In June and July 2018, a widely publicised cave rescue successfully extricated members of a junior football team trapped in Tham Luang Nang Non cave in Chiang Rai Province, Thailand. Twelve members of the team, aged eleven to seventeen, and their 25-year-old assistant coach entered the cave on 23 June after football practice. Shortly afterwards, heavy rains partially flooded the cave, trapping the group inside.
Efforts to locate the group were hampered by rising water levels and strong currents, and no contact was made for more than a week. The rescue effort expanded into a massive operation amid intense worldwide public interest. On 2 July, after advancing through narrow passages and muddy waters, British divers John Volanthen and Richard Stanton found the group alive on an elevated rock about 4 kilometres (2.5 mi) from the cave mouth. Rescue organisers discussed various options for extracting the group, including whether to teach them basic diving skills to enable their early rescue, wait until a new entrance was found or drilled, or wait for the floodwaters to subside at the end of the monsoon season months later. After days of pumping water from the cave system and a respite from rain, the rescue teams hastened to get everyone out before the next monsoon rain, which was expected to bring a potential 52 mm (2.0 in) of additional rainfall and was predicted to start around 11 July. Between 8 and 10 July, all of the boys and their coach were rescued from the cave by an international team.
The rescue effort involved more than 10,000 people, including over 100 divers, many rescue workers, representatives from about 100 governmental agencies, 900 police officers and 2,000 soldiers, and required ten police helicopters, seven police ambulances, more than 700 diving cylinders, and the pumping of more than a billion litres of water out of the caves.
There was one fatality, Saman Kunan, a 37-year-old former Thai Navy SEAL who died of asphyxiation on 6 July while returning to a staging base in the cave after delivering supplies of air.
