Nucleation speed limit on remote fluid-induced earthquakes [PDF]

open access: yesScience Advances, 2017
Larger earthquakes unlocked by fluids are seen globally to take a predictably longer time to begin.

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.

Earthquake nucleation in weak subducted carbonates

open access: yesNature Geoscience, 2016
Ocean-floor carbonate- and clay-rich sediments form major inputs to subduction zones, especially at low-latitude convergent plate margins. Therefore, knowledge of their frictional behaviour is fundamental for understanding plate-boundary earthquakes.

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

“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.

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 ...

New Physical Implications From Revisiting Foreshock Activity in Southern California

open access: yesGeophysical Research Letters, 2023
Foreshock analysis promises new insights into the earthquake nucleation process and could potentially improve earthquake forecasting. Well‐performing clustering models like the Epidemic‐Type Aftershock Sequence (ETAS) model assume that foreshocks and ...
