AN ANALYSIS OF HYDROCHEMISTRY ANOMALY PRIOR TO MODERATE AND SMALL EARTHQUAKES

In the paper,the characters of hydrochemieal anomalous variations prior to some moderate and small earthquakes in and around Guangdong province are analysed,and the difference of these characters from those before major earthquakes of other regions of China and the cause of these differences are discussed,too,and then,it has been indicated to exist hydrochemical sensitive components in groundwater as premonitory symptoms.
