Estimation of the Nucleation Location and Rupture Extent of the 1850 Xichang, Sichuan, China, Earthquake by Dynamic Rupture Simulations on a Multi‐Segment Stepover Structure

open access: yesEarth and Space Science, 2023
We simulated the rupture dynamics and ground motion of the 1850 Xichang, China, earthquake on the Zemuhe fault, which consists of the Lijinbao segment, the Dajing segment, the Chechejie segment, and the Songxin segment, with the curved grid finite ...

Triggering mechanism and brittle-ductile dynamics of active faults in the south-central Saurashtra horst, Gujarat, western India: A geospatial, geological, and geophysical approach

open access: yesJournal of Asian Earth Sciences: X, 2023
The seismically active Saurashtra horst is located within the intraplate volcanic continental margin of western India. The region is prone to moderate and low-magnitude earthquakes within the depth range of ∼ 3 to ∼ 24 km.

Largest Aftershock Nucleation Driven by Afterslip During the 2014 Iquique Sequence

open access: yesGeophysical Research Letters, 2023
Various earthquake models predict that aseismic slip modulates the seismic rupture process but actual observations of such seismic‐aseismic interaction are scarce.

Slip weakening, strain and short-termpreseismic disturbances

open access: yesAnnals of Geophysics, 2004
The problem of short-term earthquake precursors is discussed. In contrast to the increasing number of reports on short-lived precursors of various types, direct strain measurements cannot detect clearly expressed preseismic anomalies, as follows from the

Earthquake simulations with time-dependent nucleation and long-range interactions [PDF]

open access: yesNonlinear Processes in Geophysics, 1995
A model for rapid simulation of earthquake sequences is introduced which incorporates long-range elastic interactions among fault elements and time-dependent earthquake nucleation inferred from experimentally derived rate- and state-dependent fault ...

“Bristle-State” Friction: Modeling Slip Initiation and Transient Frictional Evolution From High-Velocity Earthquake Rupture Experiments

open access: yesFrontiers in Earth Science, 2020
Fracture mechanics theory and seismological observations suggest that slip-rate is constantly changing during earthquake rupture, including dramatic acceleration from static conditions to high velocity sliding followed by deceleration and arrest.

The sharp turn: Backward rupture branching during the 2023 Mw 7.8 Kahramanmaraş (Türkiye) earthquake

open access: yesSeismica, 2023
Multiple lines of evidence indicate that the 2023 Mw 7.8 Kahramanmaraş (Türkiye) earthquake started on a splay fault, then branched bilaterally onto the nearby East Anatolian Fault (EAF).

Slip Model of the 2020 Yutian (Northwestern Tibetan Plateau) Earthquake Derived From Joint Inversion of InSAR and Teleseismic Data

open access: yesEarth and Space Science, 2021
Interferometric synthetic aperture radar and teleseismic P‐wave data were combined to investigate the source rupture characteristics of the 2020 Mw 6.3 Yutian, China, earthquake.

Earthquake nucleation in intact or healed rocks [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2015
Abstract Earthquakes are generated because faults lose strength with increasing slip and slip rate. Among the simplest representations of slip‐dependent strength is the linear slip‐weakening model, characterized by a linear drop to a residual friction.
