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

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

open access: yesEarth and Planetary Science Letters, 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.

Ice nucleation under cirrus cloud conditions [PDF]

open access: yes, 2012
Cirrus are thin upper tropospheric clouds that are composed entirely of ice particles. Due to their extensive coverage of the Earth’s surface, they have a significant impact on the Earth’s radiative balance.

Combined approach of poroelastic and earthquake nucleation applied to the reservoir-induced seismic activity in the Val d’Agri area, Italy

open access: yes, 2020
In this work, an approach is developed to study the seismicity associated with the impoundment and level changes of a water reservoir (reservoir induced seismicity – RIS).

Unstable Slip Pulses and Earthquake Nucleation as a Nonequilibrium First-Order Phase Transition. [PDF]

open access: yesPhysical Review Letters, 2018
The onset of rapid slip along initially quiescent frictional interfaces, the process of "earthquake nucleation," and dissipative spatiotemporal slippage dynamics play important roles in a broad range of physical systems.

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).

“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.

Post-earthquake assessment of moderately damaged reinforced concrete plastic hinges

open access: yes, 2020
Modern reinforced concrete buildings are often designed to dissipate energy during strong earthquakes by permitting the controlled formation of plastic hinges. Plastic hinges require assessment of residual capacity in post-earthquake situations. However,

Contribution of Turkish Scholars to Earthquake Literature: The Impact of the Marmara Earthquake [PDF]

open access: yes, 2010
This paper addresses the question of whether the Marmara Earthquake of August 17, 1999, has had an impact on the contribution of Turkish scholars to the earthquake literature.
