3-D Modelling of Plate Interfaces and Numerical Simulation of Long-term Crustal Deformation in and around Japan     

Chihiro Hashimoto  Kenji Fukui  Mitsuhiro Matsu’ura 《Pure and Applied Geophysics》2004,161(9-10):2053-2068

— We developed a 3-D simulation model for long-term crustal deformation due to steady plate subduction in and around Japan by incorporating viscoelastic slip-response functions into a realistic 3-D plate interface model, constructed on the basis of the topography of ocean floors and hypocenter distributions of earthquakes. The lithosphere-asthenosphere system is modelled by an elastic surface layer overlying a Maxwellian viscoelastic half-space. Kinematic interaction at plate interfaces is rationally represented by the increase of tangential displacement discontinuity (fault slip) across the interfaces. With this model, giving the steady slip rates at plate interfaces calculated from NUVEL-1A, we simulated long-term crustal deformation due to steady plate subduction in and around Japan. The simulated crustal deformation pattern is characterized by steep uplift at island arcs, sharp subsidence at ocean trenches and gentle uplift at outer rises. The numerical results show the strong dependence of the deformation pattern on the 3-D geometry of plate interfaces.  相似文献

Damage to Residential Fills in the 1995 Hanshin-Awaji Earthquake     

Nobuyuki Yoshida  Masaru Nishi  Mitsuhiro Nanbu 《Natural Hazards》2001,23(1):87-97

This paper summarizes the features of ground damage toresidential fills due to the 1995 Hyogo-ken NanbuEarthquake in Japan. Many residential lands sufferedground damage to various extents in the earthquakeevent. Permanent deformation took place ingently-sloping residential fills. Some slopes asgentle as four degrees exhibited landslide-likedownward movements from dozens to hundreds ofcentimeters, so on. It is suggested that liquefactionmight be a dominant factor for displacements ingently-inclined residential fills.  相似文献   

Seasonal variation of atmospheric 210Pb and Al in the western North Pacific region     

Shizuo Tsunogai  Takayoshi Kurata  Toshitaka Suzuki  Khchiro Yokota 《Journal of Atmospheric Chemistry》1988,7(4):389-407

The atmospheric concentration of ²¹⁰Pb was determined for two years at six stations in the western North Pacific region. The following results were obtained and discussed by comparing them with those of Al. The atmospheric concentration of ²¹⁰Pb varied widely from week to week, but the degree of variation was about a half that of Al. Contrary to Al, the year-to-year variation of ²¹⁰Pb was not pronounced and its seasonal variation was well expressed by a sine curve. The ²¹⁰Pb concentration did not show a marked latitudinal variation and its base-line concentration was high in the surface air over the North Pacific. These suggest that atmospheric ²¹⁰Pb has a longer residence time, due to its transportation through higher altitudes and deposits much more evenly onto the Earth's surface and the ocean, as compared with Al in mineral dust which is larger in size in the source region.  相似文献

Construction of surface wind stress fields with high temporal resolution using ERS-1 scatterometer data     

Masahisa Kubota  Hidekazu Yokota 《Journal of Oceanography》1998,54(3):247-256

Wind stress fields with high temporal resolution over the North Pacific have been constructured by using ERS-1 scatterometer data. A simple objective analysis, a successive correction method, was used to construct the fields. Several necessary parameters used in the method are examined by a simulation based on the climatological data. The meridional decorrelation scale of the wind stress depends strongly on the season, while the zonal decorrelation scale is highly stable. We determined the decorrelation scale depending on the location and the time and applied to the successive correction method. The monthly mean field constructed by averaging the daily mean data is free from an aliasing error, which is a serious problem if a simple monthly averaging is applied. The daily wind stress data obtained in the present study represent small time- and spatial-scale variation and large amplitudes compared with data interpolated from simple monthly mean data. The satellite-derived data are also compared with in situ data obtained by meteorological buoys. The satellite wind speeds are lower than in situ wind speeds for every buoy. This underestimation is not due to the present objective analysis, but due to the original data, the ERS-1 Scatterometer Value-Added Product.  相似文献
