This study is performed to find out the eruptive events of the historical period recorded in literature, which have been recognized and regarded as ones from Mt. Baekdusan, and to make volcanological interpretations of the eruptive events. Since the Millennium eruption, more than 31 eruptive events have been discovered, most of which are Plinian eruptions with volcanic ash that dispersed into the regions in the vicinity of the volcano. The 1903 record includes the event of the phreatomagmatic or vulcanian eruption that occurred within the Cheonji caldera lake. Based on the eruption records of the historical period and the 2002 precursor unrest to volcanic eruptions, Mt. Baekdusan has been evaluated and regarded as an active volcano that has the potential to erupt in the future.

In this research, we have extracted historical records regarding the geotechnology from the Goryeosa and the Annals of the Joseon Dynasty which are rated as ancient books that have objective views in the Goryeo Dynasty and the Joseon Dynasty in order to understand the national awareness and the social situation of the past events. We used the Korean history database system of National Institute of Korean History (NIKH) and collected related records by searching specific keywords such as volcano, mining, hot spring, and meteorite. According to the historical records, geological events such as the volcano and meteorite were regarded as important issues which were enough to be recorded in annals and surveyed by the dispatched government officials to the fields of events. In case of the hot springs, government officials conducted explorations of hot springs at king's orders and developed the potential areas of hot springs. Among the historical records on mining, the contents of geotechnology including the contents about discovered minerals and its locations can be easily found from those ancient books. Especially, it is possible to understand the history of geotechnology such as an establishment of modern organizations and a capitalistic flow for development through the history of the mining in the late Joseon Dynasty.

We assumed the situation where an eruption column had been formed by the explosive Plinian eruption from Mt. Baekdu and that the collapse of eruption column had caused pyroclastic density currents to occur. Based on this assumption, we simulated by using a Titan2D model. To find out about the range of the impacts of pyroclastic density currents by volcanic eruption scenarios, we studied the distance for the range of the impacts by VEIs. To compare the results by each volcanic eruption scenario, we set the location of the vent on the 8-direction flank of the outer rim and on the center of the caldera, the internal friction angle of the pyroclastic density currents as 35 o , the bed friction angle as 16 o . We set the pile height of column collapse and the vent diameter with various VEIs. We properly assumed the height of the column collapse, the diameter of the vent, the initial rates of the column collapse and the simulation period, based on the VEIs, gravity and the volume of the collapsed volcanic ash. According to the comparative analysis of the simulation results based on the increase of the eruption, the higher VEI by the increase of eruption products, the farther the pyroclastic density currents disperse. To the northwest from the vent on the northeast slope of the outer rim of the caldera, the impact range was 3.3 km, 4.6 km, 13.2 km, 24.0 km, 50.2 km, 83.4 km or more from VEI=2 to VEI=7, respectively. Once the database has been fully constructed, it can be used as a very important material in terms of disaster prevention and emergency management, which aim to minimize human and material damages in the vicinity of Mt. Baekdu when its eruption causes the pyroclastic density currents to occur.
