World's largest cave revealed by 3D film crew

   

 

A team of seven Japanese film makers, with three cave explorers from the British Cave Research Association, on May 9 started work on a 3D documentary on the world's largest cave in Phong Nha-Ke Bang National Park in the central province of Quang Binh , Vietnam .

 

It is the first time a scientific film about cave was made  in 3D techniques.

 

Luu Minh Thanh, director of the park's managing board said , the documentary will offer researchers a better chance at understanding the origins of the cave, known locally as Son Doong, the forests and the fast flowing underground river inside. He added that the film would be broadcast in 160 countries and territories across the globe.

The cave, feared by locals for the whistling sound its underground river makes, was first discovered by a local man named Ho Khanh in 1991. In 2009, a group of British scientists from the British Cave Research Association, led by Howard Limbert, conducted a survey in Phong Nha-Ke Bang. The film will be televised world wide ( 160 countries and territories )  by the end of 2011.

 

According to Limbert, the cave is five times larger than the nearby Phong Nha cave, previously considered to be the largest cave in Vietnam . The largest chamber in Son Doong is over 5km in length, 200m in height and 150m in width.

 

Phong Nha-Ke Bang National Park was first recognized as a world natural heritage site by UNESCO in 2003 for its geological value. In July this year, the United Nations cultural organ plans to further honor the park a second time round for its biodiversity.
