North Korea: Fresh test could trigger radioactive leak, South says

A fresh nuclear test at North Korea's mountainous testing site could trigger a leak of radioactive material, South Korea's chief meteorologist has warned.

A hollow space of up to 100m in length in the bottom of Mount Mantap could implode, Nam Jae-cheol said.
Pyongyang's last nuclear test in early September appeared to have triggered several landslides.

North Korea has conducted six nuclear tests since 2006, using the same site test each time.

"There is a hollow space, which measures about 60 to 100 metres in length, at the bottom of Mount Mantap in the Punggye-ri site," Mr Nam was quoted by South Korean news agency Yonhap as saying.
"Should another nuke test occur, there is the possibility of a collapse," he warned.
 

The Punggye-ri test site, situated in mountainous terrain in the north-east of the country, is thought to be Pyongyang's main nuclear facility and the only active nuclear testing site in the world.
