The conclusion is as follows: The probability of occurrence of macroscopic anomalies before earthquakes increases with magnitude. The larger the earthquake magnitude, the more macroscopic anomalies appear. The temporal distribution of macroscopic anomalies is as follows: There are few macroscopic anomalies at beginning; as time goes on,the number of macroscopic anomalies increases; the increase of macroscopic anomaly quantity accelerates with the impending earthquake and reaches a climax when the earthquake breaks out. The spatial distribution pattern of macroscopic anomalies is as follows: macroscopic anomalies appear at the epicenter at the beginning,then spread out,and finally arise explosively at the epicenter area.展开更多

The credible anomalies occurring from February 1 to June 10,2008 were treated as macroscopic anomalies,and their space-time distribution was studied. The research indicates that in time distribution,the number of macroscopic anomalies peaked before the earthquake,and these peak values appeared twice after the earthquake. In space distribution,the distribution of macroscopic anomalies before the earthquake was the same as that after the earthquake. In this paper,the mechanism of occurrence of macroscopic anomalies and the role of macroscopic anomalies in forecasting earthquake were also discussed.展开更多
