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 ...

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 ...

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

Rheological heterogeneities at the roots of the seismogenic zone
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 ...

Progress in Earth and Planetary Science, 2019 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.
