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.

Earthquakes of the Nepal Himalaya : Towards a Physical Model of the Seismic Cycle [PDF]

open access: yes, 2013
Home to hundreds of millions of souls and land of excessiveness, the Himalaya is also the locus of a unique seismicity whose scope and peculiarities still remain to this day somewhat mysterious.

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

How do earthquakes start? A seismological investigation into earthquake nucleation and determinism

open access: yes
Scientists continue to debate many questions about the beginnings of earthquakes. At the single event scale, what processes go on in the earliest stages of rupture, and do they depend on magnitude? At a large scale, what processes cause earthquakes to occur when they do, and can foreshocks give insights into earthquake nucleation?

“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.

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.

Observation of a Synchronicity between Shallow and Deep Seismic Activities during the Foreshock Crisis Preceding the Iquique Megathrust Earthquake

open access: yesSeismica, 2023
We analyze at a broad spatial scale the slab seismicity during one of the longest and best recorded foreshock sequence of a subduction earthquake to date: the M8.1 2014 Iquique earthquake in Chile.

Modelling fluid flow in complex natural fault zones: Implications for natural and human-induced earthquake nucleation [PDF]

open access: yes, 2020
Pore fluid overpressures in active fault systems can drive fluid flow and cause fault weakening and seismicity. In return, deformation accommodated by different modes of failure (e.g. brittle vs.
