Seismologists in China are paying some extra attention to North Korea's most iconic mountain.
Local media reports say China's Jilin Province will step up monitoring of volcanic activity at Mount Baekdu, known in China as Changbai Mountain, which straddles the border between the two countries.
Seismologists say Jilin is prone to volcanic activity because it's located on the edges of the Pacific and Eurasia Plates.
A powerful five-point-eight magnitude quake shook Jilin in late 2013, followed by at least five aftershocks which destroyed many homes and buildings.
Mount Baekdu is the largest active volcano in all of China --- but it has not erupted on a major scale in one-thosand years.
