Based on the waveform data and seismic phase reports from the Xinjiang regional digital seismic network, the focal mechanism solution of Aheqi MS5.2 earthquake and some aftershocks are inverted using the CAP method. Meanwhile, the double-difference localization method is used to relocate the earthquake and its sequence. The results show that the strike, slip and rake are 259°, 44°, and 90° for nodal plane I, and those are 79°, 46°, 90° for nodal plane II, respectively, with a moment magnitude of MW4.76, and a depth of moment center of 5 km, which suggests that the earthquake is a reverse-type event. The relocation results show that Aheqi MS5.2 earthquake sequence spreads linearly in the NW direction and is perpendicular to the fault strike, and the depth is concentrated in 3-6 km. Based on this, we comprehensively analyze the historical seismic mechanism solution, geological and tectonic background, and conclude that the Suogedangtawu fault, which is located at the root of Keping thrust tectonic, is the seismogenic structure of this earthquake. This study can provide a certain understanding of the seismic mechanism of strong earthquakes in the contact zone between south Tianshan orogenic belt and Keping thrust tectonic, and provide reference for regional earthquake trend analysis.

基于新疆区域数字地震台网波形资料和震相报告，采用CAP方法反演2022-07-03阿合奇MS5.2主震和部分余震的震源机制，同时采用双差定位方法对该地震及其序列进行重新定位。结果表明，阿合奇MS5.2主震震源机制解节面Ⅰ走向259°、倾角44°、滑动角90°，节面Ⅱ走向79°、倾角46°、滑动角90°，矩震级MW4.76，矩心深度为5 km，表明此次地震为一次逆冲型事件。重定位结果表明，阿合奇MS5.2地震序列在空间上呈NW向线性展布，并垂直于断层走向，深度集中在3~6 km。在此基础上，结合该区历史震源机制解、地质构造背景等资料进行综合分析，认为位于柯坪推覆构造根部的索格当他乌断裂为此次地震的发震构造。本文研究能为南天山造山带与柯坪推覆构造接触带中强地震的发震机理提供一定的认识，为区域地震趋势分析提供参考。

基于新疆区域数字地震台网波形资料和震相报告，采用CAP方法反演2022-07-03阿合奇MS5.2主震和部分余震的震源机制，同时采用双差定位方法对该地震及其序列进行重新定位。结果表明，阿合奇MS5.2主震震源机制解节面Ⅰ走向259°、倾角44°、滑动角90°，节面Ⅱ走向79°、倾角46°、滑动角90°，矩震级MW4.76，矩心深度为5 km，表明此次地震为一次逆冲型事件。重定位结果表明，阿合奇MS5.2地震序列在空间上呈NW向线性展布，并垂直于断层走向，深度集中在3~6 km。在此基础上，结合该区历史震源机制解、地质构造背景等资料进行综合分析，认为位于柯坪推覆构造根部的索格当他乌断裂为此次地震的发震构造。本文研究能为南天山造山带与柯坪推覆构造接触带中强地震的发震机理提供一定的认识，为区域地震趋势分析提供参考。

Based on the waveform data and seismic phase reports from the Xinjiang regional digital seismic network, the focal mechanism solution of Aheqi MS5.2 earthquake and some aftershocks are inverted using the CAP method. Meanwhile, the double-difference localization method is used to relocate the earthquake and its sequence. The results show that the strike, slip and rake are 259°, 44°, and 90° for nodal plane I, and those are 79°, 46°, 90° for nodal plane II, respectively, with a moment magnitude of MW4.76, and a depth of moment center of 5 km, which suggests that the earthquake is a reverse-type event. The relocation results show that Aheqi MS5.2 earthquake sequence spreads linearly in the NW direction and is perpendicular to the fault strike, and the depth is concentrated in 3-6 km. Based on this, we comprehensively analyze the historical seismic mechanism solution, geological and tectonic background, and conclude that the Suogedangtawu fault, which is located at the root of Keping thrust tectonic, is the seismogenic structure of this earthquake. This study can provide a certain understanding of the seismic mechanism of strong earthquakes in the contact zone between south Tianshan orogenic belt and Keping thrust tectonic, and provide reference for regional earthquake trend analysis.

