Journal ArticleDOI
Episodic slow slip events in the Japan subduction zone before the 2011 Tohoku-Oki earthquake
Yoshihiro Ito,Ryota Hino,Motoyuki Kido,Hiromi Fujimoto,Yukihito Osada,Daisuke Inazu,Yusaku Ohta,Takeshi Iinuma,Mako Ohzono,Satoshi Miura,Masaaki Mishina,Kensuke Suzuki,Takeshi Tsuji,Juichiro Ashi +13 more
TL;DR: In this paper, the authors describe two transient slow slip events that occurred before the 2011 Tohoku-Oki earthquake, which induced increases in shear stress, which in turn triggered the interplate earthquakes.
Journal ArticleDOI
Frontal wedge deformation near the source region of the 2011 Tohoku-Oki earthquake
Yoshihiro Ito,Takeshi Tsuji,Yukihito Osada,Motoyuki Kido,Daisuke Inazu,Yutaka Hayashi,Hiroaki Tsushima,Ryota Hino,Hiromi Fujimoto +8 more
TL;DR: In this paper, an ocean-bottom pressure gauge was installed before the 2011 Tohoku-Oki earthquake on a frontal wedge, which formed an uplift system near the Japan Trench.
Journal ArticleDOI
Coseismic slip distribution of the 2011 off the Pacific Coast of Tohoku Earthquake (M9.0) refined by means of seafloor geodetic data
Takeshi Iinuma,Ryota Hino,Motoyuki Kido,Daisuke Inazu,Yukihito Osada,Yoshihiro Ito,Mako Ohzono,Hiroaki Tsushima,Syuichi Suzuki,Hiromi Fujimoto,Satoshi Miura +10 more
TL;DR: In this paper, the authors estimate the coseismic slip distribution based on terrestrial GPS observations and all available seafloor geodetic data that significantly improves the spatial resolution at the shallow portion of the plate interface, revealing that an extremely large (greater than 50 m) slip occurred in a small (about 40 km in width and 120 km in length) area near the Japan Trench and generated the huge tsunami.
Journal ArticleDOI
Prevalence of viscoelastic relaxation after the 2011 Tohoku-oki earthquake
Tianhaozhe Sun,Kelin Wang,Takeshi Iinuma,Ryota Hino,Jiangheng He,Hiromi Fujimoto,Motoyuki Kido,Yukihito Osada,Satoshi Miura,Yusaku Ohta,Yan Hu +10 more
TL;DR: This work shows that new seafloor GPS observations immediately after the great Tohoku-oki earthquake provide unambiguous evidence for the dominant role of viscoelastic relaxation in short-term postseismic deformation, and demonstrates that the landward motion is a consequence of relaxation of stresses induced by the asymmetric rupture of the thrust earthquake.
Journal ArticleDOI
Quasi real‐time fault model estimation for near‐field tsunami forecasting based on RTK‐GPS analysis: Application to the 2011 Tohoku‐Oki earthquake (Mw 9.0)
Yusaku Ohta,Tatsuya Kobayashi,Hiroaki Tsushima,Satoshi Miura,Ryota Hino,Tomoji Takasu,Hiromi Fujimoto,Takeshi Iinuma,Kenji Tachibana,Tomotsugu Demachi,Toshiya Sato,Mako Ohzono,Norihito Umino +12 more
TL;DR: In this article, an algorithm to detect/estimate static ground displacements due to earthquake faulting from real-time kinematic GPS (RTK-GPS) time series was developed.
