基于ArcGIS的湖北地震监测台站空间分布特征研究

Study on spatial distribution characteristics of Hubei seismic monitoring stations based on ArcGIS

基于ArcGIS平台,通过湖北地震监测台站分布与行政区划、活动断裂带、地震动峰值加速度区划之间的空间关系,定量研究湖北地震监测台站的空间分布特征。研究表明,在湖北部分地市存在地震监测空白或薄弱区域;超50%的地球物理监测台站和约三分之一的测震台站在距活动断裂10 km的范围内;所有地震台站均位于地震烈度Ⅵ级以上区域。

Based on the ArcGIS platform,this study quantitatively studies the spatial distribution characteristics of seismic monitoring stations in Hubei Province through the spatial relationship between the distribution of seismic monitoring stations in Hubei Province and the administrative division,active fault zone and ground motion peak acceleration zoning.The results show that there are gaps or weak areas in seismic monitoring stations in Hubei Province.More than half of the geophysical monitoring stations and about one-third of the seismic stations in the province are within 10 km of the active fault.Additionally,all seismic stations in the province are situated in areas with seismic intensity above level VI.
