Geomatics, Natural Hazards & Risk, 2019 The sea-land telluric current vector and its continuity during two geomagnetic storms are discussed using observation data of 13 geoelectric field stations within 100 km of the coastline in China and 5 similar stations in Canada.

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Fugitive methane leakage from legacy oil and gas wells is assessed using surface flux and soil‐gas measurements, yet these signals are modulated by meteorology and shallow processes, obscuring sustained leakage. Whether persistent leakage leaves a coherent imprint in the shallow subsurface remains unresolved. Here we present a multi‐year field

Engineering Reports, Volume 8, Issue 5, May 2026.Integrated VES, ERI, and MASW surveys, constrained by boreholes, delineate a central low‐resistivity/low‐V s weak corridor and more competent volcanic strata at depth. The eastern sector offers preferable foundation conditions, while identified weak zones require ground improvement or deep foundations to mitigate differential‐settlement risk.

Concurrent Oxidative and Reductive Protometabolic Reactions Driven by Electrochemistry
ChemSystemsChem, Volume 8, Issue 3, May 2026.Electrochemistry offers a possible solution to a key question in prebiotic chemistry: how oxidative and reductive reactions could occur simultaneously as they do in modern biochemistry. This study shows that essential redox reactions from the reverse tricarboxylic acid (rTCA) cycle and nucleotide synthesis can be driven concurrently by electrochemistry,

Long term monitoring of the geoelectric field in the UK – 2012–2024 [PDF]
During severe geomagnetic storms, rapid changes in the Earth's magnetic field can induce a significant geoelectric field in the conductive subsurface. This field can cause large potential differences in grounded systems that have long conductors between ...

Range finding of Alfvén oscillations and direction finding of ion-cyclotron waves by using the ground-based ULF finder [PDF]
, 1996 International audienceA new approach to the problem of direction and distance finding of magnetospheric ULF oscillations is described. It is based on additional information about the structure of geoelectromagnetic field at the Earth's surface which is ...

Study on the background characteristics of electric fields constrained by cross-sphere observations
Earth, Planets and SpaceThe interactions among Earth’s spheres constitute both the starting point and ultimate goal of Earth system science research. An in-depth investigation into these interactions is essential for advancing the interdisciplinary integration and collaborative

Regression‐based forecast model of induced geoelectric field
Space Weather, 2017 AbstractThe electric field induced due to solar activity is the driver of geomagnetically induced currents (GIC) in grounded conductor networks such as power grids. We present a regression‐based (i.e., empirical) model for quantitatively predicting the upper envelope of induced E field components, using near‐Earth measurements of solar wind plasma and ...
