Rheological heterogeneities at the roots of the seismogenic zone [PDF]

Geology, 2023
Abstract Although rheological heterogeneities are invoked to explain differences in fault-slip behavior, case studies where an interdisciplinary approach is adopted to capture their specific roles are still rare. In this work, we integrated geophysical, geological, and laboratory data to explain how rheological heterogeneities influence ...

Fault Stability Across the Seismogenic Zone [PDF]

Journal of Geophysical Research: Solid Earth, 2020
AbstractAcross the seismogenic zone, the transition from brittle to plastic deformation corresponds to a semibrittle regime where brittle fracturing and plastic flow coexist at high strength conditions. Thorough experimental investigations on brittle‐plastic transition are crucial to understand why natural faults behave in stable or unstable ways at ...

Seismogenic zones in Eastern Turkey [PDF]

Geophysical Research Letters, 2003
A 29‐station temporary broadband PASSCAL network was operated from late October 1999 to August 2001 in eastern Turkey in order to decipher the geodynamics of one of the youngest continent‐continent collision zones in the world. This paper focuses on the hypocentral distribution of local earthquakes located during the operation of the network and ...

Thermal squeezing of the seismogenic zone controlled rupture of the volcano-rooted Flores Thrust. [PDF]

Sci Adv, 2021
Temperature plays a critical role in defining the seismogenic zone, the area of the crust where earthquakes most commonly occur; however, thermal controls on fault ruptures are rarely observed directly. We used a rapidly deployed seismic array to monitor

Downdip Variations in Megathrust Seismogenic Behavior in the Japan Trench Subduction Zone Affected by Mantle Wedge Serpentinite

Geophysical Research Letters
It is important to seek geological context for the geophysically observed downdip segmentation of seismogenic behavior of subduction megathrusts. Here we focus on how mantle wedge serpentinite may affect megathrust seismogenesis at Japan Trench—an end ...

Dip angles of active faults from the surface to the seismogenic zone inferred from a 2D numerical analysis of visco-elasto-plastic models: a case study for the Osaka Plain

Earth, Planets and Space, 2021
The geometries (i.e., dip angles) of active faults from the surface to the seismogenic zone are the most important factors used to evaluate earthquake ground motion, which is crucial for seismic hazard assessments in urban areas. In Osaka, a metropolitan

Seismogenic Potential of the Subduction Zone in Northern Chile

Bulletin of the Seismological Society of America, 2023
ABSTRACT The northern Chile region of the Nazca subduction zone ruptured in an Mw∼8.5–9.0 earthquake in 1877, which induced a tsunami. The various magnitude estimates of this event are based on the evaluation of historical records, seismic intensities, and/or tide gauge information; however, its actual along-strike extent is debated ...

GPS probes the kinematics of the Vrancea Seismogenic Zone [PDF]

Eos, Transactions American Geophysical Union, 2004
In late 2001, the Surface Behavior and Dynamical Units of the Southeast Carpathian Tectonics (SUBDUCT) program was initiated by the Netherlands Research Center for Integrated Solid Earth Sciences (ISES), together with the faculty of geology and geophysics at the University of Bucharest, and the (Romanian) National Institute for Earth Physics.The aim of

Paleoearthquakes of the Düzce fault (North Anatolian Fault Zone): Insights for large surface faulting earthquake recurrence [PDF]

, 2008
Copyright 2008 by the American Geophysical Union.The 12 November 1999 Mw 7.1 earthquake ruptured the Düzce segment of the North Anatolian Fault Zone and produced a ∼40-km-long surface rupture.
