Mt. Baekdu, the symbolically charged volcano straddling North Korea and China, could erupt again soon, a study warns.
Professor Yoon Sung-hyo of Pusan National University says there are indications that the volcano, though quiet for decades, could erupt any time and urged closer monitoring of the situation.
He says the concentration of helium in the volcano has been rising over the last decade or so, and magma levels are creeping up.
Yoon has been warning of another eruption since 2010, the first Korean to add his voice to a growing chorus of regional seismologists.
