Spectrum characteristics of geoelectric field variation

Acta Seismologica Sinica, 2007
The spectrum characteristics of geoelectric diurnal variation and geoelectric storm have been identified by maximum entropy method, based on geoelectric data from seven stations in the Chinese mainland, including Jiayuguan, Changli and Chongming. The study shows that, in geoelectric diurnal variation, the amplitude of the 12 h semidiurnal wave is the ...

Study on the variation characteristics of the geoelectric field preceding earthquakes

Acta Seismologica Sinica, 2004
Earthquake events occurred in Nantong, Jiangsu Province on Nov. 3, and Dec. 25, 2001 in which the biggest magnitudes were M L=3.8 and M L=4.1, respectively. This paper firstly explains the principle of the eliminating noise method by the multi-dipole observation system of geoelectric field.

Analysis of the Geoelectric Field in Sweden Over Solar Cycles 23 and 24: Spatial and Temporal Variability During Strong GIC Events

Space Weather, 2023
Geomagnetic storms can produce large perturbations on the Earth magnetic field. Through complex magnetosphere-ionosphere coupling, the geoelectric field (E) and geomagnetic field (B) are highly perturbed.

Excitation of fields in geoelectric experiments

Izvestiya, Physics of the Solid Earth, 2007
The paper discusses the premises and possibilities for expanding the experimental base of controlled-source geoelectrics. A nonstationary electric field (E-field, E-mode, and TM-field) and the means for its excitation are examined as a reserve. The appendix presents a compact description of the mathematical apparatus applicable to results of transient ...
