• This finding could contribute to a seismic hazard map of the eastern Himalaya, which can facilitate construction and planning in the region.
• Historical archives refer to often recurring earthquakes along the Eastern Himalaya for which geological evidence is lacking, raising the question of whether these events ruptured the surface or                     remained blind and how they contribute to the                   seismic budget of the region, which is home to                 millions of inhabitants.
• The study of the earthquake at Sadiya standing on a grassy plain, almost surrounded by forested Eastern Himalayas on the right bank of Lohit River, adds an important site to the seismic hazard assessment of the eastern Himalaya, which will benefit the inhabitants and help in providing better infrastructure across the Eastern Himalayan foothills which is one of the most densely populated regions in the world.
