Energy and polarization of the telluric field in correlation with seismic activity in Greece
Annals of Geophysics, 2001 Many attempts have been made to disclose anomalous changes of the electromagnetic field in relation with tectonic earthquakes. We tentatively develop a new approach based on the energy and polarity of the electric field, and apply this method to the ...

Analysis of factors affecting the disturbance of geoelectric field observation at Wengtian station
地震科学进展, 2022 The quality of the geoelectric field data of Wenchang Wengtian station in Hainan Province has been declining since March 2019. The quality of the geoelectric field data has declined mainly due to the low daily correlation coefficient, the reverse change ...

Estimating Geomagnetically Induced Currents in Southern Brazil Using 3‐D Earth Resistivity Model
Space Weather, 2023 Geomagnetically induced currents (GICs) result from the interaction of the time variation of ground magnetic field during a geomagnetic disturbance with the Earth's deep electrical resistivity structure.

Study on the change characteristics of regional geoelectric fields
Journal of Earth System Science, 2019 In this study, we illustrate the temporal variations of the geoelectric field and geomagnetic field by data from eight geoelectric field stations and four geomagnetic field stations in Mainland China in 2011. The maximum entropy spectral estimation method (MEM) was used to process the data in our study. The results show that: (i) it is obvious seasonal

Influence of spatial variations of the geoelectric field on geomagnetically induced currents [PDF]
, 2017 The geoelectric field driving geomagnetically induced currents (GIC) has complex spatial variations. It follows that different patterns of the field vectors in a given area having the same regional mean can produce very different GIC.

Benchmarking the Swedish Power Grid Against a 1-in-100-Year Geoelectric Field Scenario [PDF]
Annales GeophysicaeSweden’s communication and power systems have been impacted by major space weather events in the past. For instance, the May 1921 storm caused a fire at the telegraph and telephone station in Karlstad, and the 2003 Halloween storm led to a blackout in ...
