The earthquake struck near a mountainous, albeit very populous region near the Sikkim–Nepal border; most of the structures were highly vulnerable to earthquake shaking.
India Northern India suffered the worst from the earthquake, with at least 75 people killed. Sixty people were reportedly killed in Sikkim alone. At least seven people died in
Bihar while six deaths have been reported in
West Bengal. Power supply was disrupted in areas near Sikkim, including
Kalimpong of
Darjeeling district, and adjoining
Jalpaiguri and
Cooch Behar districts; the outages were in part blamed on an affected
electric substation in
Siliguri. Water supply was interrupted in Sikkim.
National Highway 31, the major highway linking Sikkim to the rest of India, was damaged. In India, the total
property damage is estimated to be around $22.3 billion
USD, making it one of the costliest natural disasters in Indian history.
Sikkim Two buildings of the
Indo-Tibetan Border Police in the Pegong areas of
North Sikkim collapsed. In
Gangtok, many government offices and hospitals were left unusable. The heavy shaking destroyed the villages of Lingzya,
Sakyong, Pentong, Bay and Tholong.
Nepal In the capital city of Nepal,
Kathmandu, damage from the earthquake was comparatively limited. Three people were killed when a wall at the British Embassy collapsed, and many others suffered injuries. The shaking effects were more severe in eastern Nepal, closer to the epicenter. There, hundreds of homes sustained significant damage, and due to saturated soil from preceding heavy rains widespread mudslides impacted the region.
Sunsari experienced power and telephone communication outages. Two people were killed in the eastern city of
Dharan. Overall, in Nepal 6 people died due to the earthquake.

Dhaka,

Sylhet,
Mymensingh,
Barisal,
Faridpur,
Jessore,
Khulna,
Pabna,
Bogra,
Comilla,

Paro. There were also reports of a landslide right after crossing the Isuna Bridge from Paro towards
Thimphu, and falling boulders after crossing Chundzom Bridge. Citizens were asked to avoid traveling on the Paro-Thimphu highway. Telecommunications networks were disrupted, with cellular networks unavailable after the quake. Prime Minister of Bhutan
Jigmi Thinley updated in his status as "Phone lines remains clogged reflecting our caring and close knit society. No damage reported from East Bhutan. Four road blocks caused by falling debris are reported on the Chukha–Phuntsholing road. Two homes in Haa report damage with three to four people having suffered minor injury. Thimphu Dzong has sustained some cracks in the Utse and one of the four corner towers. Occupants have been moved out to safer parts.
