摘要

Geological and magnetic features were interpreted using IRS-P6 (LISS-III) and aeromagnetic data respectively. Historical rainfall data and the water-table fluctuations were also analysed and integrated with the above in conjunction with ground truth information. It is observed that the intrusion activity of the dykes had disturbed the fracture network, resulting in filling up of pore spaces in the weathered columns. Lineaments across the dykes, the associated pediment and the weathered pediplain have more porosity and permeability. The accumulation and rising of groundwater flow is influenced by the above structural set-up. It is concluded that significant amount of base flow had resulted in hydro-loading and was responsible for the micro-seismicity.
