Second Nepal earthquake strikes
- A major earthquake has struck eastern Nepal, the second one in two weeks.
- The US Geological Survey says Tuesday's quake has a magnitude of 7.3.
- At least 29 people have been killed and 1,006 injured in Nepal, officials say.
- More than 8,000 people were killed in the first, devastating quake on 25 April.
The death toll has risen to 42, according to Nepalese officials.
It posted a of the deaths on Twitter.
Dr Kate Yarrow is a gynaecologist preparing to go to Nepal with charity Medecins Sans Frontieres:
"This morning our first fully trained doctor whom we sponsored, was flying with MSF via helicopter towards the Everest region to help those affected by the initial earthquake on April 25. Two minutes away from the designated landing area, they saw enormous landslides and buildings collapse beneath them."
More pictures are coming in of buildings which collapsed in Tuesday's earthquake.

James Oglethorpe and his family, originally from East Sussex, lives in Kathmandu: "The first one I was in the car, the second one outside and this one working at my desk which I got under. It felt as though a giant had hold of the house and shook and shook and shook it, everything shaking and swaying. The ground is still moving as though we are on jelly. My nerves are shot for the time being. Thankfully we are all safe.
"My son works for the UN and is walking home, my wife has been out but is coming home. We are putting up tents on the waste ground beside our house, which we did after the last one. We'll sleep out there tonight. Our house does look ok, in the local neighbourhood some walls are down and a six storey block of flats has major cracks. It is probably compounded damage since the last time."
Medics are pictured consoling themselves at a police hospital in Kathmandu. More than 1,000 people have been injured in the latest quake.
Richard Jones is in Kathmandu and experienced today's earthquake: "We are staying about 2km from the centre of Kathmandu. Today's earthquake was quite shallow compared to the major quake a few weeks ago. It felt like a gentle rocking motion as if on a boat. I had been at the Annapurna Base Camp when the bigger earthquake happened, 3,500 metres up in the mountains.
"This one felt a lot less dramatic and I didn't feel at any risk as we were in open space. It lasted 40 to 45 seconds as opposed to previous aftershocks that lasted around five to 10 seconds. There are modern buildings where we are with massive cracks in them - they look like they are ready to go."
Temporary shelter could be seen in Kathmandu from above on Tuesday, before the earthquake hit. The numbers sleeping outside are now expected to rise again.
Jessica Bloor from Shropshire, who works at the British School in Kathmandu, told the BBC: "Obviously we know what [earthquakes] feel like now. Luckily I was in an apartment which was well constructed and I just got under the coffee table and waited for it to be over.
"I've been into Kathmandu today and things seem to be a bit more normal now. There's people camping out still in the central park, but I can't quite believe there's been another big one."
Nepalese police are searching for victims after a house collapsed in the capital.
BBC News, Kathmandu
People in Kathmandu, who are afraid to go back inside buildings, are trying to build makeshift shelters.
Yuvraj Agrawal is an orthopaedic surgeon from Sheffield volunteering at a hospital in Dhulikhel near Kathmandu: "I was operating on a lady's foot from the earthquake on 25 April when all it started shaking. Instruments started to drop off the table... The patient, 23, lay under spinal anaesthetic, unable to move from her legs down. She remained calm without moving any muscle.
"She said: 'I'm thinking of my parents who survived the previous earthquake and are now living in a tent in Sindhupalchowk'. I couldn't leave my patient, so I stayed with her.
"We've been trying not to react to the multiple aftershocks since then. The hospital is very busy, we've had lots of patients come in but no lost lives. We have suspended planned operations and have five orthopaedic theatres running back to back. Since 25 April, things had slowly been getting back to normal, but this afternoon it has been non-stop."

The epicentre this time is about 80km (49 miles) east-north-east of Kathmandu, halfway to Everest. On 25 April, the big quake began 80km to the north-west of the capital. In April, we saw the fault boundary rupture eastwards for 150km (93 miles). And the immediate assessment suggests Tuesday's tremor has occurred right at the eastern edge of this failure.
