Neotectonic characterization of potential seismogenic structures in NW Argentina

2023
Historical and instrumental seismicity records from the Central Andes of north-western Argentina spanning the last ca. 350 years have been the primary data source to characterize this region’s exposure to seismic hazard as “moderate” to “high” (0.18-0.25 PGA).

Imaging seismogenic structures with local earthquake tomography

Physics and Chemistry of the Earth, 1996
Abstract 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, 1990
Abstract 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.

Seismogenic structures in the central Virginia seismic zone

Geology, 1988
A correlation between earthquake hypocenters and seismic reflection data in central Virginia has become apparent on an automatic line drawing (ALD) display of seismic reflection data. With the reprocessed Virginia I-64 reflection Vibroseis data extended to 14 s, reflectors are imaged from the lower crust as well as from the upper crust.

The structure of an exhumed intraplate seismogenic fault in crystalline basement

Tectonophysics, 2013
Abstract The 600 m-thick Gole Larghe Fault Zone (GLFZ) is hosted in jointed crystalline basement and exposed across glacier-polished outcrops in the Italian Alps. Ancient seismicity is attested by the widespread occurrence of cataclasites associated with pseudotachylytes (solidified frictional melts) formed at 9–11 km depth and ambient temperatures ...

Moho depth, seismicity and seismogenic structure in China mainland

Tectonophysics, 2014
Abstract 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

Structural characterization of potentially seismogenic faults in the Fort Worth Basin

Interpretation, 2020
From 2006 through mid-2018, there have been 125 [Formula: see text] 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-pressure ...

Scale-dependence in Earthquake Processes and Seismogenic Structures

Pure and Applied Geophysics, 2000
We 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 thickness of California: Implications for thermal structure and seismic hazard

Tectonophysics, 2020
Abstract 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 ...
