NEW DELHI: Two weeks after the devastating 7.8 magnitude earthquake in Nepal killed over 8000 people, another major earthquake with a magnitude of 7.3 struck near Mount Everest. At the time of writing, at least 68 people have been killed and over 1500 injured.

Across the border in Bihar, India another 15 people have been reported dead and over two dozen injured. One person in Uttar Pradesh has been reported dead. Tremors were also felt in Tibet, where one person has been reported dead, and Bangladesh.

The earthquake struck at 12:35 Nepali time (06:50 GMT) and was centred about 76km (47 miles) east of Kathmandu, in a rural area close to the Chinese border.

At the time of writing, the US reported that a Marine Corps helicopter involved in disaster relief efforts had gone missing. Eight people were on board. "Essentially what we have right now is truly a missing helicopter. We simply don't know its location," Pentagon spokesperson Col Steve Warren told Reuters.

Nepal has suffered hundreds of aftershocks since the devastating earthquake on April 25, with Tuesday’s earthquake being the largest yet. The country is still struggling to cope with devastating caused by the April quake, with relief and aid still to reach the far flung areas.

The mood in Nepal is captured by a series of photos posted on photo-sharing site Instagram. Some of the photos that were re-published by the Nepal Photo Project are being reproduced below.

Caption: Another quake – measuring more than 7 on the Richter scale – shook Nepal this afternoon. Although the casualties and destruction are smaller in number and scale I don’t have words to describe the sheer terror that has gripped people here.

After the scare of it all (and no doubt also a result of hurtling down 4 flights of stairs faster than I ever thought I could) my legs were a jelly mess for hours. There’s good jelly legs (the ones that come with that first kiss) and there are bad jelly legs. These were of the bad kind.

My colleagues were on the scene quickly – photos, news, tweets, info were at the touch of a button in a matter of seconds. And I’m glad they were. The world needs good journalists to do that. I physically saw how the access to information calmed people down (me included… thank you Twitter). But me: I just couldn’t take photos for some reason. I didn’t know where to start. So, for more than an hour, I did what the rest of the people around me did. I found a slither of shade and sat down. I used my phone while my battery lasted. I spoke to my family and told them I was fine.

Hours later I returned to Tundikhel – the park in the center of town. Over the past 2 weeks the number of people staying in tents here have dwindled as people have slowly gone back to the normalcy of life in the capital. Tonight the numbers here swelled again, as terrified people chose to rather sleep outside and out of harms way. Physical harm, that is. Psychological harm, well that’s another thing altogether… Photo by @samreinders

Caption: "People here in Nepal are shaken after yet another quake. Life had slowly started coming back to normal and nowseems like we are back to square one again. But the disaster response from both the government and the public has been balanced and calculated this time around. There is electricity and internet(thankfully), however people are opting to stay outdoors. Seen in the picture is a person carrying sleeping mats, blankets and other essentials to the makeshift tent for the night." Photo by @aerawbic

Caption: // in maharajganj, everyone is back out once again. when we met them this evening, they were setting up tents for the night. Shanti, the young girl in the mask told us that there is no way she was going to go back inside. their apartments were already severely cracked, & even the slightest tremor could now result in a total collapse -- Photo by Surabhi Tandon @ihbarus

Caption: A four-storey house collapsed during today's quake at Samakhushi, Kathmandu. The house was vacant after the massive quake of April 25 but locals suspects there might be few people trapped under it, as it fell on a small cyber-cafe beside it. Army personnel were trying to do the rescue operation without any light and proper equipment.

Within few weeks, we can again sense the feeling of fear in Kathmandu. People are scared to enter their own home and sleep in their own beds. Kathmandu has turned into a ghost town. Photo by @kishorksg

Caption: I was in Ranjana Galli ordering some soda, when all of a sudden, the earthquake hit and I headed towards Bhugolpark. On the way, I saw a cloud of dust rise above Basantpur. This photo was taken amidst all that fleeing. Photo by @backyard_nation

Caption: People are trapped with fear. Even more than the quake it's the psychological impact that's difficult to overcome right now. The past week had calmed the situation and life was returning to normalcy. But with today's big quake Fear of another quake or tremor occurring, has yet again stranded people out of their homes.
