Optimal site selection for Choutuppal geomagnetic observatory, based on geophysical evidence
Year: 2025
Type: article
Abstract: . The development of the stages of the Choutuppal magnetic observatory over last 15 years has enabled the effects of the natural environment like groundwater changes and lightning activity on the magnetic data to be evaluated. A new survey for total field anomalies and analysis of lightning data is carried out to understand the nature of the subsurface. Based on model from high resolution magnetic data and conductivity depth slices from ERT and EVRI surveys, the distribution of sandy regolith, saprolite, and granitic layers in the shallow subsurface to be delineated. This model provides information for selecting a location to install the magnetic observatory by taking into account topography, lightning effect, soil resistivity, low magnetic gradients, and distance from the recharge pond.
