    黄土高原及邻区的地震滑坡

    EARTHQUAKE-TRIGGERED LANDSLIDES IN THE LOESS PLATEAU AND ITS ADJACENT AREAS

    • 摘要: 我国黄土高原地区覆盖62.46104km2,构造活动活跃,是滑坡与泥石流等地质灾害的多发区与易发区,有丰富的历史地震与其触发滑坡记录。本文对黄土高原及邻区(100 km缓冲区)的地震与其触发滑坡进行总结与归纳。结果表明黄土高原及邻区有395次震级M 5的地震记录。其中M 8级地震6次,7 M 8级地震20次,6 M 7级地震74次,5 M 6级地震295次。这395次地震中有98次地震有同震滑坡记录或详细信息,对这些地震滑坡的信息进行了简要介绍。简要介绍了2013年6.7级岷县、1920年8.5级海原、1927年8.0级古浪、1995年甘肃永登5.8级等4次地震触发滑坡的情况。最后对黄土高原及邻区的地震滑坡研究方向进行了展望。本研究可为黄土高原及邻近地区的地震与滑坡的科学研究与防灾减灾提供重要基础资料。

       

      Abstract: The Loess Plateau area of China, with an area 62.46104km2 and characterized by high tectonic activities, is an area with a large number of and prone of landslides and debris flows. It has a rich historical earthquakes and triggered landslides in the area. This study summarizes the earthquakes and triggered landslides in Loess Plateau and its adjacent areas(100-km-buffer zone). The results show that there are 395 earthquake records of magnitude M5 in the Loess Plateau and its adjacent areas. Among them, there were 6 earthquakes of magnitude M8 or larger, 20 earthquakes between M7 and M8, 74 of 6 M 7, and 295 events of 5 M 6. Among the 395 earthquakes, there are 98 earthquakes have coseismic landslide records or detailed information. The information of landslides triggered by these earthquake is briefly introduced. This study also briefly introduces the landslides triggered by four earthquakes, such as the 2013 Minxian M6.7, 1920 Haiyuan M8.5, 1927 Gulang M8, and 1995 Yongdeng M5.8 events. Finally, the research prospects of earthquake-triggered landslide in Loess Plateau and its adjacent areas is proposed. This study can provide important basic information for scientific research and prevention and reduction of earthquakes and associated landslides in the Loess Plateau and adjacent areas.
