Remote sensing-GIS and GPR studies of two active faults, Western Gangetic Plains, India

Abstract Northern parts of the Ganga–Yamuna Interfluve in the Gangetic Plains, India have been investigated by remote sensing and Ground Penetrating Radar (GPR) techniques. Digital analysis of remote sensing data and Geographical Information System (GIS) techniques were used to locate a new active transverse Muzaffarnagar Fault and confirmed an earlier described Solani-II Fault in almost flat or gently sloping terrain. The Solani-II and Muzaffarnagar faults are members of two major systems of surficial faults i.e. longitudinal and transverse faults, respectively. Longitudinal faults are curvilinear in nature, trending N–S in the northern regions and veering to E–W in the southern regions of the plains and transverse faults are normal to the longitudinal faults occurring in the Upper Gangetic plains. GPR survey was carried out by common offset method across the Muzaffarnagar and the Solani-II faults, using a 100 MHz antenna. Our GPR data indicate that both regions around the Solani-II Fault and Muzaffarnagar Fault are characterized by 2–3 major steeply dipping normal faults at shallow depth (
