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.

Rethinking earthquake-related DC-ULF electromagnetic phenomena: towards a physics-based approach [PDF]

open access: yes, 2011
Numerous electromagnetic changes possibly related with earthquakes have been independently reported and have even been attempted to apply to short-term prediction of earthquakes.

Wavelet analysis of the LF radio signals collected by the European VLF/LF network from July 2009 to April 2011 [PDF]

open access: yes, 2012
In 2008, a radio receiver that works in very low frequency (VLF; 20-60 kHz) and LF (150-300 kHz) bands was developed by an Italian factory. The receiver can monitor 10 frequencies distributed in these bands, with the measurement for each of them of the ...

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.

SEISMO-ELECTROMAGNETIC PHENOMENA IN TECTONICALLY ACTIVE REGIONS [PDF]

open access: yes, 2010
This work presents a research plan that aims to monitor seismo-electromagnetic signals in seismic active regions. Two effects will be considered: electromagnetic field emissions and radio broadcastings.

Electro-Magnetic Earthquake Bursts and Critical Rupture of Peroxy Bond Networks in Rocks

open access: yes, 2006
We propose a mechanism for the low frequency electromagnetic emissions and other electromagnetic phenomena which have been associated with earthquakes. The mechanism combines the critical earthquake concept and the concept of crust acting as a charging ...

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.
