Abstract: Abstract: We used the informational methods of the Shannon entropy power and the Fisher Information Measure to analyze the time dynamics of one year of semi-daily values of apparent resistivity, calculated on the base of the magnetotelluric (MT) monitoring at Penghu Island, Taiwan. The performed statistics indicate that the day-time measurements present higher disorder and lower organization than the night-time measurements. Such difference is more evident for the high-frequency band of resistivity data, which suggests that possibly some source of the electromagnetic field could be of anthropic origin. Furthermore, we also note the characteristics of so-called MT dead-band with the periodicity of ∼10 s could be revealed in the high values of Shannon entropy power.
