Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Magnetotelluric (MT) survey results from the Late Archean Manica greenstone belt, an extension of the Odzi‐Mutare greenstone belt of the Zimbabwe Craton, are presented. A total of 33 MT stations were acquired on an irregular grid with an average station spacing of approximately 5 km.

Deep resistivity imaging across the Northern and Central belts of the Southern Uplands [PDF]
, 1995 Magnetotelluric data from 16 soundings have provided a northwest-southeast traverse across the Northern and Central belts of the Southern Uplands. The 34 km profile extends from the Ordovician Portpatrick Formation (northwest of the Thornhill Basin ...

Study on the change characteristics of regional geoelectric fields
Journal of Earth System Science, 2019 In this study, we illustrate the temporal variations of the geoelectric field and geomagnetic field by data from eight geoelectric field stations and four geomagnetic field stations in Mainland China in 2011. The maximum entropy spectral estimation method (MEM) was used to process the data in our study. The results show that: (i) it is obvious seasonal

Geomagnetically Induced Currents in the Irish Power Network during Geomagnetic Storms
, 2016 Geomagnetically induced currents (GICs) are a well-known terrestrial space weather hazard. They occur in power transmission networks and are known to have adverse effects in both high and mid-latitude countries.

Space Weather, 2018 We forecast the global effects of space weather on the geoelectric and geomagnetic fields using a novel combination of methods. We use a realistic three‐dimensional (3‐D) model of Earth's electrical conductivity and a realistic representation of ...

Space Weather, Volume 24, Issue 1, January 2026.Abstract Geomagnetically induced currents (GICs) are telluric currents driven by space weather that can adversely impact high voltage transformers in electricity supply networks. It is often difficult to obtain transformer GIC data so ground based magnetometer data may be used to estimate the transformer GIC via complex modeling of both network and ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.Abstract Deep learning (DL) is an increasingly popular method for inverting the transient electromagnetic (TEM) data. Currently, DL‐based inversion for TEM data primarily employs supervised learning methods that rely on labeled data sets to train the network.

Seismic reflection and topography insights into Ries crater diameter and megablock zone
Meteoritics &Planetary Science, Volume 60, Issue 12, Page 2891-2912, December 2025.Abstract Most of the extensive crater‐wide geophysical studies at the Ries impact structure were made decades ago when the origin of the structure was still being debated. Although it is one of the most studied impact structures, its internal structure was not imaged in high resolution until recently.

A geomagnetic precursor to the 1979 Carlisle earthquake [PDF]
, 1982 A study of horizontal field transfer functions, in the period range 10-104 s, has been made for the 2 year period preceding the 1979 Carlisle earthquake (magnitude 5).
