Day-time variations of foF2 connected to strong earthquakes
Day-time variations foF2 strong earthquakes
2009/12/16
The statistical analysis of the characteristic frequency foF2 of the Earth's ionosphere averaged over mid-day hours – from 11:00 till 17:00 h LT – is carried out. Disturbances of foF2 connected to ear...
Dynamics of multifractal and correlation characteristics of the spatio-temporal distribution of regional seismicity before the strong earthquakes
multifractal and correlation characteristics spatio-temporal distribution regional seismicity
2009/12/11
Investigations of the distribution of regional seismicity and the results of numerical simulations of the seismic process show the increase of inhomogenity in spatio-temporal distribution of the seism...
Variations of phase velocity and gradient values of ULF geomagnetic disturbances connected with the Izu strong earthquakes
phase velocity gradient values ULF geomagnetic disturbances Izu strong earthquakes
2009/12/11
Results of study of anomaly behavior of amplitudes, phase velocities and gradients of ULF electromagnetic disturbances (F = 0.002 – 0.5 Hz) before and during a seismic active period are presented. Inv...
Strong earthquakes can be predicted: a multidisciplinary method for strong earthquake prediction
Strong earthquakes a multidisciplinary method strong earthquake prediction
2009/12/10
The imminent prediction on a group of strong earthquakes that occurred in Xinjiang, China in April 1997 is introduced in detail. The prediction was made on the basis of comprehensive analyses on the r...
The pecularities of shear crack pre-rupture evolution and distribution of seismicity before strong earthquakes
shear crack pre-rupture evolution seismicity strong earthquakes
2009/12/9
Several methods are presently suggested for investigating pre-earthquake evolution of the regions of high tectonic activity based on analysis of the seismicity spatial distribution. Some precursor sig...
A statistical analysis of several ionospheric parameters before earthquakes with magnitude M > 5.5 located less than 500 km from an ionospheric vertical sounding station is performed. Ionospheric effe...
Comparison of simultaneous variations of the ionospheric total electron content and geomagnetic field associated with strong earthquakes
the ionospheric total electron content geomagnetic field strong earthquakes
2009/12/9
In this paper, perturbations of the ionospheric Total Electron Content (TEC) are compared with geomagnetic oscillations. Comparison is made for a few selected periods, some during earthquakes in Calif...
Hydrogeochemical precursors of strong earthquakes in Kamchatka: further analysis
Hydrogeochemical precursors strong earthquakes Kamchatka further analysis
2009/12/9
In this paper, we allow for the cross-correlation found between the gas data sets and in some cases, between the ion data sets. No cross-correlation has been found between gas and ion content data. An...
