Mt Paektu, which straddles the borders of North Korea and China, is responsible for one of the most catastrophic eruptions in human history, and scientists fear it could blow again.
Officials in China have closed a national park near to the volcano to prevent the public approaching Mt Paektu due to fears it could erupt at any moment.
Nuclear tests from the rogue nation of North Korea have triggered small tremors in the 70-square-mile Changbaishan National Nature Reserve – next to the volcano – prompting fears it could blow which led officials to close the park.
Chinese authorities said: “For the safety and convenience of travellers, we have temporarily closed the southern tourist zone of Changbai Mountain.
“Officials are thoroughly investigating the safety of the tourist area.
“The area will remain closed to the public until the potential risks disappear.”
Mount Paektu once underwent one of the most devastating eruptions in history in 946AD when it erupted so powerfully that it formed a five kilometre caldera at its summit and produced enough ash it even showered Japan – almost 680 miles (1,100km) away.
A team of scientists from South Korea previously warned nuclear tests from Kim Jong-Un’s nation could trigger an eruption.
The volcano, which stands at 9,000 feet tall, has not erupted since 1903, and an explosion is overdue.
The team, led by Hong Tae-kyung, a professor in the Department of Earth System Sciences at Yonsei University, examines the impact nuclear testing has on seismic activity.
The team looked at North Korea’s first three nuclear tests – in 2006, 2009, and 2013 – and found that any earthquake magnitude over 7.0 could cause a devastating eruption.
And the earthquakes are getting stronger with each nuclear test – its 2006 test triggered an earthquale with a magnitude of 3.6, 2009 saw an earthquake with a magnitude of 4.4, while 2013’s was 4.8.
Hong Tae-kyung said: “An underground nuclear explosion test near an active volcano constitutes a direct threat to the volcano.”
The report read: “North Korean nuclear explosions are expected to produce pressure changes of tens to hundreds of kilopascals, causing concern over the possible triggering of a volcanic eruption.”
