Earthquake moment tensors and focal depths are crucial to assessing seismic hazards and studying active tectonic and volcanic processes. Although less powerful than strong earthquakes (M 7+), moderately strong earthquakes (M 5–6.5) occur more frequently and extensively, which can cause severe damages in populated areas. The inversion of moment tensors is usually affected by insufficient local waveform data (epicentral distance <5°⁠) in sparse seismic networks. It would be necessary to combine local and teleseismic data (epicentral distance 30°–90°) for a joint inversion. In this study, we present the generalized cut‐and‐paste joint (gCAPjoint) algorithm to jointly invert full moment tensor and centroid depth with local and teleseismic broadband waveforms. To demonstrate the effectiveness and explore the limitations of this algorithm, we perform case studies on three earthquakes with different tectonic settings and source properties. Comparison of our results with global centroid moment tensor and other catalog solutions illustrates that both non‐double‐couple compositions of the focal mechanisms and centroid depths can be reliably recovered for very shallow (⁠<10 km⁠) earthquakes and intermediate‐depth events with this software package.

gCAPjoint，一个用于以局部和远震波形对中等强度地震进行全矩张量反演的软件包

地震矩张量和震源深度对于评估地震危害以及研究活跃的构造和火山过程至关重要。尽管不如强地震（M 7+）强大，但中强地震（M 5–6.5）发生的频率更高，范围更广，可能在人口稠密的地区造成严重破坏。在稀疏地震网络中，弯矩张量的反转通常受局部波形数据不足（表观距离<5°⁠）的影响。为了进行联合反演，有必要结合本地和远震数据（表观距离为30°–90°）。在这项研究中，我们提出了广义的剪切粘贴联合（gCAPjoint）算法，以联合将全矩张量和质心深度与局部和远震宽带波形进行反演。为了证明其有效性并探索该算法的局限性，我们对三个具有不同构造背景和震源特性的地震进行了案例研究。将我们的结果与整体质心矩张量和其他目录解的比较表明，对于非常浅的地震（⁠<10km⁠）和中等深度的地震，震源机制的非双耦合成分和质心深度都可以可靠地恢复。该软件包。
