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.