In that sense, this second earthquake was almost certainly triggered by the stress changes caused by the first one. Indeed, the US Geological Survey had a forecast for an aftershock in this general area. Its modelling suggested there was 1-in-200 chance of a M7-7.8 event occurring this week.
Tremors from Tuesday's quake were felt as far afield as India. In this picture, college students in Siliguri, West Bengal state, are reported to be taking an exam outdoors.
Abinash, Biratnagar, Nepal: DUCK, COVER AND HOLD. I am an engineer by profession & shared the ways to be safe from earthquake with many fellows but at the moment when earthquake is felt, the panic created within everyone makes their mind nil. Nearby, I saw everyone running haphazardly shouting & crying on the way to my home.
Saurav Regmi took this photo in Basundhara, Kathmandu, and says: "Hospital workers were shifting patients to roadside temporary tents. After the Tuesday quake, it is not safe for anyone to stay inside the already cracked buildings."
Dev, Delhi, India: The aftershocks of the earthquake felt today at New Delhi were quite horrendous as people ran out of their high-rise buildings towards open spaces - though the potential damage caused by this current earthquake in New Delhi or parts of northern India were quite negligible. However, I feel grief-stricken thinking about the crisis that has fallen upon the innocent children and people of Nepal.
BBC News, Delhi
The Nepalese government tells the BBC the number of dead has risen to 29, with 1,006 injured. It says 31 of the 75 districts are affected.
British tourists Richard Jones and his friend, James Watson, were on the way to the immigration office in Kathmandu when the latest quake hit. "The taxi driver didn't have control of the steering as if he was being forced down a slalom course. We shouted at him to stop in an area that was safe. Getting out it felt like we were on a swaying boat. Roads were jammed and the local drivers behaving erratically. We ended up walking back across the city."
Sandesh Shrestha, Kathmandu, Nepal: And just when we thought the worst part was over, Mother Earth sought to crush our hopes. At first we thought it was another normal aftershock, but then it started shaking harder. Within seconds everyone was across the streets, away from the taller buildings. The water inside the "dhungedhara" (stone water tap) was shaking violently as well and the top of an old building, already cracked, went down. It seems we'll be spending another three nights under the open sky.
Former Nepal correspondent Charles Haviland said the earthquake will have caused "psychological damage".
"That sense of returning normality with aid being delivered to villages and people finding reasons for a bit of optimism, a bit of cheer in their lives, suddenly that sense of security I think will be knocked quite badly."
Shalav in Bouddha, Kathmandu: This was a real big one and I was having lunch with my co-workers when we all ran. It was the screaming of the people and the noise of the earth, building and windows shaking that frightened me the most. No casualties near my place though, I just hope the rest of my country is like that.
The United World Schools team messaged us on WhatsApp; they are currently searching for people trapped in collapsed buildings (like the one above) in the community of Baga, around 20km (12.5 miles) from the epicentre.
Roshan Kumar, Kathmandu, Nepal: It feels more new quakes are coming to us rather than only aftershocks. People are already terrified and this adds to more anxiety and fear. The buildings that'd cracked and loosened earlier are bound to fall and [I] have heard many houses have collapsed...
Kent Page from Unicef tells the BBC he was in a school in Kathmandu assessing damage when the quake hit. He said: "We thought the school was going to collapse. People were very, very scared. It was scary for me. I can't imagine what it's like for children who have now been through two earthquakes. We are very concerned about the children of Nepal."
The quake was felt very strongly in the Tibetan town of Zhangmu near the border with Nepal, Chinese state news agency Xinhua reports.
A police rescuer in the town told reporters he saw rocks rolling down the mountains, blocking roads. He also saw large landslides on the Nepalese side. So far there have been no reports of casualties in Tibet.
Nepal's Information Minister Minendra Rijal tells the BBC that 16 people have died and 846 people have been injured in Tuesday's earthquake.
Anukram Adhikary messaged the BBC to say: "The earth shook for what felt like eternity. All of my family and the neighbours are now all crammed up in our backyard, making fire to fend off mosquitoes."
At least 14 people have died in Nepal's latest quake - including five in Sindhupalchowk, the district to the east of Kathmandu that reported the most deaths in the 25 April earthquake, Nepalese officials say.
