Abstract

The paper discusses the possible source fault which resulted in the M (w) 6.4 Eskisehir earthquake on February 20, 1956, within the Anatolian complex. This is particularly important in view of the fact that Eskisehir, built mainly on alluvium, has a population of 500,000. The damage data were reviewed related to the number of people in the various villages affected. An empirical attenuation equation derived from Anatolian seismicity was applied to three suspected fault segments and the resultant ground motion rates were statistically compared with the damage data. A number of equally distributed suspected epicentres on each segment were considered. It is concluded that the earthquake was probably related to the Kavacik fault.
