Abstract

We investigated the multifractal structure of magnetic field H measured by magnetotelluric stations installed at three different sites in Taiwan, characterized by different site conditions. Magnetotelluric data include three components of the magnetic field H. We applied the multifractal detrended fluctuation analysis (MF-DFA) to magnetic magnitude time series (evaluated as the L 2 norm). Our findings point out to a significant discrimination among these data in terms of multifractal characteristics of the signals, indicating a strong influence of the environmental settings of the measurement sites on the temporal fluctuations of magnetic field H. Such results highlight the usefulness of the MF-DFA in discriminating dynamics in observational time series of magnetotellurics.
