Source rupture process of the 2011 Tohoku - Oki earthquake derived from the strong - motion records
We reveal the source rupture process using the strong-motion data by the inversion analysis. The derived slip distribution shows one prominently large slip area extending from the hypocentre area to the shallow part of the fault along the trench axis, which is located far off the coastal region extensively damaged by the tsunamis. The shallow main rupture started 60 seconds after the initial br...
متن کاملVariations of Strong Earthquake Ground Motion In
Accelerograms recorded at six stations in the metropolitan Los Angeles area during the Borrego Mountain, 1968, the Lytle Creek, 1970, and the San Fernando, 1971, earthquakes in southern California have been studied. In comparing the ground motions recorded during different earthquakes at each of the six stations and in correlations of these motions recorded at different stations during the same...
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 کاملGround uplift related to permeability enhancement following the 2011 Tohoku earthquake in the Kanto Plain, Japan
We investigated the post-seismic surface displacement of the 2011 Tohoku earthquake around the Kanto Plain (including the capital area of Japan), which is located approximately 400 km from the epicenter, using a global positioning system network during 2005–2015 and persistent scatterer interferometry of TerraSAR-X data from March 2011 to November 2012. Uniform uplift owing to viscoelastic rela...
متن کاملRapid Estimation of Earthquake Source and Ground-Motion Parameters for Earthquake Early Warning Using Data from a Single Three- Component Broadband or Strong-Motion Sensor
We propose a new algorithm to rapidly determine earthquake source and ground-motion parameters for earthquake early warning (EEW). This algorithm uses the acceleration, velocity, and displacement waveforms of a single three-component broadband (BB) or strong-motion (SM) sensor to perform real-time earthquake/noise discrimination and near/far source classification. When an earthquake is detected...
