Katz Fractal Dimension of Geoelectric Field during Severe Geomagnetic Storms [PDF]
Entropy, 2021 We are concerned with the time series resulting from the computed local horizontal geoelectric field, obtained with the aid of a 1-D layered Earth model based on local geomagnetic field measurements, for the full solar magnetic cycle of 1996–2019 ...

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.

Nowcasting geoelectric fields in Ireland using magnetotelluric transfer functions
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.

Influence of geoelectric field on chemical reactions on Earth [PDF]
Доповiдi Нацiональної академiї наук УкраїниThe existing understanding of chemical thermodynamics presupposes that at the same temperature and other conditions being equal, the rate of a chemical reaction will always and everywhere on Earth be constant.

Independent component analysis of geoelectric field data in the northern Nagano, Japan. [PDF]
Proc Jpn Acad Ser B Phys Biol Sci, 2009 Simultaneous anomalous change of geoelectric field was observed on January 17, 1999 at three far-distant stations in Nagano Prefecture, Japan. Eleven days after the anomalous change, an earthquake swarm with a M4.8 main shock started at a location within the triangle formed by the three stations.

Geoelectric fields and geomagnetically induced currents during the April 23–24, 2023 geomagnetic storm [PDF]
Scientific ReportsWe present a study on the dynamical variations of geoelectric fields E during the intense geomagnetic storm of April 23–24, 2023. The storm is caused by the interplanetary counterpart of a coronal mass ejection erupted from the Sun in association with an
