Study of crustal movements across Shali Thrust in the area of Shanan (Joginder Nagar) in Himachal Pradesh

Abstract

Repeated observations involving geodetic triangulation and precision leveling were carried out by No. 14 Party of the Geodetic and Research Branch across a suggested position of the Shali Thrust near Shanan (Joginder Nagar), during 1975–1976 and again during 1977–1978, for recent crustal movements. From an analysis of the results obtained for these two seasons, it is inferred that horizontal movements of the order of 0.5 cm to 4 cm and vertical movements of the order of 1 cm to 5 cm have taken place during the two years interval between the observations.
