郯庐断裂带南段及邻区中小地震地震波衰减特征研究
Study on Attenuation Characteristics of Seismic Wave of Mid-small Earthquakes in the Southern Segment of Tanlu Fault Zone and Its Adjacent Areas
摘要
Abstract
Based on earthquake data recorded in Anhi seismic network, the K-value of amplitude attenuation coefficient and the a-value of predominant frequency of seismic wave of mid-small earthquakes in southern segment of Tanlu fault zone and its adjacent areas were calculated with the use of single earthquake multiple fitting calculating method. In addition, the space-time variety characteristics of K -value and a -value was researched, and the relationship with moderate earthquakes in East China and the value of Qc were discussed. The findings of this paper may have a practical significant on the medium and long term earthquake prediction and post-earthquake trend judgment.关键词
