Silica precipitation potentially controls earthquake recurrence in seismogenic zones. [PDF]

Sci Rep, 2017
AbstractSilica precipitation is assumed to play a significant role in post-earthquake recovery of the mechanical and hydrological properties of seismogenic zones. However, the relationship between the widespread quartz veins around seismogenic zones and earthquake recurrence is poorly understood.

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 ...

Very Low Frequency Earthquakes in Between the Seismogenic and Tremor Zones in Cascadia?

AGU Advances, 2022
Megathrust earthquakes and their associated tsunamis cause some of the worst natural disasters. In addition to earthquakes, a wide range of slip behaviors are present at subduction zones, including slow earthquakes that span multiple orders of spatial ...

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

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 ...

Features of the potential seismogenic zone of the Ingul and Srednepridneprovsky megablocks of the Ukrainian Shield

Геофизический журнал, 2013
Special features of seismogenic zone of the Ingul and MiddleDnieper megablocks of the Ukrainian Shield have been analyzed. Several seismogenic zones with small areas have been subdivided within its limits, which differ by degree of contrast of ...

Geological constraints on dynamic changes of fluid pressure in seismic cycles

Scientific Reports, 2022
Fluid pressure along faults plays a significant role in fault behaviors in seismic cycles in subduction zones. When a thermal pressurization event occurs, the fluid pressure rises; conversely, when a fault-valve behavior event occurs, the fluid pressure ...
