Objective Estimation of Spatially Variable Parameters of Epidemic Type Aftershock Sequence Model: Application to California

, 2017
The ETAS model is widely employed to model the spatio-temporal distribution of earthquakes, generally using spatially invariant parameters. We propose an efficient method for the estimation of spatially varying parameters, using the Expectation ...

Precursory Tidal Triggering of the 2011 Mw 9.0 Tohoku Aftershocks

Applied Sciences, 2022
Precursory earth tidal triggering is believed to influence earthquake timing preferentially when a region is critically stressed. However, whether and how the recurrence of aftershocks after a giant earthquake is affected by tidal triggering remains ...

Post‐earthquake field assessment and damage correlation of elevated reinforced concrete water tanks in Kahramanmaras/Elbistan, Türkiye

Structural Concrete, EarlyView.
Abstract This study evaluates the seismic performance of elevated reinforced concrete (RC) water tanks in the Elbistan region following the February 6, 2023 Kahramanmaras–Elbistan earthquakes. Field investigations, visual damage surveys, non‐destructive testing (ultrasonic pulse velocity—UPV), concrete compressive strength measurements, peak ground ...

Teaching Through Trauma: English Teachers Navigating Affective Regimes in Post‐Earthquake Türkiye

TESOL Quarterly, EarlyView.
Abstract This study explores how English as a Foreign Language (EFL) teachers in post‐earthquake Türkiye narrated their experiences of loss, survival, and teaching within state‐imposed affective regimes. Drawing on an affective–discursive analysis of Ministry of National Education (MoNE) documents and media texts, the study first investigates how ...

Permissible Scale Factors for Various Intensity Measures in Aftershock Ground Motion Scaling

Applied Sciences, 2023
This manuscript investigates the bias introduced by scaling aftershock ground motions when evaluating the performance of structures subjected to earthquake sequences. The study focuses on different hysteretic behaviors exhibited by structures and selects

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Importance of small earthquakes for stress transfers and earthquake triggering

, 2004
We estimate the relative importance of small and large earthquakes for static stress changes and for earthquake triggering, assuming that earthquakes are triggered by static stress changes and that earthquakes are located on a fractal network of ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Orogenic Collapse and Stress Adjustments Revealed by an Intense Seismic Swarm Following the 2015 Gorkha Earthquake in Nepal

Frontiers in Earth Science, 2021
The April 25, 2015 Mw 7.9 Gorkha earthquake in Nepal was characterized by a peak slip of several meters and persisting aftershocks. We report here that, in addition, a dense seismic swarm initiated abruptly in August 2017 at the western edge of the ...
