IUGG XXIV General Assembly July 2-13, 2007 Perugia, Italy (S) - IASPEI - International Association of Seismology and Physics of the Earth's Interior JSS010 Oral Presentation 2069 Progress in Understanding of Lithosphere-Atmosphere-Ionosphere Coupling Prof. Sergey Pulinets Space Physics Depratment Institute of Geophysics Dimitar Ouzounov, Alexander Karelin, Kirill Boyarchuk The Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) model created recently is able to explain simultaneously the thermal anomalies observed in the boundary layer (BL) of atmosphere and ionospheric anomalies observed in all layers of the ionosphere before strong earthquakes by common physical mechanism, having as a principle source the air ionization by increased radon release over active tectonic faults. We name these anomalies as thermal and ionospheric branches of the model. But these branches are not independent; they interact and provide the energy one to another for selfdevelopment. Electric properties of the large ion clusters change the chemical potential (work function of evaporation) what makes the clusters more stable and permit to attach more water molecules and consequently to release more latent heat. The thermal energy released during the process of water molecules attachment to ions creates the upward convective flux which is the source of the additional electric field generation and amplification. The intermediate products of this interaction between branches are increased concentration of the aerosols in the boundary layer and formation of so called earthquake clouds. All the parts of the presented model are supported by satellite and ground based measurements of atmospheric and ionospheric parameters of major recent earthquakes. Keywords: lai coupling model, ionization, thermal ionospheric anomalies
IUGG XXIV General Assembly July 2-13, 2007 Perugia, Italy (S) - IASPEI - International Association of Seismology and Physics of the Earth's Interior JSS010 Oral Presentation 2070 Multisensor Approach of Analyzing Atmospheric/Ionospheric EM Signals Connected with Major Earthquake Activities Dr. Dimitar Ouzounov WG EMSEV EMSEV IAGA Sergey Pulinets, Guido Cervone, Menas Kafatos, Michel Parrot, Patrick Taylor We present a possible relationship between tectonic stresses, electro-chemical and thermodynamic processes in the Earths crust and atmosphere with ionospheric plasma and ground- atmosphere electromagnetic (EM) field variations as a potential signature of electromagnetic (EM) phenomena that are related to earthquake activity, either pre-, co- or post seismic.Using data from: (1) polar orbiting MODIS, onboard NASAs Terra and Aqua; (2) AIRS (on Aqua); (3) NOAA/AVHRR; (4) geosynchronous weather satellites (GOES and METEOSAT); (5) DEMETER and; (6) GSP/TEC; we have analyzed: surface emissivity; sea and land surface temperature (LST); emitted earth radiation (OLR); air temperature; surface latent heat flux (SLHF); Total Electron Content, TEC (GPS /TEC); quasi-continuous electrical fields; and thermal plasma parameters.A reference level was created from multi-year data (LST, SLHF, OLR, and VLF) by systematically comparing them with recent satellite observations to determine meaningful statistics that can be applied to anomalous signals prior to an earthquake. Our rationale for using this complement of observations is that there are insufficient spatial and temporal coverage of any one of these pre-cursor signals on the global scale. The advantage of our approach is to enable multiple and previously validated physical measurements to be integrated into one framework with the latest theoretical models of seismo-electomagnetic generation and propagation and to provide feedback on data gaps that may then be acquired in the future from new missions. The significance of our satellite based multi-sensor approach was defined through analyzing recent (2000-2006) worldwide strong earthquakes and applying the techniques used to capture the EM anomalies. This joint approach provides an opportunity for a comprehensive study of Earth electromagnetic environment, and can be used to understand the relationship between seismic-tectonic processes in the solid Earth and surfaceatmosphere-ionosphere variability.

We present a possible relationship between tectonic stresses, electro-chemical and thermodynamic<br />
processes in the Earths crust and atmosphere with ionospheric plasma and ground- atmosphere<br />
electromagnetic (EM) field variations as a potential signature of electromagnetic (EM) phenomena that<br />
are related to earthquake activity, either pre-, co- or post seismic.Using data from: (1) polar orbiting<br />
MODIS, onboard NASAs Terra and Aqua; (2) AIRS (on Aqua); (3) NOAA/AVHRR; (4) geosynchronous<br />
weather satellites (GOES and METEOSAT); (5) DEMETER and; (6) GSP/TEC; we have analyzed: surface<br />
emissivity; sea and land surface temperature (LST); emitted earth radiation (OLR); air temperature;<br />
surface latent heat flux (SLHF); Total Electron Content, TEC (GPS /TEC); quasi-continuous electrical<br />
fields; and thermal plasma parameters.A reference level was created from multi-year data (LST, SLHF,<br />
OLR, and VLF) by systematically comparing them with recent satellite observations to determine<br />
meaningful statistics that can be applied to anomalous signals prior to an earthquake. Our rationale for<br />
using this complement of observations is that there are insufficient spatial and temporal coverage of any<br />
one of these pre-cursor signals on the global scale. The advantage of our approach is to enable multiple<br />
and previously validated physical measurements to be integrated into one framework with the latest<br />
theoretical models of seismo-electomagnetic generation and propagation and to provide feedback on<br />
data gaps that may then be acquired in the future from new missions. The significance of our satellite<br />
based multi-sensor approach was defined through analyzing recent (2000-2006) worldwide strong<br />
earthquakes and applying the techniques used to capture the EM anomalies. This joint approach<br />
provides an opportunity for a comprehensive study of Earth electromagnetic environment, and can be<br />
used to understand the relationship between seismic-tectonic processes in the solid Earth and surfaceatmosphere-ionosphere<br />
