Abstract
Seismic risk maps in Korea are made using Korean historical and modern earthquake data. The risk maps made by several method are presented in contour line of vibratory ground motion(acceleration, velocity, and displacement). The method used are Kawasumi (1951), Kanai (1968), and Hsich et al (1975) method. The maps made by Kawasumi (1951) method represent the acceleration distribution ground and those by Kanai (1968) method show the acceleration, velocity, and displacement at bed rocks, The risk analysis by the method of Hsich et al (1975) shows the probability of acceleration at each of soft, medium and hard grounds in each tectonic province in Korea.
