한반도 남서부에서 발생한 미소지진의 진원 기구해 분석 = Focal Mechanism Solutions of Microearthquakes in the Southwestern Part of the Korea Peninsula

다국어 초록 (Multilingual Abstract)

Focal mechanisms were analyzed for the seven earthquakes which occurred in the southwestern part of theKorea Peninsula from 2001 to 2005. Grid searches are performed to fit distributions of P-wave first-motion polarities andSH/P amplitude ratios for each event. The focal mechanism solutions imply that most of the events have strike-slip sensedirections. This result is similar to the directions of the principal compressional axes for major earthquakes occurredaround the Korea Peninsula.......... focal mechanism solution, strike-slip fault, stress field. . : 2001... 2005... ... ..... ... 7. ..... .. .. .... ..... . .. .... ... ...
