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 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 کاملMouse circadian rhythm before the Kobe earthquake in 1995.
Mouse circadian diagrams recorded at Osaka University showed unusual mouse behavior before the Kobe earthquake on January 17th, 1995. The locomotive activities on January 16th showed drastic increases, several times above the standard deviation, during both sleep and active periods, indicating that mice perceived of some preseismic signals.
