The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective

Space Weather
The intense May 2024 geomagnetic storm provided an opportunity to conduct the first analysis of geoelectric hazards in Italy. Data from three geomagnetic observatories and a magnetotelluric station were analyzed to examine the spatiotemporal evolution of

Geoelectric Modelling Based on Bessel Functions Integral and Damped Least-Square Inversion for Layered Earth Models [PDF]

Apparent resistivity formulations of a geoelectric method for layered Earth have been obtained analytically in the Bessel functions integral. This formulation is obtained through the application of two boundary conditions.

Localized Threats: How Ground Conductivity Shapes the Geoelectric Response

Space Weather
Geomagnetic storms can induce strong geoelectric fields in the ground. These fields drive geomagnetically induced currents in technological conductor systems, such as power grids.
