Some 3218 people have been killed in the 7.9 magnitude quake, which hit Nepal on Saturday.
It is Nepal’s worst quake since 1934 when 8 500 people died.
Nepal’s record of earthquakes dates to at least the 13th century, with significant temblors striking every 75 years.
The quake struck the heavily populated Katmandu Valley, near the capital and it was felt as far as Tibet, Bangladesh and India.
Five South Africans who had been reported missing in the quake have meanwhile been found.
It is also been reported that a group of eight Pretoria schoolgirls visiting the country, were unharmed and accounted for.
