Modeling near‐field tsunami observations to improve finite‐fault slip models for the 11 March 2011 Tohoku earthquake
[1] The massive tsunami generated by the 11 March 2011 Tohoku earthquake (Mw 9.0) was widely recorded by GPS buoys, wave gauges, and ocean bottom pressure sensors around the source. Numerous inversions for finite‐fault slip time histories have been performed using seismic and/ or geodetic observations, yielding generally consistent patterns of large co‐seismic slip offshore near the hypocenter ...
متن کاملThe 2011 Tohoku earthquake and devastating tsunami.
At 14:46 on March 11, 2011, the magnitude-9.0 earthquake attacked Sendai and neighboring cities distributed along the northeast coast of Honshu Island, Japan. Its epicenter is located 130 km east of Sendai (Fig. 1). Unfortunate ly, the strong earthquake generated devastating tsunamis that destroyed many towns and villages near the seashore in Iwate, Miyagi, and Fukushima prefectures. The natura...
متن کاملPost-crisis: earthquake, tsunami, radiation leak and rural health crisis in Japan.
There is no doubt that the huge earthquake on 11 March 2011 off the Pacific coast of Tohoku, Japan, and subsequent tsunami is one of the largest natural disasters in modern history. Unexpected radiation leakage from quake-hit and inundated nuclear power reactors has worsened the crisis. Appropriate management of the situation is paramount but the question is, ‘What is to be done and how to do i...
متن کاملIntroduction to the Special Issue on the 2011 Tohoku Earthquake and Tsunami
The 11 March 2011 Tohoku earthquake (05:46:24 UTC) involved a massive rupture of the plate-boundary fault along which the Pacific plate thrusts under northeastern Honshu, Japan. It was the fourth-largest recorded earthquake, with seismic-moment estimates of 3–5 × 10 N·m (Mw 9.0). The event produced widespread strong ground shaking in northern Honshu; in some locations ground accelerations excee...
متن کاملEstimation of Runup Heights of the 2011 off the Pacific Coast of Tohoku Earthquake Tsunami Based on Numerical Simulations
A strong earthquake (M9.0) occurred at 14 h 46 m (JST) on March 11, 2011 in the Pacific Ocean east of the Tohoku district in the northeast part of Honshu Island, Japan. The earthquake was accompanied by a large tsunami. The main goal of this study is to use numerical modelling to reproduce the observed characteristics of the 2011 tsunami. First, the water elevation records of DART buoys, coasta...
