The death toll has risen to 42, according to Nepalese officials.
It posted a of the deaths on Twitter.
The British Red Cross says, external at the charity's hospital in Sindhupalchowk, Nepal, the Norwegian team has reported "few fatalities and many casualties" from Tuesday's second earthquake.
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."

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."

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.
