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 ...

Seismogenic Structure of the 1975 Haicheng Ms 7.3 Earthquake (NE China) Inferred from 3D Magnetotelluric Imaging

Remote Sensing
On 4 February 1975, the Haicheng Ms 7.3 earthquake occurred in the Liaodong Uplift, northeastern China. To investigate its seismogenic structure and deep geological environment, we acquired broadband magnetotelluric data along two intersecting profiles ...

Active faults in the epicentral and mesoseismal Ml 6.0 24, 2016 Amatrice earthquake region, central Italy. Methodological and seismotectonic issues

Annals of Geophysics, 2016
The August 24, 2016 Amatrice earthquake (Ml 6.0) struck a region of the central Apennines (Italy) where several active faults were known since decades, most of which are considered the surface expression of seismogenic sources potentially able to rupture

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,

Evidence for seismogenic fracture of silicic magma

, 2008
It has long been assumed that seismogenic faulting is confined to cool, brittle rocks, with a temperature upper limit of 600 °C (ref. 1). This thinking underpins our understanding of volcanic earthquakes, which are assumed to occur in cold rocks ...

SEISMOGENIC ZONE OF CAPE SHARTLAY (LAKE BAIKAL): SPECIFIC FEATURES OF STRUCTURE, DISPLACEMENTS AND RUPTURE GROWTH

Геодинамика и тектонофизика
Seismogenic deformations of Cape Shartlay represent a very young fault system on the northwestern coast of Lake Baikal. Their study is providing an important opportunity to measure earthquake magnitudes, to identify areas where earthquakes are more ...

SSHAC Revisited: Adapting Site‐Specific Seismic Hazard Analyses for Modern Applications

Earthquake Spectra, Volume 42, Issue 4, November 2026.
During three decades of experience in successfully implementing the SSHAC guidelines for seismic hazard analyses, numerous refinements have been made to the procedures, especially to clarify the process for the lower study levels and simultaneously enhance the relevance of Level 1, 2, and 3 SSHAC studies.

Widespread On‐Fault Geologic Evidence for Variable Mode Coseismic Slip to the Trench in Cascadia

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Investigating the geologic record of near‐trench coseismic strain release is critical for estimating the slip distribution and tsunamigenic potential of future large subduction zone earthquakes. However, the style and extent of upper plate coseismic deformation offshore in subduction zones is poorly constrained.

2017年8月9日精河MS6.6地震余震序列精定位及发震构造分析

Dizhen xuebao, 2019
为确定2017年8月9日精河MS6.6地震的发震构造，本文使用双差定位方法对发震时刻至2017年10月震源区所发生的余震进行了精定位，同时利用CAP波形反演方法，得到了主震的震源机制解，同时使用GPAT方法反演得到了部分余震的震源机制解，并基于两者对本次地震的发震构造予以分析。结果显示：精定位后主震位于（44.27°N，82.85°E），震源深度为17 km；主震最佳双力偶解对应的节面Ⅰ的走向为260°、倾角为51°、滑动角为84°，节面Ⅱ的走向为89.5°、倾角为39.4°、滑动角为97.4 ...
