Breaking the Caribbean Plate: Subduction Initiation Beneath the Northern Margin of Panama

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The initiation of subduction zones is a poorly understood but core plate tectonic process. One unknown is how and under what conditions previously contiguous plates break. Here we present a comprehensive assessment of the Northern Panama Subduction Zone (NPSZ) where the Caribbean Plate is subducting to the SSW beneath Panama.

Bimodal Slip Segmentation of the SW Hellenic Megathrust Revealed by the Mw 6.8 Methoni Earthquake Sequence and Tomography

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract The influence of geological and structural heterogeneity on the megathrust slip behavior in subduction zones has been widely discussed for both the lower‐ and upper‐plates. In this work, we present OBS local earthquake tomography on the outer forearc domain of the SW Hellenic subduction zone performed with the aftershocks of the 2008 Mw 6.8 ...

Statistical characteristics and causal mechanisms of hydraulic fracturing induced seismicity in the Southern Sichuan Basin, China

Journal of Rock Mechanics and Geotechnical Engineering
In the Southern Sichuan Basin, China (SSBC), some moderate-sized seismic events (local magnitude ML ranging between 4 and 5) have affected the safe production of shale gas.

Investigating Stress Transfer and Fault Interaction in the July‑August 2025 Poso and Tokararu Earthquakes, Central Sulawesi, Indonesia

Annals of Geophysics
The July‑August 2025 earthquake in Central Sulawesi, which consisted of the Mw 5.9 Poso strike‑slip event and the Mw 6.0 Tokararu thrust event, offers new insights into stress transfer and fault interaction in a tectonically complex setting.

基于深度学习地震检测的2022年门源MS6.9地震序列活动性分析

Dizhen xuebao
本研究收集了2022年1月8日青海省门源MS6.9地震震中200 km范围内，主震前129天至震后235天的高密度观测台网资料，利用基于深度学习模型的微震检测定位对此次地震的地震活动性进一步进行解剖。使用深度学习拾取模型DiTingPicker从连续原始地震波形数据中自动检测事件并拾取震相，然后利用REAL模型进行震相关联，再利用Hypoinverse和HypoDD程序分别进行绝对定位和相对定位，最终得到2021年9月1日到2022年8月31日的地震目录3 637条 ...

Hypocenter Relocation in the Cianjur Region Using the Double-Difference Method

Journal of Physics, Conference Series
Indonesia’s seismicity results from the collision of the Eurasian, Indo-Australian, and Pacific plates, and the Cianjur region in West Java lies at the nexus of active faults and the southern Java subduction zone.
