Impact
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.
Upon impact, tens of thousands of residents evacuated their homes, and many areas suffered from communication and power outages. The strong shaking caused significant building collapse and mudslides;
at least 111 people were confirmed killed and hundreds sustained injuries by the effects of the earthquake. As the earthquake occurred during the monsoon season, heavy rain and landslides made rescue work increasingly difficult.

Northern India suffered the worst from the earthquake, with at least 75 people killed.
