Dynamics of a fault model with two mechanically different regions
Earth, Planets and Space, 2017 We consider a fault containing two regions with different mechanical behaviours: a strong, velocity-weakening region (asperity) and a weak, velocity-strengthening region.

Coseismic and postseismic fault slip characteristics of the 2020 MW6.3 Nima earthquake
地球与行星物理论评, 2023 The 2020 MW6.3 Nima earthquake occurred in the northern Yibug Caka graben on the Qiangtang Block of the Tibetan Plateau. The epicentral area has complex geological structures, topography, and geomorphology, and there are few near-field ground observation

A viscoelastic and afterslip postseismic deformation model for the 1964 Alaska earthquake [PDF]
Journal of Geophysical Research: Solid Earth, 2009 We developed a 3‐D viscoelastic model, in concert with an afterslip model, to describe the postseismic deformation following the 1964 Alaska earthquake. Our model incorporates a realistic geometry including an elastic slab with very low dip angle. These geometric factors are important and require a reanalysis of the 1964 coseismic model.

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract On 9 November 2025, a Mw 6.8 Sanriku‐Oki earthquake struck a Japan Trench segment with inferred recurrent aseismic slip and Mw ∼7 earthquakes. Using S‐net seafloor data, we examine the preparatory and post‐mainshock evolution of this foreshock–mainshock–aftershock sequence.

Rapid afterslip following the 1999 Chi‐Chi, Taiwan Earthquake [PDF]
Geophysical Research Letters, 2002 Postseismic displacements of as much as 14 cm were recorded by GPS measurements in the 3 months following the MW 7.6 1999 Chi‐Chi, Taiwan earthquake. Data from 35 continuous and 90 campaign‐surveyed stations, which show continued east over west thrusting, are analyzed to estimate the postseismic slip distribution and fault geometry.

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 ...

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.The evolution of pore fluid pressure ( Pf$P_{\mathrm{f}}$) in the most seaward portion of a subduction accretionary prism plays an essential role in the cycle of tsunamigenic earthquakes. Based on recent geophysical observations, here we propose a testable conceptual model for this evolution for northern Cascadia offshore of Washington.

Strain waves, earthquakes, slow earthquakes, and afterslip in the framework of the Frenkel-Kontorova model [PDF]
Physical Review E, 2009 The one-dimensional Frenkel-Kontorova (FK) model, well known from the theory of dislocations in crystal materials, is applied to the simulation of the process of nonelastic stress propagation along transform faults. Dynamic parameters of plate boundary earthquakes as well as slow earthquakes and afterslip are quantitatively described, including ...

AGU Advances, Volume 7, Issue 3, June 2026.Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).

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 ...
