Insights of Active Extension Within a Collisional Orogen From GNSS (Central Betic Cordillera, S Spain)

Tectonics, Volume 42, Issue 7, July 2023., 2023
Abstract The coexistence of shortening and extensional tectonic regimes is a common feature in orogenic belts. The westernmost end of the Western Mediterranean is an area undergoing shortening related to the 5 mm/yr NNW‒SSE convergence of the Nubia and Eurasia Plates. In this region, the Central Betic Cordillera shows a regional ENE‒WSW extension. Here,

Two‐Way Assessment of Ionospheric Maps Performance Over the Brazilian Region: Global Versus Regional Products

Space Weather, Volume 21, Issue 2, February 2023., 2023
Abstract Vertical total electron content (VTEC) has great importance in describing the ionosphere. VTEC values are commonly distributed in regular grids by means of so‐called global ionospheric maps (GIMs) and regional ionospheric maps (RIMs). Although considerable research has been conducted to develop regional and global models, there is no clear ...

The Role of Faults as Barriers in Confined Seismic Sequences: 2021 Seismicity in the Granada Basin (Betic Cordillera)

Tectonics, Volume 41, Issue 9, September 2022., 2022
Abstract Fault barriers are key structures for studying seismic hazard in regions of intense brittle deformation. The interaction between fault sets affects their seismogenic behavior, if some of them act as barriers. The Granada Basin, in the Betic Cordillera, is a region affected by shallow brittle deformation, as it was the scenario for the recent ...

Thematic quality assessment of land surface geospatial data based on confusion matrices: A matrix set for research on measures and procedures

Geoscience Data Journal, Volume 9, Issue 1, Page 37-45, June 2022., 2022
Entity‐relationship diagram (ERD) of the confusion matrix dataset. Abstract The confusion matrix has long been adopted as the ‘de facto’ and ‘de jure’ standard method of reporting on the thematic accuracy assessment of any land surface geospatial dataset.

3D GNSS Velocity Field Sheds Light on the Deformation Mechanisms in Europe: Effects of the Vertical Crustal Motion on the Distribution of Seismicity

Journal of Geophysical Research: Solid Earth, Volume 127, Issue 6, June 2022., 2022
Abstract Crustal deformation and seismicity in Europe are still poorly understood. Seismic activity is classically ascribed to crustal strain rates generated by edge‐driven tectonic forces. However, crustal deformation is not only due to tectonic loading, but can also be related to isostatic and mantellic processes that induce additional stress and ...

High‐ and Low‐Angle Normal Fault Activity in a Collisional Orogen: The Northeastern Granada Basin (Betic Cordillera)

Tectonics, Volume 40, Issue 7, July 2021., 2021
Abstract Understanding active tectonics and seismicity in extensional settings requires the analysis of high‐angle normal faults (HANFs) and the transfer of deformation at depth. The debate surrounds the role of low‐angle normal faults (LANFs) in triggering high magnitude earthquakes.
