'My nerves are shot for the time being'
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."
More than 1,000 injured

'It felt like a gentle rocking motion as if on a boat'
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."
Sleeping outside

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.
'I can't believe there's been another big one'
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."

Building shelters

People in Kathmandu, who are afraid to go back inside buildings, are trying to build makeshift shelters.
Operating when quake hit
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.
Exams moved outdoors

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.
'Duck, cover and hold'
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.

Delhi aftershocks 'horrendous'
Email: haveyoursay@bbc.co.uk
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.
Death toll increases

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."

'Another three nights under the open sky'
Email: haveyoursay@bbc.co.uk
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.
'Psychological damage'
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."
'The screaming of the people frightened me'
Email: haveyoursay@bbc.co.uk
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.

'More anxiety and fear'
Email: haveyoursay@bbc.co.uk
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...
Concern for children
ReutersCopyright: Reuters
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."
Impact in Tibet
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.
Death toll
Nepal's Information Minister Minendra Rijal tells the BBC that 16 people have died and 846 people have been injured in Tuesday's earthquake.

In neighbouring India, at least five people have been killed, Reuters news agency reports.
'We ran outside our house'
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."
Six major aftershocks
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.
'Felt in Pakistan'
Email: haveyoursay@bbc.co.uk
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.
Emotional toll
ReutersCopyright: Reuters
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.
'We're now experiencing an aftershock'
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."

'Hopefully this will bring out the best in all Nepalese'
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."
'It's happening again'

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.

The earthquake was felt in the Indian capital. Shaking of nearly half a minute sent people panicking onto the streets in Nepal.

BBC Science Correspondent
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.
Exams moved outdoors
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.
'Duck, cover and hold'
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.

Delhi aftershocks 'horrendous'
Email: haveyoursay@bbc.co.uk
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.

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."

'Another three nights under the open sky'
Email: haveyoursay@bbc.co.uk
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.
'Psychological damage'
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."
'The screaming of the people frightened me'
Email: haveyoursay@bbc.co.uk
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.

'More anxiety and fear'
Email: haveyoursay@bbc.co.uk
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...
Concern for children
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."
Impact in Tibet
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.
Death toll

'We ran outside our house'
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."
Six major aftershocks
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.

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."

The earthquake was felt in the Indian capital. Shaking of nearly half a minute sent people panicking onto the streets in Nepal. The epicentre of this quake is much closer to Everest, but the previous quake brought the climbing season to a close so at least, for the time being, there are no trekkers.
