Day 9! An expert of a Thai youth football team trapped in a cave evaluates the possibility of survival.

　　　　　　 CCTV News:On July 1, local time, the search entered the ninth day. There is still no news of the missing persons. However, the weather in Thailand improved for three consecutive days, and rescuers took various measures and search and rescue efforts, which made the rescue work progress.　　

Rescue site

　　　　　　 At present, the water level in the cave has decreased compared with before, and the oxygen content in the cave should also be at a normal level. Rescuers have entered the third cave, which is about 3 kilometers away from the possible location of the missing person. Yin Narongsa, the government of Chiang Rai, said that if the local weather conditions continue to be good, it will be conducive to the progress of the rescue operation.

　　　　　　 However, geological experts from the Wildlife and Plant Protection Committee of Thailand National Park found that water from a small river outside the cave flowed into the cave, and measures are being taken to stop the river from flowing into the cave.

　　　　　　 Time goes by little by little, and the most worrying thing is whether the missing football team can "survive". Let’s find out what happened in the form of question and answer. What are the chances of these children surviving?

　　　　　　 Question 1: What happened?

　　　　　　 Twelve young soccer players and a coach in Thailand disappeared after "exploring" in a cave in a national park on June 23. Many rescue teams in Thailand and abroad continued to work for days, and still have no results.

　　　　　　 This cave, with a total length of over 10 kilometers, is the fourth longest cave in Thailand. Due to the complicated terrain in the cave, no one has completed the whole journey so far. Since the disappearance of 13 people, many areas in the cave have been flooded by rain, and silt has accumulated in the water, which has made the search and rescue work very difficult.

　　　　　　 Question 2: How many people are involved in the rescue at present?

　　　　　　 It is understood that Thailand has sent at least 1,000 rescuers to carry out search and rescue around the clock; In addition, China, Britain, the United States, Australia, Myanmar, Laos and other countries have sent cave exploration experts and rescue teams to support this operation. China cave rescue experts who have arrived in Thailand said that they have brought underwater robots, diving equipment, 3D imagers, etc., and will help Thailand to search and rescue the lost people through multi-pronged methods such as cave diving, shaft exploration, joint drilling and aviation rescue.

　　　　　　 Question 3: What is the current search and rescue plan?

　　　　　　 According to Yin Narongsa, the government of Chiang Rai, who is in command of the rescue front line, several search and rescue schemes are being carried out at the same time, including pumping rainwater out of the cave with a high-pressure pump, drilling holes at the end of the cave and on the rock wall, sending the search and rescue personnel into the cave from the shaft surveyed above the mountain, and sending frogmen to search for the missing persons. These schemes mainly focus on pumping water. At present, dozens of water pumps have been added in the local area to step up the drainage of floods in the cave while it does not rain. At the same time, rescuers sent a voice to the cave and threw packages containing food, water and mobile phones into the cave, hoping to let the lost people know that the rescue has been going on.

　　　　　　 Question 4: How likely are the trapped people to survive?

　　　　　　 Some cave experts believe that the football team with players aged between 11 and 16 and its 25-year-old coach have better physical fitness than ordinary people. It is reported that they are not exploring the cave for the first time, and they have a certain understanding of the terrain of the cave, and they should carry food with them. When food is exhausted and there is water, people can survive for two weeks at most, so they still have the possibility of survival.

　　　　　　 However, experts pointed out that the limestone at the top of the cave drips more water in the rainy season, and the water level in some areas of the cave is as high as 7 meters, so the clothes of the trapped people are likely to get wet. In addition, the temperature in the cave is low, and being trapped in the claustrophobic space for a long time leads to psychological changes. Their situation is still dangerous and rescue is urgent.
