South Korea on Wednesday proposed holding a second round of talks with the Democratic People's Republic of Korea (DPRK) next week over a joint research into volcanic activities at the highest mountain on the Korean peninsula.

South Korean delegates to the talks sent a message to DPRK counterparts earlier in the day, suggesting they meet again in the DPRK border town of Kaesong next Tuesday to discuss a possibility of volcanic eruptions of Mount Paekdu, according to the unification ministry in Seoul.

"(South Korea) will prepare for a meeting that would allow more in-depth discussions," ministry spokeswoman Lee Jong-ju told reporters in a briefing.

The previous round of volcano talks, proposed by Pyongyang, brought together experts from both sides of the border in the South Korean border city of Munsan late last month amid rising concern following the devastating earthquake and tsunami that ravaged neighboring Japan.

The 2,740-meter mountain, which sits on the DPRK border with China, last erupted in 1903 and has since been inactive, but experts have warned it might have an active core and a potential eruption would create a greater chaos than the Icelandic volcanic eruption last year.
