震级是根据地震仪的记录,测定地震强度大小的一种量度,是地震学研究所要考虑的一个重要参数。在地震预报研究中,如b值、缺震、震群的确定,空区、地震条带的划分等,都要用到震级。这说明震级的正确与否,对地震学的深入研究起着重要的作用。我们对山东台网计算的震级和北京台网计算的震级进行统计,结果表明,山东台网计算的震级比北京台 Magnitude is a measure of the magnitude of an earthquake based on seismograph records and is an important parameter to consider in seismological research. In the study of earthquake prediction, such as b value, lack of earthquake, the determination of swarm, space, the division of seismic stripes, etc., are used to magnitude. This shows that the magnitude of the correct or not, on the seismology in-depth study plays an important role. We calculate the magnitude of Shandong station network and Beijing station network to calculate the magnitude of the statistics, the results show that Shandong station network magnitude than Beijing
