“…The crustal shortening in the Himalaya between these two continents based on neo-tectonic deformation (Lave and Avouac, 2000;Malik and Mohanty, 2007) and global positioning system (GPS) motion rates (Bilham et al, 1997;Jade et al, 2007;Burgess et al, 2012;Verma and Bansal, 2012) shows an approximately 20 mm/yr. of convergence.…”

“…A national GNSS programme was launched more than two decades ago in India for monitoring the crustal deformation to facilitate constraining the Indian plate movement, estimation of strain accumulation and convergence rates in the regions of high seismic activity (Verma and Bansal 2012a). Under the program, about a dozen permanent GPS receivers were established in the EH region at identified locations.…”

Mitigation of geological hazards through science and engineering applications is one of the most effective ways to reduce their impact on human life and local infrastructure. It involves precise mapping of hazards, assessment of their potential, monitoring, early warning, geotechnical treatment, design of vital infrastructural facilities and creating awareness at local levels. Several such initiatives have been taken at government level to deal with the earthquakes and landslides in the eastern Himalayan region. These efforts facilitated identification of potential areas and sites, susceptible to future events and helped in improving our understanding of crustal structure, geodynamics, tectonics, seismogenesis, and soil properties, etc. The paper highlights details of the major initiatives, significant achievements, and priorities to help in better mitigation of earthquake and landslide hazards in the eastern Himalayan region.

“…The middle and upper Proterozoic strata are mainly distributed in cratonic rifts, sag basins, and the linear grabens, with limited distribution, little change in lithology, and low level of metamorphism. The shield structure is well reflected in the first detail field of the Bouguer anomaly, according to which the tectonic units of the IND basement can be divided (Amaldev et al, ; Verma & Bansal, ).…”

The evolution correlation between the North China Craton (NCC) and the Indian Shield (IND) is very important for plate reconstruction. Recently, more and more research results show that the NCC and IND had been pieced together in the Paleoproterozoic. In order to analyse the correlation between the NCC and IND, we use the latest gravity and magnetic data to study deep geophysical characteristics of the NCC and IND respectively, and we also use a two‐dimensional discrete wavelet transform method to discuss the division scheme of the basement tectonic unit in the Paleoproterozoic at the point of gravity and magnetic field. On the basis of gravity and magnetic anomalies, the NCC is divided into the Eastern Block, Western Block, and the Trans‐North China Orogen, which are further divided into the secondary tectonic zones and blocks. The IND is divided into the Southern Block, the Northern Block, and the Central Indian Tectonic Zone, and they also are further divided into secondary tectonic zones and ancient cratons. On the basis of that, according to the four Paleoproterozoic plate assemblage schemes proposed by predecessors, we compared the geophysical characteristics and the correlation through the regional gravity and magnetic anomalies between the two continents. The results show that the faults and tectonic boundaries in the Trans‐North China Orogen of the NCC correspond well to those in the Central Indian Tectonic Zone of IND. Moreover, the gravitational and magnetic anomalies in the Eastern Block of the NCC are quite similar to those in the Southern Block of IND, which shows that the NCC and IND might have been pieced together during the Paleoproterozoic. The geophysical result that verifies the correlation between the NCC and IND based on gravity and magnetic fields provides the evidence for Paleoproterozoic plate reconstruction and constrains the assembling patterns between the NCC and the IND.
