In Korea, it has been recognized as a relatively safe area for the volcanic ash, but the opinions of scholars and academics who are raising the risk of the explosion in Mt. The volcanic topography of Korea is believed to have been formed by volcanic activity from the end of the third to the fourth era of the Cenozoic era. The area around the Kauma Plateau extending to Mt. Paektu and the Lava Plateau of Yeonryeong-dong and Jeju Island, Ulleungdo, .

A study by the German volcanologist Dr. Hans Olihshin Minke, a team of German volcanologists, investigated the geology of Mt. Paektu under the permission of the North Korean authorities. In 1996, the Mt. Paektu erupted in 969 AD. It has argued that it would have had a considerable impact on the Earth's climate by reaching the East Sea, which is more than 1000 km away from Hamkyeong Island, to the northeast of Japan and Hokkaido, by raising the 96 billionth eruption to 25 kilometers above the stratosphere.

At the same time, the Chinese Academy of Science Academy of Guizhou Province estimated that about 200 million tons of hydrogen fluoride and 23 million tons of sulfur dioxide came together to cause the asphyxiation of the wild animals and livestock, the acid rain, and the destruction of the stratospheric ozone layer. In addition, there are volcanic ash and turbulent turbulence as fatal disasters, and Baekdusan volcanic ash accumulation is measured to be 3-83 m thick over a 35 km radius from the crater.

It has been observed that 10 ~ 15 times of eruptions have occurred since the massive eruption in the 900s, and the eruption activity has been actively resumed since 2002, and 10 ~ 15 times of earthquakes have been observed every month.

Paektu within 20 years due to the Great East Japan Earthquake on March 11, 2011 was reported to the Society. In Korea, A study on the Baekdusan volcano eruption simulation centered on the Baekdusan volcanic eruption simulation study revealed that the volcanic ash covered Ulleungdo 8 hours after the explosion and entered the Japanese Islands 12 hours later, causing serious damage to Northeast Asian air navigation.
