Nowcasting geoelectric fields in Ireland using magnetotelluric transfer functions [PDF]
Journal of Space Weather and Space Climate, 2023 Geomagnetically induced currents (GIC) driven by geoelectric fields pose a hazard to ground-based infrastructure, such as power grids and pipelines. Here, a new method is presented for modelling geoelectric fields in near real time, to provide valuable ...

Mapping Geoelectric Field Hazards in Ireland
Space WeatherGeoelectric fields are generated at the Earth's surface and can lead to the induction of hazardous geomagnetically induced currents (GIC) in infrastructure like power grids, railways and pipelines during geomagnetic storms.

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

Geoelectric monitoring at the Boulder magnetic observatory [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2017 Despite its importance to a range of applied and fundamental studies, and obvious parallels to a robust network of magnetic-field observatories, long-term geoelectric field monitoring is rarely performed.

Geoelectric field response characteristics analysis of floor roadway surrounding rock fracture caused due to coal seam mining [PDF]
Scientific Reports, 2021 The fracture of rocks surrounding the floor roadway during the mining of the working face of a coal mine is a complicated spatiotemporal process due to the superimposed action of multiple stress fields on the surrounding rock mass.

Toward GIC Forecasting: Statistical Downscaling of the Geomagnetic Field to Improve Geoelectric Field Forecasts [PDF]
Space Weather, 2022 AbstractGeomagnetically induced currents (GICs) are an impact of space weather that can occur during periods of enhanced geomagnetic activity. GICs can enter into electrical power grids through earthed conductors, potentially causing network collapse through voltage instability or damaging transformers.

Investigation of the characteristics of geoelectric field signals prior to earthquakes using adaptive STFT techniques [PDF]
Natural Hazards and Earth System Sciences, 2013 An earthquake is one of the most destructive natural disasters that can occur, often killing many people and causing large material losses. Hence, the ability to predict earthquakes may reduce the catastrophic effects caused by this phenomenon.
