When CNA spoke to the siblings on WhatsApp, they were travelling north to Cappadocia by car, hoping to get to Istanbul next to catch an earlier flight back to Singapore.
The siblings were scheduled to fly home on Wednesday but are now looking to bring forward their Turkish Airlines flight to Monday.
They felt aftershocks during the journey to Cappadocia which would take them a total of seven hours – two hours from Sanliurfa to Gaziantep and another five hours from there to Cappadocia.
“It’s like we are so scared of feeling scared,” Mr Tajjlee said in an Instagram Story. “But we are content and pray we’ll make it safe(ly) to Cappadocia.”
Recalling the scene of the disaster, Ms Sriwayuni, 29, said she felt sad seeing the elderly and children crying for help.
The situation in Sanliurfa was “pretty chaotic” with “ambulances everywhere”, added Mr Tajjlee.
He said mosques in the city had collapsed and that authorities there were trying to evacuate people from the collapsed buildings.
“Mentally, it’s a lot to take in,” he said.
The siblings added that they are very thankful to their driver and tour guide for keeping them safe.
