Space Weather, Volume 24, Issue 3, March 2026.Abstract Space weather results in risks to gas pipelines in the form of both hazardous levels of pipe‐to‐soil potentials during extreme geomagnetic storms, and accumulated corrosion through less severe, but continuous geomagnetic activity. Here we report on calculations of pipe‐to‐soil potentials during a simulated extreme storm, using both direct ...

Proximity Effects of Lateral Conductivity Variations on Geomagnetically Induced Electric Fields
IEEE Access, 2019 During a magnetic storm, the induced geoelectric field drives geomagnetically induced currents (GIC) in power transmission networks, railway systems, and pipelines, negatively affecting these systems.

April 2000 geomagnetic storm: ionospheric drivers of large geomagnetically induced currents [PDF]
Annales Geophysicae, 2003 Geomagnetically induced currents (GIC) flowing in technological systems on the ground are a direct manifestation of space weather. Due to the proximity of very dynamic ionospheric current systems, GIC are of special interest at high latitudes ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Substorms are often described by a loading‐unloading cycle, where onset follows gradual accumulation of solar wind magnetic flux in the magnetosphere. Yet observations indicate that intense substorms can also be directly driven, though the underlying mechanism remains unresolved.

Influence of spatial variations of the geoelectric field on geomagnetically induced currents
Journal of Space Weather and Space Climate, 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.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract Sudden changes in the ground magnetic field, driven by geomagnetic activity, can ultimately generate geomagnetically induced currents (GICs), which can have a significant impact on artificial technology systems. High rates of change in the horizontal geomagnetic field (dH/dt) can be used as a substitute for the strength of GICs.

Methodology for simulation of geomagnetically induced currents in power systems
Journal of Space Weather and Space Climate, 2014 To assess the geomagnetic hazard to power systems it is useful to be able to simulate the geomagnetically induced currents (GIC) that are produced during major geomagnetic disturbances.

The MANA Magnetometer Array, and Magnetic Observations Across New Zealand From 2024
Space Weather, Volume 24, Issue 2, February 2026.Abstract This paper describes the Magnetometer Array for New Zealand Aotearoa, or MANA, completed in 2023. The network consists of five new variometer sites to complement the existing Eyrewell geomagnetic observatory. Here, we describe the technical details and capabilities of the network, including the hardware and software used. Data products include
