“…In such a case, the length of the wire may significantly exceed the linear sizes of the polarization area because in case of horizontal locking the positively polarized wire may tie to a wire with any length and the opposite sign. Such a contour typology schematically coincides with the fact that the atmospheric electric precursors of earthquakes often appear quite far away from epicentres (Kachakhidze et al, 2003;Dunajecka et al, 2005;Pulinets et al, 2006;Liperovsky et al, 2008).…”

“…In case of a horizontal circuit the positively polarized conductor may be coupled with the opposite sign conductor having any length. Such topology of the circuit is quite handy if we take into consideration that electromagnetic precursors of earthquakes often appear quite far from the epicentres of main shocks (Tramutoli et al, 2001(Tramutoli et al, , 2005Kachakhidze et al, 2003;Dunajecka et al, 2005;Pulinets et al, 2006Pulinets et al, , 2007Liperovsky et al, 2008).…”

The model of self-generated seismo-electromagnetic oscillations of the LAI system

Abstract. Very low frequency (VLF) electromagnetic radiation (in diapason 1 kHz-1 MHz) in the atmosphere, generated during an earthquake preparation period, may be connected with the linear size characterising the expected earthquake focus. In order to argue this hypothesis, a very simple quasi-electrostatic model is used: the local VLF radiation may represent the self-generated (own) electromagnetic oscillations of interactive seismoactive segments of the lithosphere-atmosphere system. This model qualitatively explains the well-known precursor effects of earthquakes. In addition, using this model after diagnosing existing data makes it principally possible to forecast an expected earthquake with certain precision.As a physical basis of the working hypothesis is the atmospheric effect of polarization charges occurring in the surface layer of the Earth, it is possible to test the following constructed model in the Earth's crust, where the reason for polarization charge generation may be different from piezoelectric mechanism, e.g., some other mechanism.

“…Such drops in relative humidity usually are accompanied by an increase in the daily range of the air temperature variations. Pulinets et al (2006) have demonstrated for several recent important earthquakes that the daily temperature range have a similar pattern for all cases considered. The maximum of the daily temperature range usually is observed one week -5 days before the seismic shock.…”

Abstract. The paper examines the possible relationship of anomalous variations of different atmospheric and ionospheric parameters observed around the time of a strong earthquake (M w 7.8) which occurred in Mexico (state of Colima) on 21 January 2003. These variations are interpreted within the framework of the developed model of the Lithosphere-Atmosphere-Ionosphere coupling. The main attention is focused on the processes in the near ground layer of the atmosphere involving the ionization of air by radon, the water molecules' attachment to the formed ions, and the corresponding changes in the latent heat. Model considerations are supported by experimental measurements showing the local diminution of air humidity one week prior to the earthquake, accompanied by the anomalous thermal infrared (TIR) signals and surface latent heat flux (SLHF) and anomalous variations of the total electron content (TEC) registered over the epicenter of the impending earthquake three days prior to the main earthquake event. Statistical processing of the data of the GPS receivers network, together with various other atmospheric parameters demonstrate the possibility of an early warning of an impending strong earthquake.Keywords.

Abstract.A self adaptive approach (RST, Robust Satellite Technique) has been proposed as a suitable tool for satellite TIR surveys in seismically active regions devoted to detect and monitor thermal anomalies possibly related to earthquake occurrence. In this work, RST approach has been applied to 15 years of AVHRR (Advanced Very High Resolution Radiometer) thermal infrared observations in order to study the 6 April 2009 Abruzzo earthquake. Preliminary results show clear differences in TIR anomalies occurrence during the periods used for validation (15 March-15 April 2009) and the one (15 March-15 April 2008) without earthquakes with M L ≥4.5, used for confutation purposes. Quite clear TIR anomalies appears also to mark main tectonic lineaments during the preparatory phases of others, low magnitude(3.9
