Comparison of the modelled geoelectric fields of the Carrington and Halloween storms

Journal of Space Weather and Space Climate
An extreme geomagnetic storm comparable to the Carrington event in 1859 could have a significant impact on modern infrastructure, such as power grids. A previously published simulation by Blake et al.

Audiomagnetotelluric sounding using the Schumann resonances [PDF]

, 1987
The Schumann resonance waveforms in the lower ELF band (5-100 Hz) are produced within the Earth-ionosphere cavity by distant lightning discharges; they provide a useful source field for shallow audiomagnetotclluric (AMT) crustal sounding.

Characterizing the distribution of extreme geoelectric field events in Sweden

Journal of Space Weather and Space Climate
Historically, Sweden has reported several impacts on transformers and transmission lines related to geomagnetically induced currents (GICs) that develop during strong space weather events. GICs are driven by the geoelectric field (E), and their intensity depends on various factors, including the lithology conductivity and the rate of change of the ...

The Influence of 3‐D Earth Conductivity, Geoelectric Field Polarization, and Power Grid Topology on GIC Risk

Space Weather
Geomagnetically induced currents (GICs) are naturally occurring electrical currents that flow through the Earth and long conductive infrastructure, such as power lines, during geomagnetic storms.
