华北地区地震烈度衰减模型的建立

MODEL OF THE SEISMIC INTENSITY ATTENUATION FOR NORTH CHINA

    摘要
  • 摘要: 利用20世纪华北地区37次中强地震事件的89条等震线数据,拟合了该地区地震烈度衰减关系。主要选取了M≥5.0的地震事件。与以往的地震烈度衰减关系相比,在计算中强地震烈度时,精度上得到了相应地提高。充分反映了华北地区地震烈度衰减较慢的特点。

     

    Abstract: Seismic intensity attenuation for north china is fitted by using 89 isoseismal lines from 37 earthquakes in this region.The earthquakes are mainly selected by M(M≥5.0).Compared with the past model, the accuracy is improved by using the data of moderately strong earthquakes.The model shows that north china has a low seismic intensity attenuation.
