Intraplate seismic mechanisms in the Zhangjiakou-Bohai Seismic Belt: insights from magnetotelluric data

Earth, Planets and Space
The Zhangjiakou-Bohai Seismic Belt (ZBSB) is a crucial intraplate seismic belt in Eastern China, covering densely populated and economically developed regions with significant seismic hazards.

Interpretation of the west segment of the coastal fault zone in the coastal region of South China based on the gravity data

Geodesy and Geodynamics, 2018
By systemic processing, comprehensive analysis, and interpretation of gravity data, we confirmed the existence of the west segment of the coastal fault zone (west of Yangjiang to Beibu Bay) in the coastal region of South China.

Genesis of continental seismogenic zone and a new fault zone model

Chinese Science Bulletin, 2000
Experiments were conducted repeatedly on Mannari granite under different temperature and confining pressure conditions. Systematic micro- and submicro-structural and mechanical analyses of granite samples deformed under 1.5 GPa (confining pressure), at 25°C–650°C temperatures and at 2×10−6s−1 strain rate show the brittle-ductile deformation ...

Back‐Propagating Earthquake Rupture Controlled by Fluid‐Modulated Effective Normal Stress

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Back‐propagating earthquake rupture (BPR), where slip migrates opposite to the main rupture direction, is observed in several earthquakes but its origin remains poorly understood, particularly the role of fluids. We use dynamic simulations of frictional sliding coupled with fluids to explore the mechanisms of BPR. Our simulations show that BPR

Fault Geometrical Control on Fault Slip: Experimental Validation of Theoretical Models

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Slip distribution along tectonic faults is recognized as highly heterogeneous across all spatial scales and is linked to various aspects of the earthquake cycle, such as aftershock density and stress‐drop variability. A key factor often considered to control slip heterogeneity is the fault geometry, which is typically nonplanar at various ...

The silent earthquake of 2002 in the Guerrero seismic gap, Mexico (Mw=7.6): Inversion of slip on the plate interface and some implications [PDF]

Geofísica Internacional, 2004
We invert GPS position data to map the slip on the plate interface during an aseismic, slow-slip event, which occurred in 2002 in the Guerrero seismic gap of the Mexican subduction zone, lasted for ~4 months, and was detected by 7 continuous GPS ...

Tectonic Tremor Reveals Slow Deformation Along the Antarctic–South American Subduction Zone

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Antarctic–South American subduction zone is among the least explored convergent margins and lacks documented large interplate earthquakes despite ongoing convergence. Here we report the discovery of tectonic tremor along this plate boundary using continuous seismic data.

InSAR coseismic deformation and seismogenic structure of the 2023 MW6.9 Tajikistan earthquake

Geodesy and Geodynamics
An earthquake of magnitude 6.9 occurred in Tajikistan on February 23, 2023. Studying this earthquake is the key to understanding the seismogenic structure of this area. The slip distribution of the MW6.9 earthquake was inverted using InSAR technology and

Structural control and system-level behavior of the seismic cycle at the Nankai Trough

Earth, Planets and Space, 2020
The Nankai Trough in Southwest Japan exhibits a wide spectrum of fault slip, with long-term and short-term slow-slip events, slow and fast earthquakes, all associated with different segments down the plate interface.

Cascading Rupture of a Conjugate Oblique Faulting Rift in the 2025 Dingri Southern Tibetan Plateau Earthquake: A Typical Slow‐to‐Fast Process

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The 2025 Mw7.1 Dingri earthquake is the largest normal‐faulting event in southern Tibetan plateau recorded with near‐field observations. By integrating back‐projection imaging, multi‐point‐source inversion, and finite‐fault modeling, we reveal that the rupture propagated at variable speeds in a cascading manner across a complex conjugate fault
