基于构造的测震学参数在鲁东－黄海地块的应用

以基于构造的测震学参数分析为思路，利用地震构造分区和地质构造单元的划分结果，检验了基于活动边界带的测震学参数方法的可行性；将活动地块内部（地质构造复杂且地震活动频繁）构造单元与测震学参数相结合，研究中强震前震源区所在的构造单元测震学参数的变化特征，提取具有中期预测意义的震兆标志，为中强震的预测提供理论依据。结果显示：中强地震前，郯庐断裂带（鲁东-黄海地块西边界带）及扬子地块（鲁东－黄海地块内部构造单元）D、C值异常过程明显，且各有特点，证明了基于活动地块内部构造单元的测震学参数方法具有良好的可行性。

Application of seismometry parameters with structure in the East of Shandong Province and Yellow sea tectonic block

Guided by seismometry parameters analysis based on tectonic method, we make use of the results of seismic tectonic division and geotectonic unit classification, and check the feasibility of the seismometry parameters method, which is based on the active boundary zone. Combining complex geologic structure in the inner active block as well as the geotectonic units when the earthquake occurred with seismometry parameters is made analysis. Through studying the characteristics of the focal region of mid strong earthquake seismometry parameters, we pick up middle-term seismic indexes for earthquake to provide theoretical evidence for mid-strong earthquake prediction. The results shows that before the mid-strong earthquake occurrence, data D and C will become unusual changes lying in the Tancheng-Lujiang fault zone （the west boundary zone of the East of Shandong Province and Yellow sea tectonic block） and Yangtze Block （the inner geotectonic unit of the East of Shandong Province and Yellow sea tectonic block）. It firmly proved the feasibility of the seismometry parameters analysis which is on the basis of the inner geotectonic Units.
