摘要
研究了历史地震对鄂尔多斯地块内部县(市)的影响烈度,发现鄂尔多斯地块周缘发生的强震对其内部县(市)的影响十分显著。自1484年以来,鄂尔多斯地块内部93.7%的县(市)遭受过Ⅵ度的破坏,55.7%的县(市)遭受过Ⅶ度破坏,5.1%的县(市)遭受过Ⅷ度破坏。新一代区划图中应考虑历史地震的影响,提高该区的地震危险性。
This paper examines the seismic affected intensities of counties and cities in the Erdos area,and shows historical strong earthquakes around Erdos affected these counties and cities greatly.Since 1484,93.7% of the counties and cities in the Erdos area suffered Ⅵ affected intensity,55.7% of them Ⅶ,and 5.1% Ⅷ.So the influence of historical earthquakes should be considered and its seismic risk criterion should be raised in next generation seismic zoning map.
