九江-瑞昌5.7级地震地质灾害特征及发震构造

Seismogenic Structure and Geological Disaster Characteristics of Jiujiang-ruichang 5.7 Earthquake

  • 摘要: 以九江-瑞昌5.7级地震的大量现场第一手资料为基础,从烈度等震线、发震构造调查与分析和地震地质灾害特征等多方面、多角度地调查,分析和研究该地震的发震构造。先通过断层活动性、地震震级与发震构造长度关系等地质分析得出可能的发震构造;再通过对烈度等震线、各种地震地质灾害分布特征的分析研究,根据极震区长轴和地震地质灾害优势分布走向得到可能的发震构造;最后综合分析地质和地震地质灾害研究结果。结果的一致性表明瑞昌-武宁断裂为九江-瑞昌5.7级地震的发震构造。

     

    Abstract: Based on a large number of on-site first-hand data of Jiujiang-ruichang magnitude 5.7 earthquake, investigation, analysis and research work are carried out in many aspects, such as earthquake line of intensity, seismic structure investigation and analysis, seismic geological disaster characteristics and so on. Firstly, a possible seismogenic structure is obtained through geological analysis, such as fault activity and the relationship between earthquake magnitude and seismic structure length, and then another seismogenic structure is determined through the analysis of the distribution characteristics of seismic lines and various seismic geological disasters according to the dominant distribution of long axis and seismic geological hazards in meizoseismal area, finally the two possible seismogenic structures are comprehensive analyzed. The high consistency of the two results indicated that the Ruichang-wuning fault may be the seismogenic structure of Jiujiang-ruichang 5.7 earthquake.