柯坪前陆推覆构造区中强地震的发震构造分析一直是该区研究的热点，尤其是震源区地震分布与逆冲断裂在深度剖面上的空间关系对发震机理尤为重要[1]。2022-07-03阿合奇MS5.2地震发生后，中国地震局地球物理研究所、USGS、GCMT等机构分别给出震源机制解，结果均表明此次地震的发震断层具有低倾角逆冲性质，但在震源深度上存在一定差异。吴传勇等[2]认为，柯坪推覆构造的滑脱面主要发育在5~20 km，而此次地震发生在研究相对较少的柯坪推覆构造后排索格当他乌断裂附近，其震源深度分布情况值得深入分析。因此，研究阿合奇地震发震构造可为深入分析柯坪前陆推覆构造区的地震活动性和区域地震趋势判定提供依据。
本文基于新疆地震台网震相到时数据，采用双差定位方法对阿合奇MS5.2地震序列进行重新定位，同时采用CAP方法反演地震序列中MS≥2.6地震的震源机制，并结合地质资料详细探讨阿合奇MS5.2地震可能的发震机理。

主要形成于新近纪的柯坪推覆构造位于塔里木盆地北缘西侧，东西长300 km，南北宽65~75 km，东西向有多排褶皱带被NS向皮羌断裂分割成东西2个部分[3]。受印度板块和欧亚板块持续碰撞，作为塔里木克拉通与南天山造山接触前端的柯坪推覆构造是天山地震带最为活跃的地区，其地壳缩短速率约为20 mm/a，变形量占天山总缩短速率一半以上，且西部缩短量大于东部[4]。柯坪推覆构造内部变形主要以挤压构造变形为主，底部滑脱面发育在地下5~20 km深度，许多学者对柯坪推覆构造的走滑变形进行分析，认为水平走滑受横向地层的限制，不具有较大的走滑变形[2]。阿合奇MS5.2地震震中位于迈丹断裂和索格当他乌断裂之间，前者以逆冲为主兼少量走滑，后者则以逆冲为主。其中，索格当他乌断裂整体呈NEE向展布，长度约为180 km，断裂性质以压性为主，地表断面倾向NNW，倾角70°~80°[2]。从整个柯坪前陆推覆构造来看，各排褶皱均仅残留背斜北翼，缺失南翼地层[5]。

2.1 资料
新疆区域地震台网台站在阿合奇MS5.2地震震中周边分布较少，震中距≤80 km的台站只有阿合奇台(AHQ)和柯坪台(KEP)。阿合奇MS5.2地震发生后，新疆地震局迅速在震中附近架设流动台L6501和L6513(图1)，为后续地震序列重定位提供了宝贵的数据支持。部分学者对柯坪块体的地壳速度结构进行研究，得到较为可靠的速度模型。Han等[6]联合反演体波和面波频散数据得到中国大陆岩石圈最新统一地震层析模型(USTClitho2.0)；而Crust1.0为全球三维地壳速度模型，分辨率为1°，可提供地壳各层的密度分布，本文将上述2种速度模型作为重新定位对比模型(图2)。研究区为沉积地层，速度结构变化平稳，考虑到CAP方法对速度模型和地壳横向变化的依赖较小，且模型中需要密度、S波速度等参数，本文选用Crust1.0作为CAP方法波形反演的速度模型。从图1可以看出，研究区观测台站少且分布不均，因此挑选更符合该区域的USTClitho2.0[6]速度模型，并采用双差定位法[7]进行重定位，以获得更准确的震中分布。
2.2 方法
本文采用HypoDD双差定位法[7]对阿合奇MS5.2地震及余震序列进行重定位。对于震源机制的反演，本文采用CAP方法[8]将宽频带数字地震波形记录分解为体波和面波2个部分，在给定的参数空间中进行网格搜索，计算并搜索理论地震波形与真实地震波形之间拟合误差函数最小的结果，以得到最优的震源机制解及其震源深度。经过筛选，最终得到14个地震的震源机制解结果，其中2.6≤MS＜3.5地震8个，MS≥3.5地震6个。

