GIC‐Related Observations During the May 2024 Geomagnetic Storm in the United States

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The May 2024 geomagnetic storm was one of the most severe in the past 20 years. Understanding how large geomagnetic disturbances (GMDs) impact geomagnetically induced currents (GICs) within electrical power grid networks is key to ensuring their resilience.

A review of studies combining natural-source electromagnetic soundings and petrophysical experiments to constrain the volatile distribution in the deep earth

地球与行星物理论评
Volatiles (such as H2O, CO2) are the crucial factors controlling the physical-chemical properties and dynamic processes of the multi-layer system within the Earth, and therein play an important role in plate tectonics, magmatic-mineral activities, and ...

Leveraging Legacy Broadband Magnetotelluric Data for Geoelectric Field Hazard Assessment in Southern Italy

Space Weather, Volume 24, Issue 5, May 2026.
Abstract Geomagnetically induced currents (GICs) are a significant space weather hazard. Their accurate assessment requires estimating the geoelectric field, which depends on the Earth's subsurface electrical conductivity. While long‐period magnetotelluric (MT) surveys are ideal, archives of legacy broadband MT data, originally acquired for geological ...

Identification and parameter estimation for electrical anisotropy in two-dimensional magnetotelluric models

Frontiers in Earth Science
When the subsurface media contain electrical anisotropic structure, magnetotelluric isotropic inversion fails to recover the electrical anisotropic structure and may distort the image of isotropic structures. Besides, due to the diversity and uncertainty

Magnetotelluric Exploration of Zn Pb Mineralization in Stonepark, Irish Midlands

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT To meet the increasing demand for raw materials and to foster the energy transition, advances in exploration techniques are required that extend capabilities to deeper and/or more densely populated areas while having a low environmental and societal impact.

Long‐Term Stability, Noise, and Temperature Sensitivity of Modular Porous‐Pot Electrodes Designed for Geophysical and Geotechnical Applications, and Details of Their Construction

Earth and Space Science
Electrodes are used to measure a potential difference between two points. In geophysical and geotechnical applications they are often in the form of non‐polarizable porous‐pot electrodes.

Magma and Volatile Pathways Beneath Sakurajima Volcano From Self‐Potential, Helium Isotopes, and Broadband Magnetotellurics

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract At frequently erupting volcanoes, magma and volatiles ascend through established pathways, but the complete picture of their branching and supply system remains unclear. We integrated self‐potential (SP), broadband magnetotelluric (MT), and helium isotope observations to image magma and volatile pathways beneath Sakurajima Volcano.
