Real Lava Tubes: Jeju, a Volcanic Island in Korea! Go on a volcanic tour with me ㅎㅎ

Hello this is Korean Sister Do you know Jeju Island It is one of the most beautiful islands in South Korea or even in the world I was invited there Why Because it's one of the longest caves in the world the Manjang Cave How was the Manjang Cave formed The black hill exploded and as the magma flowed the cave was formed I will walk up and down the place where magma flowed a million years ago Four YouTubers were invited and I was the third one From here to the entrance of Manjang Cave We will walk about 8 kilometers As you have probably heard Manjanggul is an open area but the path I will walk today is Once a year and only for a few days it's an exclusive area that's not open to the public Let's take a look together with our eyes wide open Okay let's head to Jeju Island together Wow Oh the air is nice I received this natural clothing I changed into it and I am now ready to depart The path we are taking today is We pass through the three caves: Bokoreum Cave Dae Rimposal Cave and Manjang Cave It's not about going to the cave That's walking along the place where the cave was formed by flowing lava Shall we start These are places where lava has flowed This is our sacred mountain This rock has formed like this Hot lava is flowing and when it cools the surface hardens When hot lava flows out it creates a lava cave So this is the upper part of the cave This is a rope structure The lava is cooling as it flows over the surface The hot lava is flowing inside surging and churning It's called a rope structure because it looks like a twisted rope This is now a hotspot This is called a lava bridge Lava cave This was originally a cave here It's because the foundation is weak and it collapsed This is what remains now As you can see from the side the lava is flowing smoothly The place where the lava flowed Lava flows continuously like a river That place where it flowed is now hardened This is the lava flow that appears I walked through the area where lava had flowed It was really great It looks like there's a scene of flowing lava Now we'll go up and cross the lava cave We are now entering the Daelim Cave Daelim Cave Daelim Lava Tube This is an artwork It is an artwork This is the cave Wow It's a surprise He's a bad grandfather I can't go down I have to descend on the rope I go down making a "Uuuh" sound like Tarzan It might come out if you do a little We will climb up to the Manjanggul and then go through the lava tube Our Jeju Island had two types of lava flows One is "Pahoihoi" in Hawaiian One is "Aa" in Hawaiian This is the Hawaiian pronunciation But they decided to use this as a dinosaur by the world's seismologists This is the counterpart of the Pahoihoi lava field This lava has cooled on the surface That's where the hot lava escaped That's why the ground is exposed like this There is a cave below Teacher Bu Jongyu from Gyeongyeong Elementary School led the children in a little detective group for an investigation At that time starting from the first entrance searching for the second and third entrances since the entrances were already designated back then The investigation by Teacher Bujong was acknowledged among us and now this place has become the third entrance Then the middle one has two inlets and the bottom one has one inlet It seems even elementary students went there Yes Manjang Gull Cave Entrance 3 Oh wow really The leaves have fallen The depth is 15m 15m Then did the team leader go down here as well Yes you have to go along one line Wow that's cool It's nice to see you here 15 minutes It's great There are many rocks rocks This area is now all caves That's right Jeju Island is famous for three things Stone wind woman Right There aren't many women anymore Is that not the case anymore But there are really a lot of rocks rocks Wow You all we are passing through Gyeongjwa As the leader said A straight forest Zawal is a stone As you can see the place we are passing through is Are there many stones This is a mosquito A typical example of a long-tailed mosquito This is a typical ginkgo tree By looking at this tree you can see how a ginkgo tree grows This is not a root Why is there no root It's because of this stone it can't grow a root Oh like this parallel So it just stretches sideways when this tree grows to a certain extent and can no longer support itself Here he falls and dies but it's not the end for other trees grow and more trees grow and so on The forest is maintained but there are no trees of course That's the case The interesting thing about this place is tha This is a place with many stones Therefore this old tree grows like this Don't go down Because there's nowhere to go Still the trees are growing like this This is a small tree But life is still growing That's really amazing Wow I am moving along with the trees And I am moving towards the sea Oh you really look like a jungle explorer Here deer use these waters Wild animals use them and birds also use this water And this is The vine of the pod didn't look like it had split open So the vine of the pod is in the air Negative ions are produced in large quantities air circulates between the rocks as I mentioned earlier warm air in winter Cool air comes out in the summer That's why if you come in now it's a bit cooler than outside Why setups The temperature outside has risen a bit So if you put it here the cool air and When meeting this external air the air becomes weak Therefore in such areas some plants that usually don't grow sometimes do In the case of our black ginseng it is a plant that only grows in the high mountain valleys of Hallasan Black Oryong grows in areas that are only 300 meters high So even though the area is small Due to various vegetation distributions we refer to it as the restoration of the ecosystem This type of road is very common worldwide Therefore this place is significant for the global ecosystem The English name is Black Lava Tube The sunlight is visible I just came from Gochang It's really hot now Look at this sunlight Oh it's so hot I'm still walking along the ridge I'm looking for many trees along with fruits Wow we've almost arrived at Manjang Cave This is already Manjang Cave This is rock This is the cave below And this is the upper level of the cave I am climbing up the cave Here it says "cave " You are climbing up the cave This is the entrance to the cave The description of the Mangan Lava Tube is here The restoration of the 98th ecosystem This is one of the largest lava tubes in the world 18 meters in size and 23 meters in height I am today Born on the Black Hill the lava flow path third sectio We walked through the inside and outside of the cave path How about you Do you also see that scene in your mind of lava flowing a million years ago Keep following this path and eventually this lava will go all the way to the sea I'm also curious about the next path
