| 摘 要： | 山西及其邻近地区地壳垂直形变出现的两升三降的分布格局,反映出现代构造块体活动在不断增强.通过地震活动和区域形变场分析,可以看出山西地区自50年代以来地震释放能量有不断加强趋势,区域形变出现了有规律的四象限分布.预计今后10年内本区若干危险点有可能成为地震能量大释放地区.

| Abstract: | The format of distribution characterized by two rises and three drops of crustal vertical deformation inShanxi province and its vicinity shows increasingly activity of present-day tectonic block. Through an analysis for seismic activity and regional deformation field, it is found that the seismic energy release trend inShanxi has been increasing since 1950', and that the regional deformation characterizes by regular fourquadrantal distributions. The author forecasts that several danger segments might be the most probably candidate for large release of seismic energy in future 10 years. |
