Katz Fractal Dimension of Geoelectric Field during Severe Geomagnetic Storms [PDF]

open access: yesEntropy, 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]

open access: yesScientific 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.

Mapping Geoelectric Field Hazards in Ireland

open access: yesSpace Weather
Geoelectric 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.

Estimating the Geoelectric Field and Electric Power Transmission Line Voltage During a Geomagnetic Storm in Alberta, Canada Using Measured Magnetotelluric Impedance Data: The Influence of Three‐Dimensional Electrical Structures in the Lithosphere

open access: yesSpace Weather, 2021
Estimating the effect of geomagnetic disturbances on power grid infrastructure is an important problem since they can induce damaging currents in electric power transmission lines. In this study, an array of magnetotelluric (MT) impedance measurements in

Features and Source Current of Long‐Period Induced Geoelectric Field During Magnetic Storms: A Case Study

open access: yesSpace Weather, 2020
We present a case study on the long‐period ( >105 s) induced geoelectric field disturbance during magnetic storms. A set of continuous 33‐day measurements of the geoelectric field, geomagnetic field, geomagnetic indices, and interplanetary magnetic field

Nowcasting geoelectric fields in Ireland using magnetotelluric transfer functions

open access: yesJournal 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 ...

Study in Natural Time of Geoelectric Field and Seismicity Changes Preceding the Mw6.8 Earthquake on 25 October 2018 in Greece. [PDF]

open access: yesEntropy (Basel), 2018
A strong earthquake of magnitude Mw6.8 struck Western Greece on 25 October 2018 with an epicenter at 37.515∘ N 20.564∘ E. It was preceded by an anomalous geolectric signal that was recorded on 2 October 2018 at a measuring station 70 km away from the ...
