On the fluctuation spectra of seismo-electromagnetic phenomena [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2011
In order to increase the credibility on the presence of electromagnetic phenomena associated with an earthquake, we have suggested the importance of the modulation (or fluctuation) seen in the time-series data of any seismogenic effects.