3.1 双差定位结果
基于新疆地震台网121个震相走时数据，按照震相数不小于8、最大相距不超过400 km进行筛选，分别得到P波和S波绝对走时数据5 744个和6 079个，同时设置P波和S波走时权重为1.0和0.5，最后基于USTClitho2.0速度模型获得76个定位结果，基于Crust1.0速度模型获得64个定位结果。从重定位结果数量来看，USTClitho2.0速度模型优于Crust1.0速度模型。为定量比较2种模型的重定位误差(残差)分布，采用一维正态分布概率密度函数对重定位结果进行精度分析，图3为2种速度模型在各个方向的定位误差和走时残差统计结果，可以看出，USTClitho2.0速度模型的重定位精度高于Crust1.0速度模型，其中USTClitho2.0模型在纬度、经度及垂直向的相对平均定位误差分别为0.15 km、0.38 km、0.54 km，表明重定位结果与初始定位结果在空间上的差异不大。综上所述，基于USTClitho2.0速度模型的重定位结果更为可信。
图4(a)为阿合奇MS5.2地震及余震序列重定位前后结果对比，整体来看，重定位后震中分布更为集中，主要分布在迈丹断裂和索格当他乌断裂之间，主震位于整个序列东南方向，更接近索格当他乌断裂。为更好地探讨地震活动与断层面的关系，沿地震序列长轴方向(NW向)取剖面AA′、垂直于长轴方向取剖面BB′(图4(b))。参照李安等[5]对整个柯坪推覆构造构造样式的刻画方法，绘制索格当他乌断裂在剖面AA′上的示意图(图4(b))。从剖面AA′来看，整个地震序列主要集中分布于发震断裂上端，主震震源深度为6 km，余震震源深度集中在3~5 km；从剖面BB′来看，余震序列位于主震西侧。从整个地震序列空间分布来看，重定位结果符合索格当他乌断裂的走向(NNW向)和倾角(70°~80°)参数，表明重定位结果较为可靠。
3.2 震源机制解结果
本文共计算得到14个地震的震源机制解结果，除个别地震滑动类型为逆断兼少量走滑外，其余均为逆断型，破裂类型显示出高度的一致性(图5)。从表1可以看出，节面Ⅰ走向以239°~279°为主，即NNE向，倾角以42°~58°为主，断面平缓，滑动角以80°~96°为主；节面Ⅱ走向以92°~110°为主，即近EW向，倾角以38°~52°为主，滑动角以80°~101°为主，两节面显示出纯逆冲型错动方式。P轴、T轴方位角变化较大，P轴倾伏角以1°~12°为主，T轴倾伏角以80°~88°为主，显示出近水平向的应力作用。结合阿合奇MS5.2地震序列和周边3次中强地震的震源机制解结果来看，均符合柯坪块体逆冲推覆的断层活动方式。
在计算阿合奇MS5.2地震震源机制解时，本文选取410 km范围内12个台站的波形数据，波形拟合时体波频带为0.05~0.12 Hz，面波频带为0.06~0.10 Hz，体波时间窗长为45 s，面波时间窗长为75 s。图6(a)为主震逆冲性质波形拟合结果，其中波形拟合相关系数大于0.75的部分占比达72 %，具有较好的拟合效果。图6(b)为该地震反演误差随深度的变化，在5.0 km时拟合差最小，并获得5 km矩心深度所对应的双力偶解：节面Ⅰ走向259°、倾角44°、滑动角90°，节面Ⅱ走向79°、倾角46°、滑动角90°，矩震级MW4.76。此外，通过计算阿合奇MS4.3地震震源机制解可知，节面Ⅰ走向269°、倾角42°、滑动角101°，节面Ⅱ走向74°、倾角49°、滑动角80°，矩震级MW4.36，震源最佳拟合深度为5.0 km。
对比USGS、GCMT等不同研究机构的结果可知，这2次地震事件的滑动类型均为逆冲型(表2)。图7为基于震源机制中心解方法[9]计算的阿合奇MS5.2地震震源机制解与其他结果对比，从最小空间旋转角来看，前4个震源机制解的旋转角范围在3.33°~11.72°，表明这4个震源机制解结果基本一致。最小空间旋转角可反映各种震源机制解结果的差异程度，与震源机制解反演过程中所用方法、速度模型、资料尺度等有关。从震源深度来看，各种机制解结果差异较大，本文2个地震的震源深度与梁姗姗等[10]的结果一致，均为5 km，这是由于在矩心深度反演过程中，高频性质波形对深度的敏感性优于低频性质。对于本文阿合奇MS5.2地震的重定位深度(6 km)要深于震源机制解结果(5 km)，原因可能为矩心深度反演反映的是地震所在破裂面的几何中心，而重定位深度反映的是地震初始破裂位置。
3.3 阿合奇MS5.2地震发震断层面分析
由于发震断层和震源深度对环境剪应力具有控制作用，因此本文在研究阿合奇MS5.2地震与构造应力场的关系时采用万永革[11]提出的逆断应力体系下产生的震源机制解类型及节面上剪应力和正应力特征分布方法。此次地震所在区域的应力场参数见参考文献[12]，其中主张应力轴走向为71.63°，倾伏角为78.82°；主压应力轴走向为171.62°，倾伏角为1.96°；应力比R=0.6。本文基于该方法获得阿合奇MS5.2地震在应力场约束下形成的震源机制解类型和不同节面上产生的相对剪应力和相对正应力(图8)。计算结果显示，应力张量在节面Ⅰ(走向259.0°，倾角44.0°)上的相对剪应力和相对正应力分别为0.994和-0.054，剪滑角为81.6°；在节面Ⅱ(走向79.0°，倾角46.0°)上的相对剪应力和相对正应力分别为0.986和-0.106，剪滑角为94.0°。2组节面相对剪应力接近1，处于剪应力极值区，表明阿合奇MS5.2地震发生在最大构造应力场释放节面上，是一次应力充分释放的地震事件；2组节面相对正应力均为负值，节面Ⅰ相对正应力值大于节面Ⅱ，表明在节面Ⅰ更易发生错动。综上所述，节面Ⅰ可能为此次地震的发震断层面。
3.4 阿合奇MS5.2地震与乌什MS7.1地震的关系分析
2024-01-23在阿合奇MS5.2地震东北约60 km处发生乌什MS7.1地震。从李瑞等[13]获得的柯坪块体周缘GPS水平速度场可知，阿合奇地震震源区速度(17 mm/a)大于乌什地震震源区速度(11 mm/a)，表明整个柯坪块体不断向盆山结合带的迈丹-沙依拉姆断裂推挤，反映应力场由南向北不断增强。从阿合奇地震序列震源机制解的应力轴方位角和倾伏角来看，阿合奇地震震源区整体表现为NW-SE向的近水平向挤压应力及近垂直向的拉张应力，而乌什地震震源区也具有相同的应力场性质[12]，表明阿合奇地震对乌什地震震源区的应力场具有挤压增强作用。本文采用关兆萱等[12]获得的乌什MS7.1地震序列震源机制解，并以其主震节面Ⅰ参数(走向244.62°，倾角46.19°，滑动角61.45°)作为接受断层参数，摩擦系数取0.7，计算获得乌什MS7.1地震在5 km深度的库仑应力分布。从图5可以看出，乌什地震震源区在NE-SW向的库仑应力处于加载状态(正值)，而阿合奇地震震源区位于该区域，表明迈丹-沙依拉姆断裂沿走向上一直处在应力持续加载状态，阿合奇地震的发生并未使迈丹-沙依拉姆断裂在NE-SW向的应力得到减弱。综上所述，阿合奇地震的发生对乌什地震可能具有触发作用。
4 发震构造分析

