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 CO2 gases stored in magma,and a series of positive feedback effects,the Tohoku-oki earthquake may result in an increase in the activ-ity of these volcanoes.Attention should be paid to potential triggering of volcanic eruptions by stress changes induced by the Tohoku-oki earthquake.展开更多

Various parameters of air temperatures on Mt Fuji in Japan were obtained from Japan Metrological Agency. Parameters of air temperatures were positively correlated with years on Mt. Fuji. In addition, the number of days under –24°C in January was negatively correlated with years. Global warming was also proved on Mt. Fuji in Japan, especially in winter. Therefore, we need to deal with global warming effect.展开更多
