Coseismic deformation and seismogenic structure of the 2024 Hualien Earthquake measured by InSAR and GNSS

Earthquake Research Advances
On April 3, 2024, an M7.3 earthquake occurred in the offshore area of Hualien County, Taiwan, China. The seismogenic structure at the epicentral location was highly complex, and studying this earthquake is paramount for understanding regional fault ...

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 ...

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.

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).

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.

Structural characterization of potentially seismogenic faults in the Fort Worth Basin

Interpretation, 2020
Abstract 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 ...

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 Ancient Structures of the Center and North of the East European Platform

Doklady Earth Sciences, 2019
The 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 ...
