A New Method of Seismic Source Parameter Estimation of a Locked-Segment Cracking Event
Geofluids, 2022 Locked segments are widely present in the slip surface of large rock slopes and seismogenic faults of rock underground engineering. Each cracking occasion of the locked segment results in a seismic event.

Dizhen xuebao, 2023 利用国家地震台网和全球地震台网的宽频带远震P波波形数据，通过测定2014—2019年间国内MW≥6.0和国外MW≥6.5共105次浅源地震的辐射能量和能量震级，研究了震源机制解对辐射能量估计的影响。结果表明：① 震源机制不同导致地震能量辐射差异较大，其中走滑型地震对辐射能量的影响最大，对能量震级的平均影响因子为0.34，正断型地震对能量震级的平均影响因子为0.08，逆断型地震对能量震级的影响最小，平均影响因子为0.05；② 不同震源机制类型地震的差震级ΔM也不同，走滑型地震的ΔM为 0.31 ...

Broadband Waveform Modeling Over a Dense Seismic Network [PDF]
, 2006 We developed a "two-way" calibration technique for studying clustered events, particularly their mechanisms and rupture directivities. First, we demonstrate that the magnitude 4 events with known source mechanisms can be used to calibrate the path ...

Coda-derived source properties estimated using local earthquakes in the Sea of Marmara, Türkiye [PDF]
Solid EarthAccurate estimates of the moment magnitude of earthquakes that physically measure the earthquake source energy are crucial for improving our understanding of seismic hazard in regions prone to tectonic activity. To address this demand, a method involving
