Simulations of Long-Period Ground Motions during the 1995 Hyogoken-Nanbu (Kobe) Earthquake using 3D Finite Element Method
Long-period strong motions (> 0.9 second) are simulated in the Kobe area for the mainshock (1/17/95) and the aftershock (2/2/95) of the Hyogoken-Nanbu (Kobe) earthquake. In order to model ground motions in the realistic and highly heterogeneous basin structure, an unstructured 3D FEM (Finite Element Method) is used, which runs efficiently on parallel computers. The simulation results show stron...

متن کاملReliability of Envelope Inversion for the High-Frequency Radiation Source Process Using Strong Motion Data: Example of the 1995 Hyogoken Nanbu Earthquake
This article presents an application of a procedure to invert the highfrequency radiation process at the source during the 1995 Hyogo-ken Nanbu earthquake using the envelopes of acceleration waveforms from 16 stations. The inversion uses genetic algorithms that compare observed ground motions with synthetic ones calculated using empirical Green’s functions. Before the inversion, the reliability...
متن کاملThe Kobe ( Hyogo - ken Nanbu ) , Japan , Earthquake of January 16 , 1995
9 Figure 1 The locations of the 1995 Kobe earthquake and the four other large intraplate earthquakes (Nobi, Tango, Tottori, and Fukui) in Japan since 1890. The mechanisms for the Tango, Tottori and Fukui earthquakes are also shown. The base map showing the Quaternary faults in the region is taken from Huzita (1980) and modified. M.T. is the Median Tectonic Line. Daishinsai (A major earthquake d...
متن کاملChanges in permeability of the Nojima fault damage zone inferred from repeated water injection experiments
In 1995, the Hyogoken-Nanbu earthquake (M 7.3) ruptured the Nojima fault, Awaji Island, central Japan. To investigate the recovery process of a fault zone after a large earthquake, repeated water injection experiments have been conducted every few years in an 1800-m-long borehole near the Nojima fault since 1997. In addition, the groundwater discharge rate and pressure have been observed in an ...
