The 1980, 1997 and 1998 Azores earthquakes and its seismotectonic implications [PDF]

, 2007
We have studied the focal mechanisms of the 1980, 1997 and 1998 earthquakes in the Azores region from body-wave inversion of digital GDSN (Global Digital Seismograph Network) and broadband data. For the 1980 and 1998 shocks, we have obtained strike– slip

Inversion tectonics of the benue trough

Global Journal of Geological Sciences, 2006
The Benue Trough, an aulacogen at the entrant of the Gulf of Guinea in Nigeria, has been historically studied from the concepts of ortho-mio-eu-geosynclines at outcrops and in the subsurface. Its structural evolution reveals a tectonic scenario compatible with Plate tectonic evolution of the Atlantic Ocean.

The classical Cuevas River section revisited: an update to the style and timing of deformation of the Aconcagua region based on new geological, structural and geochronological data (32°50′S)

Frontiers in Earth Science, 2023
The Aconcagua region constitutes a classical site to study the growth of the Andes, being host of the highest mountain of South America and focus of numerous investigations since its first description by Charles Darwin almost 200 years ago.

Seismological structure of the 1.8 Ga Trans-Hudson Orogen of North America [PDF]

, 2016
Precambrian tectonic processes are debated: what was the nature and scale of orogenic events on the younger, hotter, and more ductile Earth? Northern Hudson Bay records the Paleoproterozoic collision between the Western Churchill and Superior plates—the ∼

Active Inversion Tectonics from Algiers to Sicily [PDF]

, 2019
Using an updated active faults map in the easternmost Western Mediterranean (Algeria to Calabria), plus constraints from geodesy (GPS horizontal motion) and seismology (focal mechanisms) input in a strain model, we discussed how the slow Africa-Eurasia motion (4 mm/year) is accommodated along this segment of the Mediterranean. The width of the inverted

Deciphering the Late Paleozoic–Cenozoic Tectonic History of the Inner Central Andes Forearc: An Update From the Salar de Punta Negra Basin of Northern Chile

Frontiers in Earth Science, 2022
We integrated new and existing geological, geochronological, thermochronological, and two-dimensional (2D) seismic data from the Salar de Punta Negra Basin to define the Late Paleozoic–Cenozoic tectonic evolution of the inner Andean forearc of northern ...

Interpretation of the tectonic evolution of the western part of the Sava Depression: structural analysis of seismic attributes and subsurface structural modeling

Journal of Maps, 2019
This paper presents the results of an extensive structural investigation of the western part of the Sava Depression (SW part of the Pannonian Basin System) and provides insights in the tectonic evolution of the investigated area. Structural analyses were

Constraints on fault and lithosphere rheology from the coseismic slip and postseismic afterslip of the 2006 M_w 7.0 Mozambique earthquake [PDF]

, 2012
The 2006 M_w 7.0 Mozambique (Machaze) normal-faulting earthquake ruptured an unusually steeply dipping fault plane (~75°). The amount of slip in the earthquake decreased from depths of ~10 km toward the surface, and this shallow slip deficit was at least
