First-Motion Focal Mechanism Solutions for 2015–2019 M ≥ 4.0 Italian Earthquakes [PDF]
Frontiers in Earth Science, 2021 A list of 100 focal mechanism solutions that occurred in Italy between 2015 and 2019 has been compiled for earthquakes with magnitude M ≥ 4.0. We define earthquake parameters for additional 22 seismic events with 3.0 ≤ M < 4.0 for two specific key zones: Muccia, at the northern termination of the Amatrice–Visso–Norcia 2016–2018 central Italy ...

Dizhen xuebao, 2019 基于2009年1月至2017年11月首都圈地区发生的8 061个地震事件的23 293条P波初动极性数据，采用改进的格点尝试法计算了首都圈地区单次地震的震源机制解和小震综合断层面解。在初步分析这些数据的基础上，利用计算得到的单次地震的震源机制解和搜集到的已有历史地震的震源机制解数据，运用线性反演法对首都圈地区构造应力场的时空变化特征进行了研究。结果显示：① 研究区的地震震源机制解类型以走滑型为主，正断型次之，这些地震震源机制解的P轴方位大都为ENE向和近EW向，与该地区的构造应力场方向基本一致 ...

Tectonic Implication of the 5th March 2005, Doublet Earthquake in Ilan, Taiwan
Terrestrial, Atmospheric and Oceanic Sciences, 2016 The 5th March 2005 earthquake doublet focal mechanism was determined as strike-slip faulting from Harvard and BATS moment tensor inversion. However, based on first motion polarities, the first shock has a normal focal mechanism (Wu et al. 2008a).

Dizhen xuebao, 2022 搜集了盈江及其邻区5组地震序列震源机制解并反演得到该区域的构造应力场。研究结果显示：盈江地区整体主压应力以NNE向为主，主张应力以ESE向为主；但其局部应力场不完全一致，沿苏典断裂分布的主压应力轴走向随着断裂走向由北向南延伸角度逐渐向北偏移，而盈江地区的西南部，其主压应力走向更偏向于东，这可能与大盈江断裂的横向拉伸有关。此外，本研究通过应力场反演识别出了5组地震序列震源机制解的主发震断层节面的走向、倾角、滑动角及发震断层的摩擦系数，为今后该区域的地震研究及地壳动力学变迁提供了参考。

2013 Seismic swarm recorded in Galati area, Romania: focal mechanism solutions [PDF]
Acta Geodaetica et Geophysica, 2016 An unusual seismic swarm started on September 23, 2013, close to Galati city, in Izvoarele region (Romania), and lasted until November 12, 2013. 406 earthquakes were recorded during several phases of seismic activity. The strongest events—a magnitude 3.9 earthquake, occurred on September 29, and two ML 3.8 shocks, occurred on October 3 and 4 ...

Application of simulated annealing to focal mechanism determination
, 2015 Simulated annealing (SA) is known as one of the efficient methods for global optimization. It allows for getting an optimal solution by jumping out of local minimum.
