Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Unraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic afterslip associated with the 2025 Mw 8.8 Kamchatka earthquake.

Evidence for postseismic deformation of the lower crust following the 2004 Mw6.0 Parkfield earthquake [PDF]
, 2011 Previous studies have shown that postseismic relaxation following the 2004 Mw6.0 Parkfield, CA, earthquake is dominated by afterslip. However, we show that some fraction of the afterslip inferred from kinematic inversion to have occurred immediately ...

Earthquake ScienceThe 2015 Gorkha (MW=7.8) earthquake ruptured the downdip portion of the Main Himalayan Thrust. Afterslip following this event provides valuable insights into the frictional properties on the thrust interface, yet its amplitude and distribution remain ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.

Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...

2001年MW7.8昆仑山地震震后形变观测、机制与青藏高原中北部岩石圈流变：认识与挑战
Dizhen xuebao, 2021 2001年MW7.8昆仑山地震是近半个世纪以来青藏高原发生的最大震级地震。同震破裂产生的巨大应力扰动驱动控制着显著震后形变。二十年尺度的大地测量数据记录了地震后长时间、大范围、时空依赖的震后形变演化过程及差异，揭示了昆仑山地震破裂段复杂的断层分段震后运动学特征、分段摩擦性质差异和青藏高原中北部岩石圈流变性质/结构横向各向异性。本文简要回顾昆仑山地震后基于二十年尺度时序InSAR和GPS的震后形变观测方法和时空特征，特别是时空密集的InSAR观测，是该构造区震后GPS观测的重要补充及其不可替代的观测手段 ...

Partial Ruptures, Cascading Multi‐Fault Ruptures, and Aftershocks in 2D Random Fault Network
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The Gutenberg‐Richter law for the distribution of earthquake magnitude and the Omori law for the decay of aftershocks are two universal laws in seismicity. Although numerical models have been developed to reproduce these laws, they sometimes produce many more foreshocks and fewer aftershocks than observed.

Geophysical Research Letters, 2012 Prior to the 2011 M9 Tohoku‐oki earthquake, subduction at the Japan Trench was characterized by M7‐8 earthquakes, sometimes rupturing the same source regions (seismic asperities), followed by extensive afterslip detected by GPS measurements. A physically‐

Shallow Creep in the Leaky Stress Shadow of Locked Zones of Subduction Megathrust
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract In some subduction zones such as Nankai, creeping of the shallow part of the megathrust in the stress shadow of deeper locked zones is detected by seafloor geodetic measurements and/or reflected by slow earthquakes (SEQs). Here we explain that shallow creep occurs in the stress shadow for two reasons: (a) prolonged afterslip and (b) a leaky ...
