Statistics of extreme geomagnetically induced current events

Space Weather, 2008
In this work, space weather events associated with extreme geoelectric field and geomagnetically induced current (GIC) magnitudes are investigated. The geoelectric field and consequent GIC are computed using geomagnetic field recordings over an extended time period and ground conductivity and technological system configurations favorable for large GIC.

Robust Directional Analysis of Magnetic Microscopy Images Using Non‐Linear Inversion and Iterative Euler Deconvolution

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In paleomagnetism, bulk measurements of entire samples have traditionally been used to characterize remanent magnetization. While effective, this approach provides only a general directional estimate and cannot resolve spatial variability or magnetization at the grain scale.

Statistical analysis of geomagnetically induced current data measured around Tokyo, Japan

Earth, Planets and Space
We started measuring geomagnetically induced current (GIC) in substations around Tokyo, Japan in 2017 to study the GIC effects on power systems. We defined a period with GIC continuously exceeding 3 A as a GIC event to analyze the long-term data.

Space Weather Impact on the Scandinavian Interconnected Power Transmission System [PDF]

, 2015
Geomagnetic storms (GMS) can seriously affect high voltage transmission power grids. More specifically, GMS can inject geomagnetically induced currents (GICs) into the power network, thus causing instabilities and eventually leading to grid collapse ...

Northeastern Greenland Paleomagnetic Records Indicate the Influence of Geomagnetic Flux Lobe Intensity on Virtual Geomagnetic Pole Migration During the Holocene

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Paleomagnetic and rock magnetic analyses were conducted on sediment cores from the northeastern Greenland Shelf and Young Sound along the western edge of Fram Strait. The paleomagnetic signal in all three sediment cores is characterized by a strong and stable single component magnetization carried by low coercivity ferrimagnetic single domain ...

Characterisation of grain orientated electrical steels under high DC biased conditions [PDF]

, 2016
Power transformers are designed to operate under pure AC excitation, however they may be subjected to superimposed DC voltages and consequential offset currents, for example from geomagnetically induced currents, GICs, arising from solar activity.

Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

Modeling Study on Energetic Particle Distribution in the Ionospheric South Atlantic Anomaly at Height of the Space Station

Space Weather, Volume 24, Issue 4, April 2026.
Abstract The South Atlantic Anomaly (SAA) in Earth's radiation belt is a critical region that poses significant threats to the safety of Space Stations. This region harbors a high concentration of energetic particles that can penetrate Space Stations, thereby affecting onboard components and posing risks to astronauts.
