Spatiotemporal Variations of Focal Mechanism Solutions and Stress Field of the 2019 Changning Ms 6.0 Earthquake Sequence

Frontiers in Earth Science, 2022
The June 17, 2019, MS 6.0 Changning earthquake is the largest recorded event in the Sichuan basin, spatiotemporal variations of stress field may shed light on the seismogenic mechanism of the earthquake. We determined the focal mechanism solutions (FMSs)

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.

川南威远地区中小地震震源机制解及应力场特征

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 ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

震源机制和场地条件在河北地震影响场判定中的应用研究

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 ...

Seismicity associated with hydraulic fracturing in Changning shale gas field, China: Constraints from source mechanisms, stress field and fluid overpressure thresholds

Journal of Rock Mechanics and Geotechnical Engineering
Source properties and stress fields are critical to understand fundamental mechanisms for fluid-induced earthquakes. In this study, we identify the focal mechanism solutions (FMSs) of 360 earthquakes with local magnitude ML ≥ 1.5 in the Changning shale ...

Association Between Individualized Education for Kidney Replacement Therapy Modality Selection and Peritoneal Dialysis Initiation: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.
