Imaging seismogenic structures with local earthquake tomography
Physics and Chemistry of the Earth, 1996Abstract Detailed tomographic images of the upper crust along and across active faults reveal the presence of fault heterogeneities — mainly due to lithologic discontinuities — defining areas with markedly different dynamic behavior during the rupture of large events (M ∼7), and interpreted as discrete fault segments.

Structural and fluid-chemical properties of seismogenic normal faults
Tectonophysics, 1990Abstract Structures in extensional fault zones can be classified using the configuration of fault branch lines and tip lines. Important classes include the segment bend, segment termination, segment branch, cross-fault intersection, and segment offset.

Structural characterization of potentially seismogenic faults in the Fort Worth Basin
Interpretation, 2020Abstract From 2006 through mid-2018, there have been 125 Mw≥2.5 recorded earthquakes within the Fort Worth Basin and the Dallas-Fort Worth metropolitan area. There is general scientific consensus that this increase in seismicity has been induced by increases in pore-fluid pressure from wastewater injection and from cross-fault pore ...

Seismogenic structures of the collision-subduction zone in the eastern Taiwan
2020<p>The Taiwan orogenic belt is relatively young and active with an ongoing arc-continent collision since the middle Miocene. In this study, we systematically investigate the use of seismic tomography, focal-mechanism and distribution of earthquakes to analysis the seismogenic patterns in the collision-subduction zone in the ...

Seismogenic Thickness of California: Implications for Thermal Structure and Seismic Hazard
Tectonophysics, 2020Abstract The seismogenic thickness of the crust, a proxy for brittle-crust thickness, is a geometric parameter related to crustal strength, seismic hazard, and the crust's thermo-mechanical nature. We use high-resolution earthquake-location data from California to construct a topographic map of the base of the seismogenic crust by calculating the ...

Moho depth, seismicity and seismogenic structure in China mainland
Tectonophysics, 2014Abstract The study of the crust–upper mantle structure based on wide-angle seismic profiles performed in China mainland since 1958, has provided tighter constraints on the architecture and deformation of the lithosphere; but the link between the seismic velocity structure and the seismogenic layer of the crust is still an open problem in which we are

Scale-dependence in Earthquake Processes and Seismogenic Structures
Pure and Applied Geophysics, 2000We provide a positive answer to the question whether large earthquakes can be separated from small ones using various observations on the earthquake processes and seismogenic structures. For California, the boundary of separation is at M = 5. This conclusion leads to the possibility of deterministic modeling of earthquake occurrence for prediction.

Seismogenic Ancient Structures of the Center and North of the East European Platform
Doklady Earth Sciences, 2019The location of earthquake epicenters in the central and northern parts of the East European Platform in 2009–2016 has been analyzed. The earthquake epicenters have been recorded by seismic stations of the Geophysical Survey of the Russian Academy of Sciences and using the Mikhnevo Small-Aperture Array of the Institute of Geosphere Dynamics, Russian ...

GEOELECTRICAL CHARACTERISTICS OF SEISMOGENIC STRUCTURE IN THE BAIKAL PREDICTION TESTING GROUND
Russian Geology and Geophysics, 1993Geoelectrical characteristics of the upper crust of the southern section in the Baikal prediction testing ground, including the northeastern wing of the Selenga depression, from village of Kudara to village of Kluchi-Stvolovaya on the northeast are given in the paper.

Seismic Instruments, 2017
Extended horizons of 0.5–2-m-thick soft-sediment deformation structures, which were earlier described as the effects of strong earthquakes in the Late Pleistocene, are studied in glaciolacustrine deposits of the Khibiny massif (central part of the Kola Peninsula).
