Data‐Driven Transfer Functions From Differential Magnetometer Measurements to Enhance GIC Model Validation Capability: A Case Study in the Spanish Power Grid Open
Geomagnetically induced currents (GICs) are unwanted currents flowing in long grounded conductors because of space weather phenomena. Example GICs are those flowing in power transmission lines via grounded transformer neutrals. Prediction …

Estimation of the high amplitudes of the geoelectric field Open
The geoelectric field depends on the electrical structure of the ground and the time variations of the geomagnetic field, which become more intense during geomagnetic storms. We present a procedure for identifying the areas of higher ampli…

Volcanic monitoring of the 2021 La Palma eruption using long-period magnetotelluric data Open
Between September and December 2021, the first subaerial volcanic eruption in the Canary Islands in 50 years took place on the island of La Palma. Since November 2021, we have been conducting a long-period magnetotelluric (MT) monitoring e…

High-resolution scan of the Pyrenean crustal structure combining magnetotelluric and gravity data Open
The Pyrenees have undergone complex geodynamic evolution starting with experiencing significant tectonic events during the Variscan Orogeny, followed by the intrusion of large granitic complexes during the late Variscan stage, then the col…

Expected Geomagnetically Induced Currents in the Spanish Islands Power Transmission Grids Open
The aim of this study is to evaluate the geomagnetically induced current (GIC) hazard in the power networks of the Canary and Balearic archipelagos. This is done in order to strictly complete the detailed assessment at national level of th…

Els Casots (Subirats, Catalonia), a key site for the Miocene vertebrate record of Southwestern Europe Open
Els Casots is one of the richest fossil vertebrate sites of the Vallès-Penedès Basin (Catalonia, Spain). It was discovered in 1989 and excavated briefly during the 1990s, resulting in the recovery of thousands of remains and the erection o…

New Detailed Modeling of GICs in the Spanish Power Transmission Grid Open
The threat of Geomagnetically Induced Currents (GICs) driven by severe Space Weather looms over technological systems such as power grids. Assessing their vulnerability is thus vital to avoid damages or even disruption of the electrical po…

Integrated seismic ambient noise, magnetotellurics and gravity data for the 2D interpretation of the Vallès basin structure in the geothermal system of La Garriga-Samalús (NE Spain) Open
The integration of geophysical methods, together with the previous information of the Vallès basin area, has resulted in the creation of a new conceptual model that explains La Garriga-Samalús geothermal system. The integration of compleme…

Integration of geophysical methods and fractures study for the Vallès geothermal system characterization (NE Spain) Open
<p>The Vall&#232;s geothermal system is located in the Catalan Coastal Ranges (CCR) (NE Spain). The CCR are formed by horst and graben structures limited by NE-SW and ENE-WSW striking normal faults, developed during the opening o…

Magnetotelluric Characterization of the Alhamade Murcia Fault (Eastern Betics) - PreliminaryResults Open
The Lorca Earthquake (11/5/2011, Mw 5.2) stands as the most destructive in Spain over the last 50 years. It was interpreted as having occurred in an intersegment zone of the strike-slip Alhama de Murcia Fault (AMF). Within the research pro…
