The depth extent of the crustal seismogenic zone is closely related to the size of earthquakes. The mechanisms that control the depth of the lower transition of the seismogenic zone are important issues in seismology and disaster mitigation.

Understanding the mechanisms of crustal deformation along convergent margins is critical to identifying seismogenic structures and assessing earthquake hazards for nearby urban centers. In the southern central Andes (28–33 $$^{\circ }$$ ∘ S), differences

Injection‐induced seismicity: Poroelastic and earthquake nucleation effects [PDF]
AbstractThe standard model of injection‐induced seismicity considers changes in Coulomb strength due solely to changes in pore pressure. We consider two additional effects: full poroelastic coupling of stress and pore pressure, and time‐dependent earthquake nucleation.

ABSTRACT This study develops a comprehensive framework for assessing time and state‐dependent aftershock damage accumulation under an M9.0 megathrust interface earthquake in the Cascadia Subduction Zone (CSZ). The framework integrates aftershock probabilistic seismic hazard analysis (APSHA) and state‐dependent fragility analysis (SDFA) within a ...

Study on deformation characteristics and dynamic cause of the Luding MS6.8 earthquake
A MS6.8 earthquake struck Luding Country in Ganzi Prefecture, Sichuan Province on 5 September 2022. The earthquake occurred on the Moxi segment of Xianshuihe fault zone (XFZ), one of the most seismically active faults in the Chinese mainland.

Abstract Quantifying fault frictional properties is fundamental to understanding slip behavior and seismic hazard. We analyze 2 years of Sentinel‐1 SAR data following the 2023 Turkey earthquake doublet using Independent Component Analysis‐enhanced Small Baseline Subset‐InSAR, to resolve postseismic deformation and invert for afterslip on the East ...

Earthquake nucleation on faults with nonconstant normal stress [PDF]
[1] Previous studies have found that earthquake nucleation on faults with rate-and-state dependent constitutive properties is a time dependent process involving evolution of slip rate v and frictional state variable θ. The evolution of θ is governed by an extended aging law, which accounts for the effects of normal stress variations.

Abstract Classical relationships between cumulative and maximum seismic moment, based on the Gutenberg‐Richter law, shows a non‐physical anomaly for low b‐values. We here derive new relationships, including a low and a high b‐value approximation.

Laboratory earthquakes decipher control and stability of rupture speeds
Earthquakes are destructive natural hazards with damage capacity dictated by rupture speeds. Traditional dynamic rupture models predict that earthquake ruptures gradually accelerate to the Rayleigh wave speed with some of them further jumping to stable ...
