The town of Dinar is located in the south-west Anatolian region and on the 38.06 longitude and 30.15 latitude, An earthquake of magnitude M(s) = 6.1 occurred on the Ist October 1995 at 5:57:18 p.m. local time, causing causalities and extensive damage to buildings in Dinar. The main reason why the structural damage was so heavy was due to the construction errors, and the downtown area being built on alluvial soils. The earthquake forces during the main shock were amplified by the poor dynamic characteristics of these soils thus resulting in excessive damage to buildings. A few days after the main shock, investigations started to determine the damage to the structures, and to identify design and construction errors. The response spectra of the main shock are calculated and the relationship between the strong ground motion and structural damage are determined. The aim of this study is to determine earthquake characteristics and soil properties in the vicinity of Dinar, to calculate the response spectra, and to present the results of field observations, office studies and records of the earthquake of 1 October 1995.
