A deterministic seismic hazard map of India and adjacent areas.
TL;DR: In this paper, a seismic hazard map of the territory of India and adjacent areas has been prepared using a deterministic approach based on the computation of synthetic seismograms complete with all main phases.

Lithospheric Mantle Deformation beneath the Indian Cratons.
Om Prakash Pandey,P.K. Agrawal +1 more
TL;DR: The study indicates a large‐scale deformation of the cratonic mantle lithosphere beneath the Indian shield since the Mesoproterozoic caused by various geodynamic causes, challenging the idea of stability of deep continental roots.
Journal ArticleDOI
Super-mobility of hot Indian lithosphere
TL;DR: Negi et al. as mentioned in this paper studied the super-mobility of hot Indian lithosphere and found that the Indian subcontinent does not have the characteristics of a typical shield zone and that it has higher radioactivity, smaller viscous drag, lower density and a well defined low-velocity zone as compared to other shield areas of the world.

Shear‐velocity structure of the crust and upper mantle beneath the Tibetan Plateau and southeastern China
TL;DR: In this article, the velocity structure of the crust and upper mantle beneath southern China with special emphasis on the Tibet region was studied. But the model for Tibet derived does not have a distinct lid and has a positive velocity gradient in the crust, suggesting crustal shortening.

Shear velocity structure of the laterally heterogeneous crust and uppermost mantle beneath the Indian region
G. Mohan,S. S. Rai,G.F. Panza +2 more
TL;DR: In this paper, the shear velocity structure of the Indian lithosphere is mapped by inverting regionalized Rayleigh wave group velocities in time periods of 15-60 s. The authors used the Hedgehog Monte Carlo technique to obtain the velocity structure for each geologic unit, revealing distinct velocity variations in the lower crust and uppermost mantle.

The Early Structural Evolution and Anisotropy of the Oceanic Upper Mantle
TL;DR: In this article, the dispersion of Love and Rayleigh waves in the period range 17-167 s is used to detect the change in the structure of the upper mantle as the age of the sea-floor increases away from the mid-ocean ridge.

TL;DR: In this paper, a theoretical layered model of the crust and upper mantle consistent with the various types of data has been derived by an inversion method employing least-squares curve-fitting of phase velocity data.

Himalayan transverse faults and folds and their parallelism with subsurface structures of North Indian plains
TL;DR: A large number of fractures, faults and folds trending normal and oblique to the Himalayan tectonic trend have been recognized in recent years as discussed by the authors, implying a certain genetic connection between the two sets.
