Review of geomagnetically induced currents

open access: yes地球与行星物理论评, 2022
Geomagnetic disturbances caused by solar activities induce geoelectric fields on the earth's surface, which generate geomagnetically induced currents (GICs) in electrically conducting systems.

Study on the background characteristics of electric fields constrained by cross-sphere observations

open access: yesEarth, Planets and Space
The interactions among Earth’s spheres constitute both the starting point and ultimate goal of Earth system science research. An in-depth investigation into these interactions is essential for advancing the interdisciplinary integration and collaborative

Deep resistivity imaging across the Northern and Central belts of the Southern Uplands [PDF]

open access: yes, 1995
Magnetotelluric data from 16 soundings have provided a northwest-southeast traverse across the Northern and Central belts of the Southern Uplands. The 34 km profile extends from the Ordovician Portpatrick Formation (northwest of the Thornhill Basin ...

Extended study of extreme geoelectric field event scenarios for geomagnetically induced current applications

open access: yesSpace Weather, 2013
Geomagnetically induced currents (GIC) flowing in man‐made ground technological systems are a direct manifestation of adverse space weather. Today, there is great concern over possible geomagnetically induced current effects on power transmission ...

Modeling Geoelectric Fields in Ireland and the UK for Space Weather Applications [PDF]

open access: yesSpace Weather, 2019
AbstractGeoelectric fields at the Earth's surface caused by geomagnetic storms have the potential to disrupt and damage ground‐based infrastructure such as electrical power distribution networks, pipelines, and railways. Here we model geoelectric fields in Ireland and the UK during both quiet and active time intervals of geomagnetic conditions using ...

On Prediction of Permeability in Sedimentary Rocks Using Geoelectrical Parameters

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Permeability prediction from geoelectrical measurements on sedimentary rocks remains a longstanding challenge due to the complex interplay between pore structure and electrical properties. This study investigates the relationship between permeability and geoelectrical parameters, particularly formation factor (F $F$) and induced polarization ...

Evaluating the applicability of the finite element method for modelling of geoelectric fields [PDF]

open access: yesAnnales Geophysicae, 2013
Geomagnetically induced currents in power systems are due to space weather events which create geomagnetic disturbances accompanied by electric fields at the surface of the Earth.

Space Weather Impact on the Scandinavian Interconnected Power Transmission System [PDF]

open access: yes, 2015
Geomagnetic storms (GMS) can seriously affect high voltage transmission power grids. More specifically, GMS can inject geomagnetically induced currents (GICs) into the power network, thus causing instabilities and eventually leading to grid collapse ...
