Characteristics of surface ruptures produced by recent major earthquakes on the Tibetan Plateau and its surrounding areas, and their tectonic implications

Dizhi lixue xuebao
Objective  Coseismic surface ruptures provide key evidence for identifying the seismogenic structures of earthquakes, elucidating crustal deformation mechanisms, and assessing seismic hazards.

CyberShake NZ: Probabilistic Seismic Hazard Analysis in New Zealand Using Physics‐Based Ground‐Motion Simulations

Earthquake Spectra, Volume 42, Issue 4, November 2026.
This study presents the computational components and workflow developed to conduct probabilistic seismic hazard analysis (PSHA) in New Zealand (NZ) using physics‐based ground‐motion simulations, referred to as “CyberShake NZ.” Semi‐automated procedures generate multiple realizations of kinematic rupture models, create rupture‐specific velocity models ...

Exceptionally Elongated Strike‐Slip Rupture Caused by the 2025 MW 7.8 Myanmar Earthquake

Geophysical Research Letters
The interplay between fault geometry and rupture behavior remains poorly understood. The 2025 Myanmar earthquake ruptured the Sagaing fault, a major continental strike‐slip fault with simple geometry.

Observation of Long Supershear Rupture During the Magnitude 8.1 Kunlunshan Earthquake

, 2003
International audienceThe 2001 Kunlunshan earthquake was an extraordinary event that produced a 400-km-long surface rupture. Regional broadband recordings of this event provide an opportunity to accurately observe the speed at which a fault ruptures ...

Simulation‐Based Nonlinear Site Amplification Models for Western United States

Earthquake Spectra, Volume 42, Issue 4, November 2026.
This article presents one of the first nonlinear (NL) site amplification models relative to VS30 of 800 m/s for the Western United States (WUS) for both the smoothed effective amplitude spectrum (EAS), described as the orientation‐independent horizontal‐component Fourier amplitude spectrum (FAS) of ground acceleration, and the response spectra (RS ...

Revisions to the 2023 U.S. 50‐State National Seismic Hazard Model

Earthquake Spectra, Volume 42, Issue 4, November 2026.
We present an update to the 2023 U.S. 50‐state National Seismic Hazard Model, based on questions and comments received from a range of users, as well as additional internal and building code reviews since its initial release. For the conterminous United States, the update includes (1) revised weighting of ground motion models in the Intermountain West,

Fragility Functions for Plasterboard‐Sheathed Walls in Light Timber‐Framed Residential Houses

Earthquake Spectra, Volume 42, Issue 4, November 2026.
In New Zealand, plasterboard‐sheathed walls (PSWs) are commonly used as partition walls and seismic bracing walls in low‐rise light timber‐framed (LTF) residential houses. A significant barrier to assessing seismic losses of the LTF residential houses in New Zealand is the lack of fragility functions of these PSWs.

Integrating Grain to Ground Motion Data for Critical Rock Bridge and Slope Failure Analysis

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5891-5918, November 2026.
ABSTRACT Rock masses can fail catastrophically with little warning, yet their stability depends on hidden internal connections that channel forces and localise damage. Among these, rock bridges–a “known unknown” in slope mechanics–lock fractured rock and control how failure unfolds, but their concealed geometry and uncertain strength obscure where and ...

Do Shallow Slip Deficits Reflect Fault Structural Maturity or Modeling Choices? A Comparative Analysis of Tibetan Strike‐Slip Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).
