The 2011 Tohoku-Oki Earthquake: Displacement Reaching the Trench Axis
TL;DR: The difference between bathymetric data acquired before and after the earthquake revealed that the displacement extended out to the axis of the Japan Trench, suggesting that the fault rupture reached the trench axis.
Journal ArticleDOI
Coseismic fault rupture at the trench axis during the 2011 Tohoku-oki earthquake

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
Large fault slip peaking at trench in the 2011 Tohoku-oki earthquake.
TL;DR: This slip distribution indicates that dramatic net weakening or strengthening of the shallow fault did not occur during the Tohoku-oki earthquake, and high-resolution bathymetry differences before and after the earthquake across the trench axis are modeled.
Journal ArticleDOI
Learning from crustal deformation associated with the M9 2011 Tohoku-oki earthquake
Kelin Wang,Kelin Wang,Tianhaozhe Sun,Lonn Brown,Ryota Hino,Fumiaki Tomita,Motoyuki Kido,Takeshi Iinuma,Shuichi Kodaira,Toshiya Fujiwara +9 more
TL;DR: Numerous observations pertaining to the magnitude 9.1 earthquake were reported in the last few days as discussed by the authors. But none of these observations were considered reliable data sets, and none were reliable observations were available.
Journal ArticleDOI
Seamounts, knolls and petit-spot monogenetic volcanoes on the subducting Pacific Plate
TL;DR: In this article, the authors presented the results of an exploratory search for these new kind of petit-spot volcanoes along the trenches in the Pacific Ocean, with an emphasis on the Japan and Tonga trenches.
