The Application of Seismogenic Fault Method in Active Fault Detection
摘要
Abstract
The precisely relocated hypocenter of small earthquakes shows linear or zonal distribution,which can be used to determine the quantitative geometries of seismogenic fault by fitting a spatial plane through mathematical method and then to reveal the relationship between the earthquake spatial distribution and active tectonics.Using the seismicgenic fault fitting method,the geometries structure and motion mode of the seismogennic fault of the 1976 Tangshan M7.8 earthquake,the 1668 Tancheng M8 1/2 earthquake and the 2013 Lushan M7.0 blind earthquake is determined,the parameters is relatively consist with researches of deep structure detections which shows that the seismicgenic fault fitting method has important significance to active fault detection.关键词
