Abstract
Seismic ground response analyses and simplified determinations of fundamental periods of soil profiles were conducted for nine sites of the Greek coastal city of Kalamata which was struck by two destructive small epicentral distance earthquakes in September of 1986. The response analyses were performed by using the computer program LUSH here as the fundamental periods were determined by applying simplified methods suggested in recent literature. The dynamic soil properties needed in all calculations were obtained by in-situ and laboratory testing. The results of all analyses showed differentiation of response from site to site in terms of both frequency content and intensity of motion. Furthermore, the calculated fundamental periods fell within the period band of strong motion for all nine sites. It is concluded that local soil conditions have affected appreciably the ground surface response and may offer an explanation for the non-uniform earthquake damage distribution in some portions of the city.
