Evaluation of the Caoping electric field observation system in Lixian County, Gansu Province

地震科学进展
In this paper, we briefly conducted an observation overview of the Caoping electric field in Lixian County, collected observation data for graphical analysis, and compared and measured the parameters of observation quality (correlation coefficient and ...

Estimating geoelectric fields for geoelectric hazard assessment: an examination of data and models within complex physiographic zones

, 2019
Includes bibliographical references.2019 Summer.During magnetic storms, time-varying geomagnetic fields induce geoelectric fields at the surface that produce geomagnetically induced currents (GICs) within power transmission systems.

Long term monitoring of the geoelectric field in the UK – 2012–2024 [PDF]

During severe geomagnetic storms, rapid changes in the Earth's magnetic field can induce a significant geoelectric field in the conductive subsurface. This field can cause large potential differences in grounded systems that have long conductors between ...

Why Do Sudden Commencements Sometimes Generate Disproportionate Geomagnetically Induced Currents?

Space Weather
Geomagnetically Induced Currents (GICs) in grounded, conducting infrastructure (e.g., power networks) represent an important space weather hazard. GICs are driven by the changing magnetic field at the Earth's surface.

Geoelectric fields and geomagnetically induced currents during the April 23–24, 2023 geomagnetic storm

Scientific Reports
We 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

Predicting Global Ground Geoelectric Field With Coupled Geospace and Three-Dimensional Geomagnetic Induction Models

Space Weather, 2018
We forecast the global effects of space weather on the geoelectric and geomagnetic fields using a novel combination of methods. We use a realistic three-dimensional (3-D) model of Earth's electrical conductivity and a realistic representation of ...
