High resolution electromagnetic methods and low frequency dispersion of rock conductivity
electromagnetic sounding induced polarization frequency dispersion of conductivity resolution of sounding mathematical modelling
2015/10/8
The influence of frequency dispersion of conductivity (induced polarization) of rocks on the results of electromagnetic (EM) sounding was studied on the basis of calculation of electric field of verti...
The temporal and spatial variations of low frequency geomagnetic pulsations at polar cusp and cap latitudes
Geomagnetic pulsations Antartica
2015/10/8
Geomagnetic field measurements at two Antarctic stations are compared during two weeks in the local summer (January 1-15, 1992). Low frequency (0.6-6 mHz) pulsations are observed at each station near ...
Slow earthquakes and low frequency tremor along the Apennines,Italy
Slow earthquakes Tremor Apennines
2015/9/1
This paper reviews the main observations on slow earthquakes and low frequency tremor made along the Apennines,the main seismic active zone of Italy. These observations have been made using a geodetic...
Possible precursor to the March 11, 2011, Japan earthquake: ionospheric perturbations as seen by subionospheric very low frequency/low frequency propagation
Earthquake predictio Ionospheric perturbatio VLF/LF propagation
2015/8/24
This study reports on a possible very low frequency/low frequency (VLF/LF) subionospheric precursor to a recent earthquake in Japan. As the epicenter of this large Japanese earthquake on March 11, 201...
