The earthquakes sent terrified residents running onto the streets in Nepal's capital, Kathmandu, from buildings already damaged in the massive 7.9 magnitude earthquake that had struck three weeks ago killing more than 8000 people.
Prime Minister Narendra Modi held a meeting with top officials to review the situation. His office then tweeted his instructions.
An Indian Air Force MI-17 helicopter stationed in Kathmandu was sent to assess damage at Namche Bazaar, close to Mount Everest and 68 kilometres from the epicenter of the first quake.
Medics and volunteers formed a human chain at a Kathmandu hospital to keep a path open for ambulances.
Like April's earthquake, today's was shallow - 15 km deep. Shallow quakes are more deadly because the amount of energy released is focused over a smaller area.