In neighbouring India, at least five people have been killed, Reuters news agency reports.
Jackson Subedi is an aid worker in Baluwatar, Kathmandu, Nepal: "We are safe but the earthquake this time was also dangerous. We could just run outside our house. I saw a nearby wall collapse and it injured one relative of ours. We don't know if this is an aftershock or another devastating quake."
There have been six large aftershocks in Nepal since the 7.3-magnitude struck. Six of them were magnitude 5.0 or higher, according to the US Geological Survey. One of them, 31 minutes after the first tremor, was of magnitude 6.3.
Aamir, Lahore, Pakistan: I was sitting in a Lahore office, and I felt shockwaves. I contacted a friend in Nepal and they told me, it is a 7.4 quake. On the news sites I have seen people... saying it is felt in Delhi, India, but it was also felt in Pakistan.
Nepalese people had been dealing with daily aftershocks since 25 April. Tuesday's 7.3-magnitude earthquake has taken a great emotional toll on already frightened residents.
Dr Nabin Sinjali is working at the hospital in Ramechhap, Nepal: "We're now experiencing an aftershock. The earthquake was very strong and we are now outside the hospital and are frightened.
"The hospital had been partially damaged in the earlier earthquake a few weeks ago; this damage has now increased. We are having to use a tent outside the hospital and have injured people coming here for treatment."
Student Rupak Raj Sunuwar sent us this message on WhatsApp: "We people living in Kathmandu Valley are living with fear and this earthquake has just increased it. We are on the 4th floor... Smaller aftershocks are also felt clearly at such height."
Before Tuesday's quake, Nepal had been returning to a semblance of normality, as the BBC's Justin Rowlatt reported, even though buildings were still listing and thousands were sleeping in tents and under tarpaulins in Kathmandu.
A WhatsApp user sent us this message: "Quakes tremors also felt in Rupandehi district of Bhairahawa area. But no one is hurt. Thanks to God we are safe."
Kashish Das Shrestha sent us this photo of the tents on the streets of Kathmandu.
Bibush Amatya, a post-grad doctor in Kathmandu, says: "This one was unexpected. We had resumed normal outpatient services at the dermatology department of Tribhuvan University, Teaching Hospital, Maharajganj. At the time, I was giving a presentation on skin biopsy techniques. The presentation was about to end when we were hit by tremors that lasted close to 25 seconds.
"All the inpatients went out in the open. There was crying and wailing all around. And comforting too. The scale of the damage in nearby multi-storied buildings and the Himalayan Bank, Maharajgunj branch, is obvious. We need to unite in this time of national crisis. Hopefully this will bring out the best in all Nepalese. When all is done and dusted, we Nepalese will rise again."
BBC News, Baluwa,
west of Kathmandu, reports: "We were in an open place surrounded by mountains. I heard a cry of 'It's happening again'.
"Rehabilitation has not really started yet. People are still living in temporary structures."
More than 300 people have been injured, according to Kathmandu police, Reuters news agency reports.
Olivia Lang, Kathmandu
There was a lot of panic when it struck. There have been several aftershocks recently but when people were standing outside, this time it kept on going.
It wasn't just a concern here, but a lot of people who work in Kathmandu have relatives in villages who have been hard hit by the previous earthquake.
Ashish Sharma, Kathmandu, Nepal: When the capital city started to return to its normal activity, the country shook again. It's making the life of the normal people and daily bread earners really hard.
Charlotte Panther, Viber.com, says: "Following the latest earthquake in Nepal, 'Viber Out' is free for Nepali users. This means that all domestic and international calls to mobile and landline numbers are free for the next 48 hours. We hope this will help those trying to reach friends and family in the region at this difficult time. We will continue to monitor the situation to provide the best help that we can."

Dr Nabin Sinjali from Ramechhap, Nepal, sent us a WhatsApp message: "I am a medical doctor working in one of the remote district of quake-hit areas of Nepal. I was examining an older patient during today's tremor when everyone in our hospital started to cry and ran out as soon as possible. We are outside now in open space. There are still small tremors. We are frightened!!!"
