The magnetotelluric method (MT) consists in the observation of the surface natural variations of the electromagnetic field in a broad range of periods. The apparent resistivity is proportional to the modulus of the surface impedance, which is the tensorial relation between the horizontal...

The Fisher–Shannon information (FS) plane, defined by the Fisher information measure and the Shannon entropy power, is used to investigate the complex dynamics of magnetotelluric data of three stations in Taiwan. In the FS plane the electric and magnetic components are significantly separated,...
