1D model validation for the variations in earth's apparent resistivity of barricelle site (Southern Italy)

Data from a magnetotelluric (MT) monitoring system installed in Agri Valley (Southern Italy) have been used to study the fluctuations of Earth's apparent resistivity. Using the detrended fluctuation analysis (DFA), suited for determining scaling behaviour in nonstationary data, the existence of temporal correlations in the resistivity time series was revealed, mainly associated with resistivity changes in shallow layers.
