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

open access: yesEarthquake 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 ...

Quantifying the Role of 3D Fault Geometry Complexities on Slow and Fast Earthquakes

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Traditional models of slow slip events (SSEs) oversimplify fault geometry, although imaging shows subduction faults are segmented and complex. We examine how fault interactions control slip behavior using 3D quasi‐dynamic simulations of two parallel faults with uniform rate‐weakening friction accelerated by hierarchical matrices.

Fault Slip Reversals Preceded the Intraplate 2021 Earthquake Series in the Vienna Basin (Central Europe)

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Fault‐slip reversals indicate transient stress changes and may illuminate earthquake preparation processes. Here we present high‐resolution observations of sub‐millimetric creep and slip reversals on the Altaquelle Fault, a Quaternary normal fault in the southern Vienna Basin, preceding a regionally significant intraplate earthquake sequence ...

Segmented Moho Uplift and Implications for Magmatic Underplating Beneath the Datong Basin

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Understanding how the deep crust responds to coupled tectonic and magmatic processes is essential for deciphering intracontinental rifting. We apply high‐resolution passive‐source reverse time migration to teleseismic P‐wave receiver functions recorded by a dense seismic array to image the Moho beneath the Datong Basin. Our observations reveal

The Role of Tectonic Inheritance in Active Rift Seismicity and Magmatism: Constraints From 3‐D Gravity Inversion and D‐InSAR Modeling of the 2025 Fentale Swarm, Ethiopia

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The role of inherited lithospheric structures in active rift seismicity and magma intrusion remains a key uncertainty in continental breakup dynamics. We investigate the January 2025 Northern Main Ethiopian Rift swarm using constrained 3‐D gravity inversion and D‐InSAR observations to characterize crustal architecture, seismicity, and active ...

Aseismic Slip Along the Evaporite‐Rich Strike‐Slip Katouna‐Stamna Fault in Greece

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Aseismic slip has been observed on many active faults globally, but its controlling mechanisms remain unclear. This study focuses on the NW‐striking, left‐lateral Katouna‐Stamna Fault in Western Greece. We use InSAR surface deformation measurements to confirm the presence of aseismic slip and compare this behavior with structural evidence from

Plume‐Fed Magmatic Fluids Weakened Crust and Promoted a Large Intraplate Earthquake in Northern Hainan (South China)

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Large intraplate earthquakes are paradoxical because they occur far from active plate boundaries. Northern Hainan Island (South China) hosts the 1605 Qiongbei M7.5 earthquake within a volcanic province linked to the Hainan mantle plume. New shear‐wave velocity images reveal two shallow low‐velocity zones extending to ∼10 km depth: a stronger ...

3D Subduction Interface Model for the Hikurangi Margin, New Zealand: Implications for Slow Slip Events

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions in slow slip events (SSEs) that correlate with subduction interface ...

Sumatra Seismogenic Zone - The role of input materials in shallow seismogenic slip and forearc plateau development [PDF]

open access: yes, 2017
Drilling the input materials of the north Sumatran subduction zone, part of the 5000 km long Sunda subduction zone system and the origin of the Mw ~9.2 earthquake and tsunami that devastated coastal communities around the Indian Ocean in 2004, was ...

Predicting Seismic Intensity Using Machine Learning With Ancillary Data: Evidence From Destructive Earthquakes in China

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
A machine learning framework integrating multisource seismic, social, and geographic data accurately predicts kilometer‐scale seismic intensity, enabling rapid postearthquake damage assessment during data‐scarce “black‐box” periods. ABSTRACT Accurate and rapid assessment of seismic intensity is crucial for postearthquake emergency response.
