Magnetotelluric monitoring of geodynamic processes

open access: yesAnnals of Geophysics, 1997
Electromagnetic (EM) monitoring of geodynamic processes can be based on the two different seismo-electrical phenomena: a change in resistivity of some geological cross-sections and a generation of EM fields of internal (geodynamic) origin.

The effect of earth tides as observed in seismo-electromagnetic precursory signals [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2009
Studies on the effect of earth tides in triggering earthquakes (EQs) had a great progress in recent years, which has provided convincing evidence of earth tides in EQ triggering.

Multi-component ground-based observation of ULF waves: goals and methods

open access: yesAnnals of Geophysics, 1998
A revival of the combined magnetic and telluric electric measurements at magnetic observatories is suggested.A number of problems, where such observations might be very helpful, are outlined: 1) the account for the resonance structure of the ULF field ...

The Data Comparison of Electron Density Between CSES and DEMETER Satellite, Swarm Constellation and IRI Model

open access: yesEarth and Space Science, 2021
The China Seismo‐Electromagnetic Satellite (CSES), which is also called ZhangHeng‐1 (ZH‐1), was successfully launched on February 2, 2018. Evaluating the quality of observation data is imperative for the satellite mission and users.

Earthquake Prediction: Seismo‐Electromagnetic Phenomena

open access: yesEos, Transactions American Geophysical Union, 1996
Earthquake Prediction: Seismo‐Electromagnetic Phenomena is a review of research on electromagnetic emissions (EME) as precursors to earthquakes. The authors state in the introduction that the book is primarily based on their own work, so there is heavy emphasis on the Russian literature.

Quantitative Examination of Piezoelectric/Seismoelectric Anomalies from Near-Surface Targets

open access: yesGeosciences, 2017
The piezoelectric and seismo-electrokinetic phenomena are manifested by electrical and electromagnetic processes that occur in rocks under the influence of elastic oscillations triggered by shots or mechanical impacts.

Seismic Waves Do Sense Fracture Connectivity: Experimental Validation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Fracture connectivity is a key parameter controlling fluid flow throughout the Earth's crust. While some theoretical and numerical studies suggest that seismic waves are sensitive to fracture connectivity, an experimental validation of this critically important phenomenon was so far unavailable.

Seismo‐Acoustic Detection and Localization of Iceberg Collapse in Atka Bay, Antarctica

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract On 12 January 2022, an iceberg collapsed at the edge of frozen Atka Bay, Antarctica. The event generated seismic, hydroacoustic, and atmospheric infrasound waves recorded by a local network comprising land‐ and iceshelf‐based seismometers, an underwater hydrophone, and an on‐ice infrasound array.

Four‐Peak Structure on Equatorial Ionization Anomaly Crests During the May 2024 Geomagnetic Storms

open access: yesSpace Weather, Volume 23, Issue 12, December 2025.
Abstract This study investigates the four‐peak electron density structure in the Equatorial Ionization Anomaly (EIA) during the intense geomagnetic storms of 10–20 May 2024, utilizing dayside data at ∼500 km from the China Seismo‐Electromagnetic Satellite (CSES‐01).
