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 ...

Dizhen xuebao, 2023 基于四川省威远地区密集流动台站从2019年12月1日至2020年6月30日期间收集到的42个ML3.0—4.5中小地震事件，采用Hypo2000定位法进行精定位，并利用HASH （Hardebeck & Shearer）法反演得到其中31次地震的震源机制解，之后利用阻尼区域应力反演方法计算了研究区的应力场参数。结果表明：中小地震主要分布在威远背斜南翼SSE向墨林场断层的两侧，震源深度集中在10 km以内，均为浅源地震；震源机制解类型以逆冲型为主，断层错动类型较为复杂，根据震源机制解结果 ...

Dizhen xuebao, 2021 震后应急工作中地震影响场的判定和快速给出较为合理的地震烈度分布图，是震后应急救援的重要依据，对于政府了解灾情、部署工作以及估算灾害损失都尤为重要，所以本文以此为研究目的，力求震后快速给出准确的地震烈度分布图。本文收集整理了河北地区中强地震的实际等震线图，将其与加入了震源机制解影响参数的烈度衰减关系计算得到的理论等震线图进行对比。结果显示：随着震级的增大，由衰减关系计算得到的等震线图与实际地震等震线图在高烈度区（≥Ⅶ度）相似度更高。另外，根据震后24小时内余震频度的空间变化，对极震区理论等震线修正后 ...

Spatial distribution and focal mechanism solutions of the Wenchuan earthquake series: Results and implications [PDF]
Earthquake Science, 2011 We relocate the spatial distribution of the devastating 12 May 2008 Wenchuan earthquake and its aftershocks. The relocation database is obtained from 89 stations deployed by the China Earthquake Administration, including 54 525 seismograms from 1 376 local earthquakes over MS3.5 between 12 May 2008 and 3 August 2008.
