Scientists from North and South Korea met on Tuesday to discuss a joint scientific survey of potential volcanic and seismic activity at the highest mountain on the Korean peninsula. Four scientists from each side met at the North Korean border town of Kaesong to discuss potential research at Mount Paekdu, located along North Korea's border with China. The 2,740-meter high mountain last erupted in 1903, but experts say recent scientific data suggest Paekdu has an active core that, if it erupts, could cause a huge lake to overflow and flood surrounding areas.
