“…Occasionally overlapping background signals that occur simultaneously in the sought process may shift this process in time and cause its transformation. The direct influence of the components of the seismic event vector of the magnetic field at the locations of magnetic stations is strongly non uniform [29].…”

Earthquake recurrence is depicted on the basis of the time following subsequent seasons at the coastal regions of Pakistan. Recurrence time for intricate shock waves is simulated by using earth positions at equinoxes and perihelion-aphelion positions of the earth from the Sun. In connection to the spatial and temporal behavior of earth, the external geomagnetic variation is significant not only influenced by the distances between the Sun and earth and annual revolving period of earth around the Sun at heliocentric path but also affected by a lunar revolving period on an elliptical path around the earth. The Apparent path of the Sun during the year where earth is the center of the celestial sphere and relative to earth, the Sun appears on ecliptic sphere which intersects the celestial equator in two points known as the vernal equinox of 21 st march and autumn equinox of 21 st September. The perihelion position on earth is nearest to the Sun and aphelion is the furthest position of the earth from the Sun, these are empirically distributed on the basis of mutual interaction. The seasonal effects are recognized by the wavelet characterization on maximum amplitudes of shock waves with reference to vernal-autumn equinoxes of distributed perihelion-aphelion periods. The seasonal period of geomagnetic seismicity is a manifestation of the mean time between earthquakes within a specified region where many faults are activated. The cyclic nature of earthquakes and geomagnetic influences on seismic waves by stress-strain tectonic process and releasing energy for the relaxation mechanism are experienced in nature, therefore the issues relevant to their aphelion-perihelion periodicities, influential conditions of geomagnetic instability and their coupling for shock waves propagation are tackled by the wavelet applications.

“…A wide complex of geophysical research is applied to studying the phenomena occurring and diagnostics of seismic activation of the region. It is primarily direct method: seismic survey and registration of radiation associated with the deformation and crushing of rock-the acoustic and low-frequency electromagnetic radiation, gas emanations [1][2][3][4][5] Preparation processes are reflected variations of anomalies of temperature and pressure, electrical resistivity of the earth's crust [6][7][8][9][10][11]. Due to the close interaction of geophysical shells, the Earth abnormal physical fields of the lithosphere in the process of earthquake preparation excite anomalies in the atmosphere and ionosphere.…”

The calculation method of the location of the singular generalized current source according to synchronous measurements of the magnetic field in the remote points is proposed. It is designed for the continuous monitoring of changes of the degree of electromagnetic heterogeneity of the geophysical environment. Regular fluctuations of the apparent distance to the effective single source were recorded according to the magnetic data of the observatories in Japan 2009-2011. They are connected with the rhythm of the geodynamic processes in the vicinity of the station Kakioka. The most significant decrease in the apparent distance was registered in connection with the seismic activation of the region, including the catastrophic earthquake of March 11, 2011 with a magnitude of M = 9.1. The anomalous behavior of the apparent parameters of the generalized source was displayed not less than two weeks before the earthquake. Characteristic changes of the curves were registered in the period of three months.
