13 aftershocks keep Nepal on edge, toll in fresh quake rises to 76

Over a dozen aftershocks jolted Nepal on Wednesday, keeping people on edge a day after a powerful 7.3-magnitude earthquake killed 76 people in the Himalayan nation that had just begun to rebuild itself following the devastation from the temblor less than three weeks ago.

The fresh quake hit the hardest in remote mountainous districts in northeast of the capital city Kathmandu, bringing down buildings and triggering landslides that blocked roads to remote villages in several areas.

The death toll from Tuesday's earthquake has climbed to 76, while the number of injured reached 1,987, according to a Nepal police spokesperson.

Most of the casualties were reported in Dolakha district, northeast of Kathmandu. The toll was expected to further rise.

Rescue workers are searching for survivors from the latest quake. Search is also on for a United States military helicopter that was reported missing with six Marines and two Nepalese soldiers on board while delivering aid.

Security personnel rescued nine Nepalese, an American man and a Korean woman on Wednesday, airlifting them through a helicopter from Dolakha.

Police said 32 of 75 districts were affected and several houses collapsed due to the fresh quake that was centred some 83 km east of Kathmandu near Mount Everest at a shallow depth of 15 kilometres.

As many as 13 aftershocks were reported on Tuesday, most of them centred around Dolakha and Sindhupalchowk, according to the Nepal Seismological Centre.

Tuesday's temblor was followed by a 6.3-magnitude aftershock 30 minutes later. A total of 33 aftershocks struck on Tuesday and continued into this morning.

Thousands of fear-stricken people spent the night in the open under plastic tents barely shielding them from cold.

The quake triggered massive panic among the people, who have been staying in the open since the 7.9-magnitude lethal temblor struck on April 25, killing over 8,000 people and flattening thousands of buildings besides destroying entire villages.

Officials walked through streets in quake-hit areas and asked people to leave the damaged buildings. Authorities have ordered all schools to be closed for the next two weeks.

Tuesday's quake had its impact in several Indian cities -- Bihar, West Bengal and Uttar Pradesh and tremors were felt across vast stretches of east and northeast India. The tremors were also felt in China, where one woman was killed in Tibet.
