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.

“…Using an ellipsoid point source model and GPS and leveling data as constraints, Zhu et al [5] estimated the magma source at a depth of ~10 km. Studies of the magma evolution history of Tianchi volcano by Liu et al [6] revealed that there might be two magma chambers located in crust and mantle respectively.…”

“…Although the GPS and leveling data recorded from 2003 to 2005 indicated that the deformation activity in this region was decreasing, deep seated uplift and expansional deformation and shallow magmatism in the volcanic region were still detected [20]. Some studies suggested that the crustal magma chamber beneath the Tianchi volcano is composed of trachyte and pantellerite [6]. The volumetric expansion caused by the 2011 Tohoku-oki earthquake may lead to exsolution of H 2 O there, which in turn may increase the viscosity of magma and limit the ability of the magma to be uplifted.…”

“…The volumetric expansion caused by the 2011 Tohoku-oki earthquake may lead to exsolution of H 2 O there, which in turn may increase the viscosity of magma and limit the ability of the magma to be uplifted. However, the mantle magma chamber beneath the Tianchi volcano mainly has an alkaline basalt composition [6]. Volumetric expansion there again may lead to the exsolution of CO 2 , which in this case decreases the density and viscosity of the magma and promotes its ascent and depressurization.…”

Two days after the March 11, 2011, M w 9.0 Tohoku-oki earthquake, Shinmoedake volcano, located on the Japanese island of Honshu, erupted. Was this eruption triggered by the Tohoku-oki earthquake? Could Mount Fuji and Changbaishan volcanoes also be triggered to erupt? By calculating changes in the regional stress-strain field that resulted from the earthquake, we find that Mount Fuji, Shinmoedake and Changbaishan volcanoes are all located in regions of volumetric expansion. The volumetric expansions at a depth of 10 km are up to ~220 nano-strain, ~8 nano-strain, and ~14 nano-strain, respectively, for the three volcanoes. The strain changes inferred from GPS co-seismic displacements also suggest that these three volcanoes are located in regions with surface areal expansion. Considering that the expansional stress may cause the opening of magma channels, exsolution of CO 2 gases stored in magma, and a series of positive feedback effects, the Tohoku-oki earthquake may result in an increase in the activity of these volcanoes. Attention should be paid to potential triggering of volcanic eruptions by stress changes induced by the Tohoku-oki earthquake.2011 Tohoku-oki earthquake, Mount Fuji, Shinmoedake, Changbaishan, volumetric expansion, volcanic activities Citation:

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
