Co‐Seismic Deformation and Local Stress Evolution of the Philippines Earthquakes in July and October 2022 Revealed by InSAR and GNSS Observations

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract On 27 July and 25 October 2022, an Mw 7.0 earthquake and an Mw 6.4 earthquake struck Abra, northwest of Luzon, Philippines, respectively, with a time interval of less than 3 months and a distance of about 16 km. In this research, interferometric synthetic aperture radar (InSAR) was utilized to retrieve the co‐seismic surface deformation field ...

2021年固原震群重定位及发震构造分析

Dizhen xuebao
通过初至P震相定位法测定了2021年固原震群中ML≥3.0地震的震源深度，同时根据多阶段定位和微震匹配定位方法对该震群序列进行了重定位，基于Snoke方法和HASH方法计算了震群序列中ML≥2.8地震的震源机制解，并根据gCAP方法反演了震群中最大的地震即2021年6月22日固原ML3.6地震的震源机制解及矩心深度，确定了ML≥2.8地震基于各种方法所得震源机制的中心解，然后根据重定位结果拟合了断层面，最后初步分析了固原震群的发震构造。结果表明：微震检测到901次ML0.0以上地震事件 ...

Fault textures in volcanic conduits: evidence for seismic trigger mechanisms during silicic eruptions. [PDF]

, 2005
It is proposed that fault textures in two dissected rhyolitic conduits in Iceland preserve evidence for shallow seismogenic faulting within rising magma during the emplacement of highly viscous lava flows. Detailed field and petrographic analysis of such

Dynamical analogy between economical crisis and earthquake dynamics within the nonextensive statistical mechanics framework

, 2013
The field of study of complex systems considers that the dynamics of complex systems are founded on universal principles that may be used to describe a great variety of scientific and technological approaches of different types of natural, artificial ...

From Collision to Subduction: Thermal‐Kinematic Inversions Constrain Plate Boundary Structure and Dip‐Slip Activity in Southwestern New Zealand

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Constraints on three‐dimensional fault system geometry and kinematics are required to understand both long‐term tectonics and contemporary seismic hazard. In many cases, these parameters must be inferred from a combination of different data or analyses.

Asperities and barriers on the seismogenic zone in North Chile: state-of-the-art after the 2007 Mw 7.7 Tocopilla earthquake inferred by GPS and InSAR data [PDF]

, 2010
The Mw 7.7 2007 November 14 earthquake had an epicentre located close to the city of Tocopilla, at the southern end of a known seismic gap in North Chile. Through modelling of Global Positioning System (GPS) and radar interferometry (InSAR) data, we show

Fracture‐Assisted Pressure Solution Creep of Granite: An Example From the Mont Blanc Massif, Western Alps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Mont Blanc granite, as other deformed granites, has splitting properties attributed to two perpendicular planes: one formed by aligned fractures and the other by aligned micas in foliation planes. It is shown that this microstructure results from ductile deformation with stress‐driven dissolution of quartz and feldspar that passively ...

Quantifying Vein Network Permeability in Dehydrated Serpentinites Using Thermodynamics and Generative AI

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Fluids released from subducting hydrated rocks influence volcanism, tectonics, and geochemical cycling, but the mechanisms of fluid escape in subduction zones remain poorly understood. We address this issue by investigating the Erro‐Tobbio meta‐serpentinites (ET‐MS), Italy, exhumed serpentinite rocks that preserve extensive dehydration vein ...
