Abstract
Landslides are one of the many catastrophic events which result in massive destruction and
loss of lives across the globe. Hence, an appropriate forecasting technique is essential in
order to predict such potential weak slip planes which may eventually lead to landslides.
Here, we present a study where Fracture Induced Electromagnetic Radiation (FEMR) tech-
nique has been used to identify such regions of potential “activity” in a study area around
IISER Bhopal Hill, India, stretched along a length of approximately 1 km. The hill is
majorly composed of basaltic rocks belonging to the Deccan traps which have been heav-
ily weathered and have resulted in the formation of unconsolidated soil cover. In numerous
locations, it has been observed that natural gullies have formed as a result of the breakage
of masses from weak slip planes. In this study, we have taken linear measurements along
four diferent profles along and across the hill using a portable measuring device ANGEL-
M. Anomalously high amplitudes of FEMR values are obtained in the regions which con-
sist of weak slip planes which can be considered to be potential zones of future landslides.
The results were further verifed by calculating the factor of safety for a few locations along
the profles where anomalies in the FEMR data were compared. Consequently, predicting
areas prone to natural calamities such as landslides has always been a priority in terms of
current research. Hence, we have made an active endeavor to propose a new technique in
order to identify landslide-prone areas by detecting the adjoining weak slip planes.
