Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

Terra Nova, EarlyView.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Quantifying offshore fore-arc deformation and splay-fault slip using drowned Pleistocene shorelines, Arauco Bay, Chile [PDF]

, 2017
Indexación: Web of Science; Scopus.Most of the deformation associated with the seismic cycle in subduction zones occurs offshore and has been therefore difficult to quantify with direct observations at millennial timescales.

Hydro‐Mechanical Controls on Swarm Recurrence on the Westernmost Gofar Transform Fault, East Pacific Rise

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Velocity changes after the 2021 MS 6.4 Yangbi earthquake based on passive image interferometry

Frontiers in Earth Science, 2023
An MS 6.4 earthquake occurred in Yangbi, Yunan Province, China, on 21 May 2021. The epicenter was on the blind branch fault in the west of the Weixi–Qiaohou–Weishan fault, but no surface rupture was obvious.

Evidence for Anthropogenic Surface Loading as Trigger Mechanism of the 2008 Wenchuan Earthquake

, 2011
Two and a half years prior to China's M7.9 Wenchuan earthquake of May 2008, at least 300 million metric tons of water accumulated with additional seasonal water level changes in the Minjiang River Valley at the eastern margin of the Longmen Shan.

Disaggregation of Landslide Risk

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract Quantifying and disaggregating landslide risk through probabilistic landslide risk analysis (PLRA) is critical for land use regulation and risk reduction. However, no transferable model for PLRA currently exists that resolves landslide consequences to individual buildings at regional scales.

Horizontal coseismic deformation of the 1999 Chi-Chi earthquake measured from SPOT satellite images: Implications for the seismic cycle along the western foothills of central Taiwan [PDF]

, 2003
The 1999 Chi-Chi earthquake, M_w = 7.6, broke a major thrust fault along the western foothills of the Central Range of Taiwan. We have measured the horizontal coseismic displacement field by correlating optical satellite images acquired before and after ...

Different Radiation Characteristics Between Foreshocks and Aftershocks of the 2016 Mw7.0 Kumamoto Earthquake in Kyushu, Japan: Implication of Pore Pressure, Stress Concentration, and Loading Rate

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract We estimated the scaled energy (eR ${e}_{R}$) for small earthquakes (1.5≤Mjma≤3.0 $1.5\mathit{\le }{M}_{\text{jma}}\mathit{\le }3.0$) in the focal area of the 2016 Mw 7.0 Kumamoto earthquake to examine the underlying physical processes governing the foreshocks‐mainshock‐aftershock sequence.

Stress buildup in the Himalaya [PDF]

, 2004
The seismic cycle on a major fault involves long periods of elastic strain and stress accumulation, driven by aseismic ductile deformation at depth, ultimately released by sudden fault slip events. Coseismic slip distributions are generally heterogeneous

Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±
