The 7.3- magnitude quake with the epicentre in Dolakha district, some 130 km east of Kathmandu, caused heavy human loss as well as infrastructure damage, Xinhua news agency reported.
Most of the partially damaged buildings from the devastating April 25 temblor, including houses, government offices and schools, have been badly destroyed by the latest quake.
Over 8,200 people were killed in a massive 7.9-magnitude quake on April 25 and some 17,000 were injured.
Nepal Army, Nepal Police and Armed Police Force along with rescue teams from different countries have been deployed for the rescue operation in such worst-hit districts as Kavre, Sindhupalchowk, Rasuwa and Nuwakot.
However, landslides triggered by the earthquake have obstructed roads and relief distribution in parts of the Himalayan country.
