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 ...

Thermal models of the Mexico subduction zone: Implications for the megathrust seismogenic zone [PDF]
Journal of Geophysical Research: Solid Earth, 2002 It has been proposed that the seismogenic zone of subduction thrust faults is primarily controlled by temperature or rock composition changes. We have developed numerical models of the thermal structure of the Mexico subduction zone to examine the factors that affect the temperature of the subduction thrust fault. Although the oceanic plates subducting

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 ...

Geochemistry, Geophysics, Geosystems, 2021 Whether tectonic convergence at subduction zones is accommodated predominantly through seismic or aseismic deformation, the former potentially generating large earthquakes, varies considerably between subduction margins. This margin‐scale variability has

Microscale cavitation as a mechanism for nucleating earthquakes at the base of the seismogenic zone [PDF]
Nature Communications, 2017 AbstractMajor earthquakes frequently nucleate near the base of the seismogenic zone, close to the brittle-ductile transition. Fault zone rupture at greater depths is inhibited by ductile flow of rock. However, the microphysical mechanisms responsible for the transition from ductile flow to seismogenic brittle/frictional behaviour at shallower depths ...

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.

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

Earthquake and Tsunami NaTech Risk Assessment for Oil Storage Facilities
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1887-1904, 25 July 2026.ABSTRACT Interaction of natural and technological hazards (NaTech) events, such as tsunamis and earthquakes, can affect industrial facilities such as those featuring anchored atmospheric storage tanks. Consequences of natural events on this kind of installation may include the release of hazardous substances, which in turn can lead to industrial ...
