings historical period. However, it is yet clear which faults are causative these affecting surroundings. For this purpose, has been attempted to determine new geological, seismological environmental data by examining a large number of original sources, old international catalogs, other than existing national catalogs used seismicity studies Turkey. In context, local updated catalog was prepared immediate vicinity. The obtained from maximum intensity some region X. This means active vicinity potential generate up Mw 7.1 future. Details on strengthen possibility may generated located near city settlement. isoseismic maps created first time using data, point out highest seismic 178, 1688 1778 A.D. center nearby settlements indicate they concentrated at relatively small area Bay İzmir, tectonically hanging-wall Fault. most likely scenario, all damages observed be attributed western segment Fault (Balcova segment) since defined as only source around fault map Turkey, course, should verified performing detailed paleoseismological studies.
