Co-seismic horizontal displacements, which have been obtained from recently released GPS observations on the Akashi Kaikyo Bridge, are examined for their consistency with displacements observed in the vicinity of the bridge. An E18.7°S displacement of 25.0 cm should be removed from them. The adjusted data indicate an additional fault segment beneath Akashi Strait. We construct a new fault model by adding this segment to a model assumed previously. We then recover the slip distribution over the… 
Inversion for the physical parameters that control the source dynamics of the 2004 Parkfield earthquake
A fully dynamic inversion for the earthquake source process, in which the geometry of the rupture area, the stress conditions, and frictional properties on the fault are obtained, is carried out by
Rupture Process of the Chi-Chi (Taiwan) Earthquake in 1999
The rupture process of the 1999 Chi-Chi, Taiwan earthquake is investigated by using co-seismic surface displacement GPS observations and far field P-wave records. In according to the tectonic
Tomography of the 1995 Kobe earthquake area: comparison of finite‐frequency and ray approaches
SUMMARY We determined a detailed 3-D crustal model in the 1995 Kobe earthquake (M 7.2) area in southwest Japan using both finite-frequency and ray tomography methods. Our finite-frequency tomography
Numerical Simulation of Sliding of an Earth Dam During the 1995 Kobe Earthquake
The Kobe Earthquake in Japan caused shallow sliding on the upstream slope below the water level of the Kitayama Dam. This paper briefly stated the results of post-earthquake surveys and tests of this
Spatial Variability of the Directivity Pulse Periods Observed during an Earthquake
The ground velocity pulses generated by rupture directivity effects in the near‐fault region can cause a large amount of damage to structures. Proper estimation of the period of such velocity pulses

We derive scaling relations of outer fault parameters of crustal earthquakes with magnitude Mw of 6.5 to 7.9 using heterogeneous slip models in the world considering fault types. The fault area,


Simultaneous inversion of waveform and geodetic data for the rupture process of the 1984 Naganoken–Seibu, Japan, earthquake
SUMMARY A simultaneous inversion method of strong motion seismograms and geodetic data for inferring earthquake rupture process was developed. We assumed a source model composed of many point-sources
Joint Inversion of Near- and Far-field Waveforms and Geodetic Data for the Rupture Process of the 1995 Kobe Earthquake
The geodetic data, strong-motion waveforms, and far-field waveforms from the 1995 Kobe earthquake (MJMA 7.2) were inverted to determine the rupture process. The geodetic data, including the
Co-seismic Displacements of the 1995 Hyogo-ken Nanbu Earthquake
We present co-seismic displacements of the Hyogo-ken Nanbu earthquake of January 17, 1995, detected by continuous GPS (Global Positioning System) observation, campaign type GPS survey and leveling.
Simultaneous inversion of geodetic and strong-motion data for the source process of the Hyogo-ken Nanbu, Japan, earthquake
We analyze strong ground motions and geodetic data simultaneously with the multiple time-window method in order to infer the source process and the fault geometry of the Hyogo-ken Nanbu earthquake .
Slip History of the 1995 Kobe, Japan, Earthquake Determined from Strong Motion, Teleseismic, and Geodetic Data
Near-source ground motions, teleseismic body waveforms, and geodetic displacements produced by the 1995 Kobe, Japan, earthquake have been used to determine the spatial and temporal dislocation
Minute Locating of Faulting beneath Kobe and the Waveform Inversion of the Source Process during the 1995 Hyogo-ken Nanbu, Japan, Earthquake Using Strong Ground Motion Records
We estimated the source process of the 1995 Hyogo-ken Nanbu (Kobe), Japan, earthquake based on: 1) locating buried fault planes in the Kobe area by examining particle motion at observation stations
Source process of the 1995 Kobe earthquake: Determination of spatio-temporal slip distribution by Bayesian modeling
The Kobe (Hyogo-ken Nanbu) earthquake ( MS 6.8) occurred on 16 January 1995, in western Japan, bringing about a tremendous disaster. We constructed its source model by determining a spatio-temporal
Rupture Process of the Kobe, Japan, Earthquake of Jan. 17, 1995, Determined from Teleseismic Body Waves.
The source process of the 1995 Kobe earthquake is determined using teleseismic body waves. The source parameters obtained for the total source are: focal mechanism [strike, dip, rake] equal to [233°,
Detailed Mapping of Focal Mechanisms in/around the 1995 Hyogo-ken Nanbu Earthquake Rupture Zone
Earthquake focal mechanisms before and after the 1995 Hyogo-ken Nanbu earthquake have been investigated using seismic records from regional seismic networks. Before the mainshock, seismicity was very
The epicenter of the main shock of the 1995 Hyogoken-Nambu earthquake was very close to the construction site of the Akashi Kaikyo Bridge, which will be a three-span, two-hinge stiffening truss
