Journal ArticleDOI
Subducted seamount imaged in the rupture zone of the 1946 Nankaido earthquake
TL;DR: This work used densely deployed ocean bottom seismographs to detect a subducted seamount and proposes that this seamount might work as a barrier inhibiting brittle seismogenic rupture.
Journal ArticleDOI
Coseismic fault rupture at the trench axis during the 2011 Tohoku-oki earthquake
Shuichi Kodaira,Tetsuo No,Yasuyuki Nakamura,Toshiya Fujiwara,Yuka Kaiho,Seiichi Miura,Narumi Takahashi,Yoshiyuki Kaneda,Asahiko Taira +8 more
TL;DR: In this paper, images of the subduction trench next to the Tohoku-oki epicentre, captured using seismic reflection data 11 days after the 2011 earthquake, indicate that fault slip did reach the sea floor.
Journal ArticleDOI
Along-arc structural variation of the plate boundary at the Japan Trench margin: Implication of interplate coupling
TL;DR: In this paper, two kinds of interplate sedimentary units, a wedge-shaped unit and a channel-like unit, have been found to have a lower P wave velocity than the basal part of the overriding island arc crust.
Journal ArticleDOI
Structural factors controlling the rupture process of a megathrust earthquake at the Nankai trough seismogenic zone
Shuichi Kodaira,Eiji Kurashimo,Jin-Oh Park,Narumi Takahashi,Ayako Nakanishi,Seiichi Miura,Takaya Iwasaki,Naoshi Hirata,Kosuke Ito,Yoshiyuki Kaneda +9 more
TL;DR: In this paper, a subducting seamount at the centre of the proposed rupture zone with dimensions of 13 km thick by 50 km wide at 10 km depth was found and the seismic velocity image also showed that the seamount is now colliding with the Japanese island arc crust.
Journal ArticleDOI
Crustal structure across the coseismic rupture zone of the 1944 Tonankai earthquake, the central Nankai Trough seismogenic zone
Ayako Nakanishi,Narumi Takahashi,Jin-Oh Park,Seiichi Miura,Shuichi Kodaira,Yoshiyuki Kaneda,Naoshi Hirata,Takaya Iwasaki,Masao Nakamura +8 more
TL;DR: In this article, the authors investigated differences in deep crustal structures of the rupture zones between the 1944 and 1946 Nankaido earthquakes and showed that the coseismic rupture extends to the Neogene-Quaternary accretionary prism.
