Macroscopic anomalies from“Earthquake Cases in China”are statistically analyzed in the article． The conclusion is as follows: The probability of macroscopic anomalies arises before earthquake increases with magnitude． The larger the earthquake magnitude is，the more the macroscopic anomalies arise． Arise time law of macroscopic anomalies as follows: There are few macroscopic anomalies at the beginning． With time advances the number of macroscopic anomalies increases． Increase of macroscopic anomaly quantity accelerates impending earthquake and reaches climax when earthquake breaks out． The distribution rule of macroscopic anomalies is as follows: macroscopic anomalies arise at epicenter at the beginning and spreads out． Finally macroscopic anomalies explosively arise at the epicenter area．
