Detailed shallow structure of the seismogenic fault of the 1976 Ms7.8 Tangshan earthquake, China
Frontiers in Earth Science, 2022 In 1976, an Ms7.8 strong earthquake occurred in the Tangshan region of Northeast China within an ancient craton. In this study, we conducted shallow seismic exploration, drilling-based exploration, and exploratory trench excavation of ground fissures in ...

Seismogenic Structures in Subduction Zones
Surveys in GeophysicsAbstract Recent studies of high-resolution seismic tomography of source zones of large crustal earthquakes, megathrust earthquakes, and intraslab earthquakes are reviewed, which shed new light on seismogenic structures and fluids in subduction zones.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment
Terra Nova, EarlyView.ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

Potential Bias in Inferred Megathrust Slip Rates Induced by the Neglect of Material Heterogeneity
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Accurate knowledge of the pattern of interseismic coupling on megathrusts is critical to preparing for future earthquakes and tsunamis. However, published models for a given fault zone commonly differ widely, making hazard assessment difficult.

The 2013 Slab‐Wide Kamchatka Earthquake Sequence
Geophysical Research Letters, 2023 Studies of initiation of large earthquakes are usually focused on frictional instabilities occurring in the near vicinity of the future rupture. Possible contributions of long‐distance interactions with large‐scale tectonic instabilities remain unknown ...
