Review of electric and magnetic fields accompanying seismic and volcanic activity
TL;DR: In this paper, magnetic, electric and electromagnetic field variations were obtained on Mt. Unzen in Japan, Reunion Island in Indian Ocean, the Long Valley volcanic caldera in California, and for faults in China and Russia, California and several other locations.
Journal ArticleDOI
ELF and VLF radio waves
TL;DR: A review of developments in ELF and VLF radio-wave propagation research over the last 50 years of the Journal of Atmospheric and Solar-Terrestrial Physics can be found in this paper.
Journal ArticleDOI
Ionospheric Precursors of Earthquakes; Recent Advances in Theory and Practical Applications
TL;DR: In this paper, a physical model was developed to bridge the traditional precursors of earthquakes and ionospheric ones, demonstrating that the latter belong to the same family, and a possible system of ground-based measurements and satellite monitoring was proposed for regional and global monitoring and possible short-term prediction of destructive earthquakes.
Journal ArticleDOI
A mechanism for the production of electromagnetic radiation during fracture of brittle materials
TL;DR: In this article, the feasibility of the charge separation model as the source of electromagnetic radiation received from the fracture of brittle materials is demonstrated, and an analytical expression and a finite difference method enable the calculation of currents flowing around the tip of a crack.
Journal ArticleDOI
Ionosphere plasma bubbles and density variations induced by pre‐earthquake rock currents and associated surface charges
TL;DR: In this paper, the authors formulated a coupling model for the stressed rock-Earth surface charges-atmosphere ionosphere system, where the stressed-rock acts as the dynamo to provide the currents for the coupling system.

Electrostatic effects in the coupling of upper atmospheric waves to ionospheric plasma
TL;DR: In this paper, a self-consistent solution was proposed for a variety of examples involving both acoustic and acoustic gravity waves. But the solution was not suitable for the case of the neutral-plasma coupling in the conjugate ionosphere.
Journal ArticleDOI
Variational electric fields at low latitudes and their relation to spread F and plasma irregularities
TL;DR: In this article, in situ measurements of variational electric fields at low latitudes, taken by OGO 6 satellite instruments, are analyzed and compared with other data on F region and spread-F structures.

Magnetic and Electric Signals Precursory to Earthquakes An Analysis of Japanese Data
TL;DR: In this article, magnetic and electric data of earthquake precursor amounting to 61 in number so far obtained in Japan are analyzed, and the relations between main shock magnitude (M), precursor time (T) and epicentral distance (D) are studied for precursors of five subdisciplines g (geomagnetic field change), earth currents (e), resistivity measured by electrodes having a long distance interval (R), resistivities measured by a resistivity variometer (r) and electromagnetic radiation (w).

Observations of seismo-electromagnetic earthquake precursor radiation signatures along Southern Californian fault zones: Evidence of long-distance precursor ultra-low frequency signals observed before a moderate Southern California earthquake episode
TL;DR: In this article, the authors report on observations of broadband ULF signals before and during the Upland quake of April 17, 1990 (Ms'='4.6), centered 200'km N of San Diego.
