New Perspective of Subduction Zone Earthquake

Edited by: Gaku Kimura, Juichiro Ashi, Masataka Kinoshita, Christie Rowe, David Shelly

The Japanese government (MEXT, Ministry of Education, Culture, Sports, Science and Technology) is supporting a project “new perspective of the great subduction zone earthquake from the super deep drilling” (named KANAME as an abbreviation of Kakenhi for Nankai Megathrust”) from 2009 through 2013.

The aim of the special issue is to outline the achievement of the KANAME project, to bring together some Integrated Ocean Drilling Program (IODP) drilling findings and their related research, and to increase understanding of major earthquakes and tsunami at subduction zones.

    Estimation of slip rate and fault displacement during shallow earthquake rupture in the Nankai subduction zone

    Enormous earthquakes repeatedly occur in subduction zones, and the slips along megathrusts, in particular those propagating to the toe of the forearc wedge, generate ruinous tsunamis. Quantitative evaluation o...

    Friction properties of the plate boundary megathrust beneath the frontal wedge near the Japan Trench: an inference from topographic variation

    The 2011 Tohoku-Oki earthquake (Mw 9.0) produced a fault rupture that extended to the toe of the Japan Trench. The deformation and frictional properties beneath the forearc are keys that can help to elucidate ...
