Application of the JMA instrumental intensity in Korea

摘要: In general, the seismic intensity deduced from instrumental data has been evaluated empirical relation between and PGA. From point of view that degree earthquake damage is more closely associated with than observed PGA, JMA developed (JMA intensity) meter estimate real-time strong motion to obtain a correct damage. The purpose present study propose practical application in Korea. Since occurrence earthquakes scarce Korean Peninsula, there an insufficiency data. As result, were synthesized by stochastic procedure satisfy characteristics source crustal attenuation Peninsula. Six engineering ground parameters, including intensity, determined relations parameters then analyzed. Cluster analysis classify into groups was also performed. result showed acceleration () could be classified similar group spectrum relatively distant CAV (Cumulative Absolute Velocity). It thought or can used as alternative criterion evaluation On other hand, equations for PGA prediction hazard derived functions moment magnitude hypocentral distance.
