TLDR
In this article, an asymmetric extensional pattern characterized by low-angle, E and NNE-dipping faults, and by antithetic, high-angle and SW-to-WSW-Dipping faults was reconstructed.About:

Probabilistic earthquake relocation in three-dimensional velocity models for the Yellowstone National Park region, Wyoming
TL;DR: In this paper, the locations of 25,267 earthquakes from November 1972 to December 2002 were relocated using three-dimensional velocity models and probabilistic earthquake location, and new coda magnitudes for earthquakes between 1984 and 2002 were computed using an improved coda magnitude equation.

Fault pattern and seismotectonic style of the Campania – Lucania 1980 earthquake (Mw 6.9, Southern Italy): new multidisciplinary constraints
Simone Bello,R. de Nardis,Roberto Scarpa,Francesco Brozzetti,Daniele Cirillo,Federica Ferrarini,B. di Lieto,R. J. Arrowsmith,G. Lavecchia +8 more
TL;DR: In this article, a 3D model of the Campania-Lucania 1980 normal fault outcropping has been built based on the CROP-04 near-vertical seismic profile to reconstruct the surface and depth geometry, kinematics and stress tensor of the seismogenic fault pattern.

Aseismic transient during the 2010-2014 seismic swarm: evidence for longer recurrence of M ≥ 6.5 earthquakes in the Pollino gap (Southern Italy)?
Daniele Cheloni,Nicola D'Agostino,Giulio Selvaggi,Antonio Avallone,Gianfranco Fornaro,R. Giuliani,Diego Reale,Eugenio Sansosti,Pietro Tizzani +8 more
TL;DR: The authors' findings suggest that crustal deformation in the Pollino gap is accommodated by infrequent “large” earthquakes and by aseismic episodes releasing a significant fraction of the accrued strain, and lower strain rates, relative to the adjacent Southern Apennines, and a mixed seismic/aseismic strain release are in favour of a longer recurrence for large magnitude earthquakes in the polls.

Segmentation pattern and structural complexities in seismogenic extensional settings: The North Matese Fault System (Central Italy)
Federica Ferrarini,Paolo Boncio,Rita de Nardis,Gerardo Pappone,Massimo Cesarano,Pietro P. C. Aucelli,Giusy Lavecchia +6 more
TL;DR: In this article, the authors investigated the northern slope of the Matese Mts. (Molise, Central Italy) with the aim of characterizing the N to NE-dipping active normal fault system in the Bojano basin, a sector of primary importance from a seismic hazard perspective.

Scattering and absorption imaging of a highly fractured fluid-filled seismogenetic volume in a region of slow deformation
Ferdinando Napolitano,Luca De Siena,Luca De Siena,Anna Gervasi,Anna Gervasi,Ignazio Guerra,Roberto Scarpa,Mario La Rocca +7 more
TL;DR: In this article, the authors used seismic recordings from the last Pollino swarm (2010-2014) and nearby to separate and map seismic scattering (from P peak-delays) and absorption (from late-time coda-wave attenuation) at different frequencies in the Pollino range and surroundings.

Uniform-sense normal simple shear of the continental lithosphere
TL;DR: In this article, the authors suggest that the thin crust characteristic of the Basin and Range Province extends eastward beneath the west margin of the Colorado Plateau and the Rocky Mountain regions.

The origin of metamorphic core complexes and detachment faults formed during Tertiary continental extension in the northern Colorado River region, U.S.A.
TL;DR: The detachment terranes are relatively young features, formed late in the geological evolution of these bodies, and are only the last in a succession of low-angle normal faults that sliced through the upper crust at the upward terminations of major, shallow-dipping, ductile shear zones in the Cordilleran orogen as mentioned in this paper.
Journal ArticleDOI
Structural evolution of extensional basin margins
TL;DR: In this article, a new model for the structural development of extensional basins is outlined, which suggests a close similarity in geometry between faults in high extension basins such as the North Sea and those in contractional zones.
Journal ArticleDOI
Detachment faulting and the evolution of passive continental margins
TL;DR: In this article, the existence of upper-plate and lower-plate passive margins is investigated and it is shown that detachment models developed for the formation of metamorphic core complexes can also be applied to the forming of passive continental margins, giving rise to a complementary asymmetry of opposing margins after continental breakup.
