地震・テクトニクスの研究を行っているポスドク研究員です。地殻ダイナミクス、プレートテクトニクス、地形形成、応力場形成等に興味があり、「日本列島東西圧縮の物理メカニズムの解明」の研究を遂行中です。(現在療養中)
I'm a postdoctoral researcher about Tectonophysics.
Our manuscript has been published in PEPS!
This study revealed the mechanism of the stress change from compression to extension in the forearc before and after the 2011 Tohoku earthquake.
Magnitude of the frictional stress at plate interface is 5-15 MPa.
