Geomagnetic Earthquake Precursors Improvement Formulation on the basis of SKO (Skopje) and PAG (Intermagnet) Geomagnetic Data
In this paper we show that the simple analysis of the local geomagnetic field behaviour can serve as reliable imminent precursor for regional seismic activity increasing. As the first step the problem was investigated using one- component Dubna fluxgate magnetometer. The result of 2001-2004 Sofia monitoring confirmed many old papers for connection between Earth tide (Sun- Moon tides as earthquakes trigger) and jump (Geomagnetic quake) of daily averaged one minute standart deviation of the geomagnetic field. The second step (2004-present), which included analisys of three-component Danish fluxgate magnetometer data, worked in Skopje Seismological observatory, confirmed the first step result. The analysis of INTERMAGNET data stations around which was happened stronger earthquakes also confirmed our result. The distribution of time difference between the times of such earthquakes and local daily averaged tide vector movement for impending tide extreme confirms our estimate that the increasing seismicity is realized in time window about +/- 2.7 days. The Complex program for researching the possibility for when, where and how earthquakes prediction is proposed as well as the short description of FORTRAN codes for analysis of earthquakes, geomagnetic and tide data, their correlations and visualization.

The electromagnetic fields under, on and over Earth surface as when, where and how earthquake precursor
It is given an attempt for statistical estimation of when earthquake prediction for Balkan- Black Sea region using the geomagnetic field signal. The preliminary test of the approach for England (Hartland), Turkey (Kandilli) and India (Alibag) regions is presented. The research step by step program for creating when, where and how earthquake prediction region Network system on the basis of the experimental data for geomagnetic field, electro-potential distribution in the Earth crust and atmosphere, temperature Earth crust distribution, gravitational anomaly map, season and day independent temperature depth distribution, water sources parameters (debit, temperature, chemical composition, radioactivity), gas emissions, ionosphere condition parameters, Earth radiation belt, Sun wind, crust parameters (strain, deformation, displacement) and biological precursors is proposed. The achievements of tidal potential modeling of Earth surface with included ocean and atmosphere tidal influences, many component correlation analysis and the nonlinear inverse problem methods in fluids dynamics and Maxwell equations are crucial. The today almost real time technologies GIS for archiving, analysis, visualization and interpretation of the data and non- linear inverse problem methods for building theoretical models for the parameter behaviors, correlations and dynamics have to be used.
