“…[7] The volcanic history of Mount Paekdu can be divided into four stages based on age data, eruption style, and magma compositional changes [Wei et al, 2007], as follows (from the oldest to the youngest): (i) preshield plateau-forming eruptions, (ii) basalt shield formation, (iii) construction of a trachytic composite cone, and (iv) explosive ignimbriteforming eruptions. In the first stage, a fissure eruption produced the Maansan, Zeungbongsan, Naedusan, and Changbaeg basalts from the Oligocene to the Miocene (28-13 Ma) [Liu, 1983[Liu, , 1988.…”

“…At 3.11 Ma, alkali rhyolite erupted from Mount Hongdu near Mangcheona. The Kunhamsan and Bocheon basalts formed between 2.90 and 1.70 Ma, constructing a shield volcano in the area to the north and east of Mount Paekdu and in the area around Bocheon to the south of Mount Paekdu [Liu, 1983;Wei et al, 2007]. In the third stage, the trachytic composite volcano, with a diameter of 20-30 km and a height of 650 m, formed during the Pleistocene (0.61-0.09 Ma) [Liu, 1983;Liu et al, 1989].…”

[1] Here we use the global gravity field data set EGM2008 for 3-D crustal density modeling of the Mount Paekdu stratovolcano and surrounding area located on the border between North Korea and China. Curvature analysis and Euler deconvolution are used to assist interpretation, and the 3-D model is constrained by multiple geological and geophysical data sets. Mount Paekdu is characterized by a low Bouguer anomaly of À110 × 10 À5 m/s 2 , which is caused by the combined gravity effects of (1) a depth to the Moho of about 40 km, (2) a zone with lower P wave velocity and density than the surrounding, (3) low density volcanic rocks on the surface, and (4) the presence of a magma chamber that has not previously been identified. The modeled magma chamber has a mean thickness of 5 km and a density of about 2350 kg/m 3 and is located <10 km from the surface. Magma chambers are also modeled beneath Mount Wangtian and Mount Nampotae. However, the results of the 3-D density modeling do not confirm the existence of a previously proposed midcrustal low-velocity zone in the area 70 km to the north of Mount Paekdu. Since the Pliocene, volcanic activity in the Mount Paekdu region has migrated from the east coast of North Korea to the northwest, following the path of NW-SE trending faults.

“…It can range from relatively small "monogenetic" volcanic fields composed of a few dispersed smallvolume vents of mainly alkalic basaltic compositions, such as the Auckland Volcanic Field in New Zealand (McGee et al 2013), to large volcanic edifices consisting of evolved lavas ranging from phonolite to alkalic rhyolite, and capable of generating large caldera-forming eruptions, such as Changbaishan, China (Wei et al 2007). There exists a plethora of intermediate examples on a scale between these very different types of intraplate volcanoes.…”

that distinguish it from the rest of the system. Geochemical modelling indicates that magmatic differentiation through crystal fractionation and minor crustal assimilation occurred in crustal and shallow sub-volcanic magma reservoirs. In the central part of the system, a number of vertically spaced reservoirs acted as a filter, capturing basaltic dykes and hindering their ascent. In the outer region, dykes either reached the surface unhindered and erupted to form the basaltic/trachybasaltic succession or stalled at crustal levels and differentiated to trachyte before forming dispersed domes/flows. The central plumbing system "filter" resulted in a nest-shaped volcano, with a trachytic core surrounded by basaltic products, and stopped direct injection of basaltic magmas into the shallow syenitic magma reservoir, likely preventing its destabilization and explosive eruption.

Abstract:The Baegdusan Volcano which erupted violently at 1000 AD is still have possibility of eruption. Therefore, it is necessary to monitor regularly the possibility of eruption. However, it is very difficult to install regular monitoring system or to get regularly monitored data due to geopolitic problems. This is why we have to develop regular monitoring technique using satellite. The geoid in the Baegdusan Volcanic area calculated from gravity data obtained from GRACE satellite, decreased from 2002 to 2005. The period of decreasing is well matched with time when magma activities were recognized in the Baegdusan Volcanic area. The decrease in geoid is interpreted to be caused by the decrease of water storage. Considering that the amount of rainfall from 2002 and 2005 is almost constant, the decrease in geoid may be related to the magma activity under the Baegdusan Volcano. The geomagnetic total force in the Baegdusan Volcanic area measured by CHAMP satellite, decreased from 2000 to 2005 and increased after 2005. The period of decrease is well matched with the time with increased activity of magma chamber under the Baegdusan Volcano indicating that the decrease of geomagnetic total force is caused by demagnetization of surrounding rocks due to the increase of temperature of magma chamber. These data
