Nuclear Magnetohydrodynamic EMP, Solar Storms, and Substorms
, 2003 In addition to a fast electromagnetic pulse (EMP), a high altitude nuclear burst produces a relatively slow magnetohydrodynarnic EMP (MHD EMP), whose effects are like those from solar storm geomagnetically induced currents (SS GIC).

Drastic time variations of transfer function of geomagnetically induced current (GIC) in Japan
, 2022 Abstract Geomagnetically induced currents (GICs) flow in power grid in response to geomagnetic field variations. Because of the potential threat of power outage, GIC is regarded as one of the important aspects of space weather. We calculated the transfer function in frequency domain that describes a linear relationship between the GICs measured

A Mitigation Method Based on the Principle of GIC-Even Distribution in Whole Power Grids
IEEE Access, 2020 The geomagnetically induced currents (GIC) caused by geomagnetic storms can inflict the anomalous operation of power systems, damaging electrical equipment, or even resulting in a large-area blackout of power systems.

Long Period Magnetotellurics (MT) using Geomagnetically Induced Currents in the Scottish Power Network [PDF]
, 2007 Geomagnetically Induced Currents (GIC) which flow in technological systems such as power transmission grids, are a consequence of the geoelectric field induced at the surface of the Earth during geomagnetic storms. We use an electrical model of the power

Space Weather, Volume 24, Issue 2, February 2026.Abstract Auroral substorms are a key manifestation of solar‐terrestrial interactions and the release of energy within the Earth's magnetosphere. The expansion phase, which is characterized by rapid changes in auroral morphology and intensity, poses significant space weather risks to satellite operations and communication systems.

The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective
Space Weather, Volume 24, Issue 1, January 2026.Abstract 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 storm‐induced variations.
