“…Wiese and Martin, 1986). The colors are also seen in auroras (Sorokin and Chmyrev, 2014) but at ground level one would need a very intense primary ionization event of perhaps many tens of kilowatts per square meter. Could this give a significant radiation dose?…”

Earthquake light (EQL) mainly blue-white flashes from the ground, was observed coseismically during a New Zealand M7.1 earthquake, (4.47 am 4-Sep-2010 local time). A local production mechanism is most probable. The blue-white flash observations support the Freund et al. mechanism, i.e. shockwave disturbance creating electronic "holes" from ruptured peroxy bonds in quartz, and subsequent surface positive charge from the ground, followed by light emission during neutralization. Examination of video records shows the flash median length is about half a second and needs to be differentiated from the light during electricity supply short circuits. Observed ground-level white colors appear to result from very intense non-specific air ionization. Blue colors seem to be nitrogen emission with a short lifetime, succeeded by green oxygen emissions with longer lifetime followed by much lower intensity red. These were created by transient low-to-moderate voltages and probably include significant UV production. The maximum likely radiation dose is small, restricted to the skin, and equivalent at most to a few months natural background radiation. Calculations confirm the release of 222 Rn is not the major mechanism for creating earthquake light, and would contribute minimal radiation dose. Other unique observations are: streamers of light changing from blue to green as they passed from west to east, vertical sheets of blue-green light from cracks in an asphalt road surface, created by local shockwaves and shearing forces, daylight observation by fishermen of rapid linear undersea travel of blue light seconds before a 2011 M6.0 aftershock, and a mid-day green-blue glow over nearby hills containing a fault zone, shortly before the further destructive M6.3 earthquake, (12.51 pm 22-Feb-2011).Las luces de terremoto o EQL (del inglés "Earth Quake Light") son principalmente azul blancas y fueron cosísmicamente observadas durante un terremoto de magnitud 7.1 en Nueva Zelanda (4:47 a.m., 4 de septiembre de 2010, hora local). Es muy probable que el fenómeno haya sido producto de un mecanismo local. Las observaciones del destello azul blanco coinciden con el mecanismo de Freund y otros, esto es, la alteración de un movimiento sísmico que crea "agujeros" electrónicos a partir de lazos de ácido peroxi rotos en cuarzos, con carga positiva superficial consecuente del suelo, y seguida por la emisión de luz durante la neutralización. La revisión de grabaciones de video muestra que la duración del destello es de cerca de medio segundo y debe ser diferenciado de la luz generada por los cortos circuitos del fluido eléctrico. Los colores blancos observados a nivel del terreno parecen resultar de una intensa ionización aérea no específica. Los colores azules serían emisiones de nitrógeno con un corto período de duración, sucedidas por emisiones de oxígeno verde de mayor duración y seguidas por un rojo mucho menos intenso. Estos colores fueron creados por voltajes transitorios de bajo a moderados y probablemente incluyen una producción significativ...

“…In the frame of our model, the theory of generation of quasi-static electric field in the atmosphere-ionosphere system was developed, and the methods for calculation of electric field spatial distribution were elaborated.

This paper reviews modeling of the influence of earthquake (EQ) preparation processes on the ionosphere through the electric field and electric current occurring in the global atmosphere-ionosphere electric circuit. Our consideration is based on the satellite-and ground-based experimental data of electric fields, plasma and electromagnetic perturbations obtained for several days before an EQ. We have ruled out the models which are not consistent with the experimental data on the electric fields in the ionosphere and also on the ground surface. There has then been proposed a new model of the generation of electric field on the basis of injection of charged aerosols into the atmosphere, and we discuss the mechanism of lithosphere-atmosphere-ionosphere coupling. It is then shown that such changes in the electric field within the ionosphere induce a variety of plasma and electromagnetic phenomena associated with an impending EQ.

“…They considered both the sources of AGW generation and the processes accompanying the propagation of these waves into the ionosphere. Essentially another physical idea of the latter is used in the electrodynamical model of plasma and electromagnetic disturbances accompanying the EQ preparation, which has been discussed in the reviews by Sorokin (2007), Sorokin and Chmyrev (2010), and Sorokin and Hayakawa (2013). First this model allows us to account for the results of observation of quasi-static electric field both in the ionosphere and on the Earth's surface that cannot be explained by other models.…”

This paper is devoted to the use of an electrodynamical model for lithosphere -atmosphere -ionosphere (LAI) coupling to explain plasma and electromagnetic earthquake (EQ) precursors. Our consideration is based on the calculation results of electromagnetic perturbations and ionospheric irregularities accompanying the electric field and electric current occurring in the global atmosphere -ionosphere electric circuit. Our theoretical results are confirmed by satellite-and ground-based experimental data of plasma and electromagnetic perturbations obtained for several days before an EQ. It is shown that the growth of current in the global circuit might result in the AGW (acoustic gravity wave) instability in the ionosphere, the formation of field-aligned current and plasma irregularities, magnetic field ULF oscillations and electromagnetic ELF radiation, spectral broadening of VLF transmitter signals registered by satellites, depressions of ULF magnetic pulsations, VHF radio emissions generated in the troposphere and propagation of the signals of a VHF transmitter behind the horizon. Moreover, the generation of electric current in the global circuit is accompanied with the modification of D, E and F ionospheric layers. All of these phenomena are shown to be attributed just to a single cause; namely, the variation of conducting electric current in the global circuit by the injection of charged aerosols into the atmosphere during seismic activity.
