Coulomb Stress Analysis of The 19 April, 1938 Ms 6.8 Akpınar Earthquake (Kırşehir)

Abstract: In central Anatolia which was known as a quiescent region in terms of earthquake in general, somedevastated earthquakes have occured in several places of the region in the past. One of these earthquakesis the April 19, 1938 Akpinar (Kırşehir) earthquake (Ms 6.8) which occured on the Akpınar segmentlocated in northwest of the NW-SE trended Seyfe Fault Zone in the east of Kırşehir. After April 19, 1938earthquake, by using the data of the geological and geophysical studies done in the region, a Coulombstress model of the earthquake on the Seyfe Fault Zone has been obtained. The stress increase causedby the earthquake ranges between 0.137-4.5 bar. This has increased the seismic hazards around theresidential areas around the Seyfe Fault Zone such as Keskin (Kırıkkale) and Boztepe (Kırşehir) regions.
