Abstract

In planning a magnetotelluric survey, there are several requirements to consider in order to record high-quality electromagnetic time series for geological investigation. In this paper, we present an example of a magnetotelluric field survey recently conducted in the Nógrád–Gömör Volcanic Field (Northern Pannonian Basin) during the summer of 2024, focusing on the recommended conditions for magnetotelluric station deployment. We begin with the geological goals and the motivation behind the magnetotelluric survey, followed by a suitable site selection, and conclude with some direct electromagnetic field observations from the time series obtained. Finally, we summarize the preliminary results of the magnetotelluric field campaign and suggest potential improvements that could enhance the quality of future field measurements.
