Short-term prediction of ionospheric parameters based on auto-correlation analysis
Ionospheric F region prediction auto-correlation method
2015/10/8
A prediction method based on a simple auto-regressive model has been developed for short-term prediction of ionospheric characteristics. The method determines the auto-correlation function for the hou...

The variations of the b coefficient in the frequency-magnitude relationship for earthquakes which occurred at Mt. Etna from 01/01/90 to 31/12/92 are analyzed; the completeness threshold for our earthq...
Energy and polarization of the telluric field in correlation with seismic activity in Greece
earthquake precursor telluric field electric field polarization
2015/9/28
Many attempts have been made to disclose anomalous changes of the electromagnetic field in relation with tectonic earthquakes. We tentatively develop a new approach based on the energy and polarity of...
Correlation of pressure stimulated currents in rocks with the damage parameter
Pressure Stimulated Current (PSC) damage parameter fracture
2015/9/2
Pressure Stimulated Current (PSC) experiments were conducted on marble samples to correlate PSC with the damage parameter, D. The phenomena and procedures taking place in the vicinity of the fracture ...

Locating a scatterer in the active volcanic area of Southern Peru from ambient noise cross-correlation
Interferometry Wave scattering and diffraction Volcanic arc processes
2014/4/10
We report on a strong scatterer of seismic energy in the 5–10 s period range located in the volcanic arc of Southern Peru. It is superficially like an active noise source in that it produces a continu...
The lack of correlation betweenflat slabs and bathymetric impactors in South America
flat slab subduction South America
2014/4/10
Flat slab subduction has been attributed to various causes including mantle wedge dynamics, overriding by the upper plate, age of the subducting plate, and subduction of anomalously thick oceanic crus...
Maximum-likelihood estimation of lithospheric flexural rigidity, initial-loading fraction, and load correlation, under isotropy
flexural rigidity lithosphere topography gravity maximum-likelihood theory
2012/5/28
Topography and gravity are geophysical fields whose joint statistical structure derives from interface-loading processes modulated by the underlying mechanics of isostatic and flexural compensation in...
