The latest earthquake hit near the town of Namche Bazar, near Mount Everest.
The US Geological Survey said it had a magnitude of 7.4. An earthquake on 25 April, centred in western Nepal, had a magnitude of 7.8.
The latest tremor was felt as far away as the Indian capital Delhi, as well as Dhaka, the capital of Bangladesh.
Strong tremors were felt in the capital of Nepal, Kathmandu, which was badly damaged in last month's earthquake.
"This is a really big one," Prakash Shilpakar, the owner of a craft shop in Kathmandu, told the Reuters news agency.
Reports said people rushed from buildings in Kathmandu as the quake struck at 12:35 local time (07:50 GMT).
The epicentre of the latest earthquake was 83km (52 miles) east of Kathmandu, in a rural area close to the Chinese border.
It struck at a depth of 18.5km (11.5 miles), according to the US Geological Survey.
CNN adds: A magnitude 7.4 earthquake struck Nepal on Tuesday, the U.S. Geological Survey said, less than three weeks after a quake devastated large areas of the Himalayan nation.
The earthquake Tuesday was centered in eastern Nepal, near the border with China, at a depth of about 18.5 kilometers (11.5 miles), the USGS said.
The magnitude 7.8 quake that hit Nepal on April 25 killed more than 8,000 people.
The epicenter of new earthquake was about 83 kilometers from Kathmandu, the Nepali capital where many buildings were destroyed in the earlier quake.
Manesh Shrestha, a CNN producer, was with a group of people helping to clear debris in a town outside Kathmandu when the new quake struck.
He said it caused damaged houses to start to collapse.
