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.

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.
Journal ArticleDOI

Shear velocity structure of the laterally heterogeneous crust and uppermost mantle beneath the Indian region

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.

Seismic waves and earth structure in the Canadian shield

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.

Earthquakes of peninsular India—a seismotectonic study

TL;DR: In this article, a detailed consideration of the historical as well as recent earthquake data, and a catalog of earthquakes from the earliest time through 1974 occurring within the region, 5°N-28°N; 67.5°E-90°E, is prepared.
