Some 216 Thai tourists have emerged safely from Mount Rinjani National Park on the Indonesian island of Lombok near Bali after it was struck by a 6.4-magnitude temblor on Sunday morning, the Ministry of Foreign Affairs said on Monday.
The earthquake has killed at least 16 people and caused landslides but no Thais were reported harmed, according to reports.
Thai ambassador to Indonesia Songphol Sukchan said the Thai tourists made it to the Sembalun Lawang foothills and were then escorted to temporary accommodation provided by the Thai government.
All were reported to be in good heath. Thirty-six of them were due to fly home today via Kuala Lumpur while the others wait for their flights to be rescheduled.
Mr Songphol said Jakarta has assisted the stranded tourists, with Indonesian President Joko Widodo administering the mission himself.
One military officer told Indonesia TV that by late Monday afternoon more than 250 people had reached a relief post in Sembalun village and a team of rescuers had reached hundreds more near the mountain's crater lake.
He said some suffered light injuries and were traumatised but most were in good condition.
The National Disaster Mitigation Agency said more than 680 people had been stranded on Rinjani, an active volcano, based on figures from its entry gates where the visitors are registered. Most were foreign, coming from 26 countries including over 330 from Thailand.
Royal Thai Air Force commander-in-chief ACM Johm Rungswang said the air force was ready to send its planes to bring the stranded Thais back to Thailand should the Ministry of Foreign Affairs request that.
ACM Johm said Defence and Air Attache Group Capt Prapas Sornchaidee, who accompanied the Thai ambassador to Indonesia to the site at Mount Lombok, stated there were about 311 Thais stranded in the area.
Rescuers from the Indonesia's National Disaster Management Authority were dispatched to rescue and evacuate tourists from the mountain, with helicopters to be deployed to carry food and supplies to the area.
Injured tourists were to be evacuated first, according to ACM Johm.
He said an Indonesian search-and-rescue team was scouring the area on foot but was still several hours away. Another 150 members of the country's elite special forces have been deployed to assist.
About 200 Thais became stranded around Lake Segara Anak on Sunday due to landslides, with more recorded visiting other parts of the national park that same day.
Some, like Supaporn Bangmoung and Nupa Waen, confirmed they had been safely extracted on Facebook.
