  • The probabilistic seismic risk in Seoul Metropolitan Area $(atitude도 37.0^{circ}~37.8^{circ} N, longitude 126.5^{circ}~127.5^{circ} E)$ based on all Korean earthquake data of MM Intensity equal to or greater than V is evaluated by point source method. The seismic risk estimated from all data turned out to be lower than that from the data since the Choseon Dynasty during which seismic data appear to be rather complete. The damaging earthquake of peak horizontal ground acceleration greater than 0.1g turns out to occur with 90% probability of being exceeded in 200 years and 500 years when the data since Choseon Dynasty and all data are used, respectively.
