Abstract

The 2011 Tohoku mega-thrust earthquake caused huge crustal deformation over a wide are of Mainland Japan. Many mega-thrust earthquakes worldwide have triggered volcanic eruptions nearby, and it is assumed that stress changes due to the Tohoku earthquake resulted in a perturbation to the magma system. The objectives of our study is to evaluate this perturbation quantitatively and to analyze the mechanism of the interaction between mega-thrust earthquakes and volcanic eruptions. This paper focuses on quasi-static stress change due to viscous relaxation of a source region and the surrounding area.
