The Literature Publishing House introduced a photo book featuring Son Doong Cave in the central province of Quang Binh on March 19 at the General Sciences Library of Ho Chi Minh City.
The photo book is titled “Son Doong Cave - the Underground Paradise”. Ha Quoc Anh, the author, also made a Son Doong calendar earlier this year.
The book has two parts in both Vietnamese and English. It highlights the unique beauty of the cave and the author’s real experiences exploring it. Son Doong cave is world's largest cave, located in Quang Binh province, Viet Nam. It is found by a local man named Ho Khanh in 1991 and was recently discovered in 2009 by British cavers, led by Howard Limbert. The name "Son Doong" cave means "mountain river cave", It was created 2-5 million years ago by river water eroding away the limestone underneath the mountain Where the limestone was weak, the ceiling collapsed creating huge skylights...
The biggest section of Son Dong is five kilometers in length, 200 meters high and 150 meters wide, said Howard Limbert of the British Cave Research Association team searching the area April 10-14, 2009. Son Dong is much larger than Deer Cave in Malaysia, currently considered the world’s largest, an explorer said (Deer is 90 meters wide, 100 meters high and 2 kilometers long). The Son Doong cave has replaced to take pole position as the world’s largest cave.
