[학위논문] 북한 지하 대규모 발파의 발파원 특성 및 한반도 주변 지각 속도 구조 연구
High-quality waveform data from regional seismic networks were essential in detection, location, and identification of two North Korean underground nuclear explosions conducted at the P'unggye-ri test site. The generated seismic waves are strongly affected by lateral variations in regional crustal structure surrounding the test site, which leads to difficulties in estimation of source parameters