阿合奇MS5.2地震发生在距离阿合奇县城西侧约25 km处，震中北侧为高角度逆冲根部断裂(迈丹断裂)，以南则为低角度柯坪逆冲薄皮推覆构造，最近的断裂为推覆构造根部的索格当他乌逆冲断裂。李安等[5]基于人工地震剖面资料认为，柯坪推覆构造的多排褶皱冲断带具有统一的浅层滑脱面，集中在5~20 km。李瑞等[13]利用柯坪块体GPS数据分析得到迈丹断裂中段完全闭锁深度在10 km以上，并处在应力积累状态。重定位结果表明，阿合奇MS5.2地震序列分布集中在6 km以上，平面优势分布方向为NW向，沿走向剖面AA′余震分布在主震上端，沿垂直走向剖面BB′余震分布于主震西侧，为单侧破裂方式，表明发生在柯坪推覆构造根部的阿合奇MS5.2地震可能处在南天山西段与塔里木克拉通持续推挤的浅层滑脱面上。从柯坪推覆构造的地壳缩短速率来看，西段速率高于东段[4]，表明西段构造活动强于东段，而发生在柯坪推覆构造根部中段的阿合奇MS5.2地震序列分布于主震西侧和上端，进一步验证了重定位结果的可靠性。从14个震源机制解结果来看，震源破裂方式均为逆冲型，P轴走向(NW向)与断裂走向(NE向)垂直，且倾角很小，表明在柯坪推覆构造内部低倾角断裂的运动方式为近水平向的逆推滑动，这种运动方式可能是由柯坪推覆构造吸收帕米尔造山带远程推挤和塔里木盆地顺时针旋转产生的能量所致。从应力场作用下的发震断层面节面Ⅰ结果来看，断层面走向和倾角方向分别为NE向和NS向，这与索格当他乌断裂的地表出露特征一致。综合分析地震序列的重定位、震源机制解、断层面等结果，并结合周边断裂的断层面参数，初步认为具有逆冲性质的索格当他乌逆冲断裂为阿合奇MS5.2地震的主要发震构造。
5 结语
收起
本文基于新疆区域地震台网观测资料，利用双差定位方法对2022-07-03阿合奇MS5.2地震序列进行重新定位，获得76个重定位结果；同时采用CAP方法计算获得14个震源机制解结果，对比分析与其他机构震源机制解结果的差异，并结合断层地质资料初步分析阿合奇MS5.2地震可能的发震构造，获得以下认识：
1) 从地震序列双差定位结果来看，整个地震序列集中分布在6 km深度以上，优势分布方向为NW向，余震分布在主震上端和西侧，显示出单侧破裂方式。
2) 阿合奇MS5.2地震是柯坪前陆推覆构造根部逆冲断裂的一次超浅层、逆冲型地震事件，震源位于其底部的滑脱面上。
3) 阿合奇MS5.2地震主震震源机制解为：节面Ⅰ走向259°、倾角44°、滑动角90°，节面Ⅱ走向79°、倾角46°、滑动角90°，矩震级MW4.76，为近水平向的逆冲型地震。结合研究区地质资料，初步认为节面Ⅰ为断层错动面，推测其发震断层为索格当他乌断裂。
