About the incident

  • After recent rainfalls, parts of the cave flooded and authorities feared that the group either drowned or was trapped inside the cave.
  • Thai Navy SEAL divers had been searching the caves ever since.
  • Owing to non-stop rain which further flooded the cave entrance, searches have been periodically interrupted.
  • Thai NAVYdivers soon got international help from American, Australian, British and Chinese divers, military members, and emergency personnel. 
  • The group was found alive after 10 days and all 12 boys along with their coach were reported alive.
  • They were found by British volunteer divers around 400 meters away from a spot nicknamed Pattaya Beach- an elevated mound in the cave.

About the Tham Luang Nang Noncave

  • The “Great Cave of the Sleeping Lady” (Tham Luang Nang Non) is located in the Chiang Rai province in northern Thailand.
  • It is a semi-dry limestone cavewhich is 10 kilometres (6.2 mi) long, and has many deep recesses, narrow passages and tunnels winding under hundreds of meters of limestone strata.
  • There are numerous stalactitesand stalagmites in some parts of the system.
  • The exact geography of this cave system is poorly known.

The science behind the cave

  • Water plays an important role in the formation of Thailand’s caves, but it is also by far the most dangerous element when exploring wild cave systems.
  • According to the geological map of Thailandthe Doi Nang Non mountain range is composed of a succession of sandstone, limestone, shale and chert.
  • Limestone is a sedimentary rock, vulnerable to tectonic deformation and erosion by water.
  • Water enters the mountain following superficial cracks and faults.
  • As limestone is dissolved by this groundwater, a three-dimensional network of caverns and conduits forms over time.
  • Such karstsystems act like a natural sponge inside the mountain.
  • During some days of good weather, the cave appears completely dry.
  • In fact, during the dry season (September-June), Tham Luang cave can be easily reached on foot.
