Subduction Parameters Controlling the Occurrence of Shallow and Deep Slow‐Slip Events (SSEs)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Slow‐slip events (SSEs) are transient aseismic fault‐slip phenomena that release tectonic stresses in a variety of tectonic environments, including subduction zones. In subduction margins, SSEs commonly occur along the plate interface at shallow (<20 km) and deep (30–60 km) depths.

基于泸定地区中小地震研究三维结构复杂性对震源参数反演的影响

Dizhen xuebao
以结构复杂且地震活动频繁的四川泸定地区为例评估三维速度结构复杂性对波形拟合方法反演震源参数的影响。首先采用谱元法合成2009—2019年泸定地区MS≥3.5地震的三维理论波形，然后对多个川滇地区一维模型进行测试，利用波形拟合方法反演合成波形的震源参数，结果表明在0.02—0.1 Hz滤波频段内，该地区三维速度结构的复杂性对MS3.5—5.0中小地震事件震源参数反演的影响较小，其中基于龙门山断裂带平均速度模型的的反演效果最佳。最后基于宽频带观测波形反演了2009—2019年泸定地区MS≥3 ...

Precise Temperature Measurements and Long‐Term Observations Revealed an Almost‐Constant Temperature Zone in a Vertical 700‐m‐Deep Borehole in the Aso Volcanic Region

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract To determine the subsurface temperature distribution and its relevance to groundwater flow in the deep subsurface, we repeated temperature depth profile measurements and conducted long‐term temperature observations in an ∼700‐m‐deep borehole penetrating the Futagawa fault along the Kiyama–Kashima graben in the Aso volcanic region, Japan from ...

Ecological Processes Underpinning Microbial Variability in Archean Granitoids Beneath the Deccan Traps: Evidence From Deep Drilling in Koyna, India

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Deep biosphere hosted by Archean granitoid basement of Deccan Traps showed depth‐wise microbial partitioning. Limited dispersion and variable selection control community assembly. Fewer abundant bacterial taxa were ubiquitous, while large numbers of rare taxa remained localized.

The western extension of Xiahe fault in West Qinling：Discussion on seismogenic structure of Qinghai Zeku MS4.9 earthquake in 2017

地震科学进展
The epicenter of the 2017 Qinghai Zeku MS4.9 earthquake was located near the SN-striking Riyueshan fault, while the focal mechanism solutions and the dominant arrangement of seismic sequence are inconsistent with the Riyueshan fault.

Seismogenic zone structure beneath the Nicoya Peninsula, Costa Rica, from three-dimensional local earthquake P- and S-wave tomography [PDF]

, 2006
The subduction plate interface along the Nicoya Peninsula, Costa Rica, generates damaging large (Mw > 7.5) earthquakes. We present hypocenters and 3-D seismic velocity models (VP and VP/VS) calculated using simultaneous inversion of P- and S-wave arrival
