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."
