초록
Fault plane solutions in North Korea and the northern part of the Yellow Sea (37.5oN-40.5oN, 124.5oE-128.5oE)was studied for the earthquakes that occurred from November, 2008 to May, 2013. The analysis was based on the datacollected from seismic networks in Korea and China. Fault plane solutions were obtained from P and SH wave polaritiesand SH/P amplitude ratioes. Most earthquakes exhibited predominantly strike-slip fault characteristics with NNE-SSW orWNW-ESE nodal planes. The P-axes trends are mainly NE-SW or ENE-WSW direction in the northern part of theYellow Sea and inland area of North Korea except some areas in the Hwanghae province. Fault plane solutions and mainaxis of stress field in the study region were similar to those observed in the southern part of the Korean Peninsula.
