STUDY ON THE PRECURSORY ANOMALY BEFORE TWO ML 4.0 EARTHQUAKES OCCURRED IN PUYANG
The parameters of two ML4.0 earthquakes occurred in Puyan are introduced. Some anomalies of electromagnetic wave, groundwater level and helium gas had appeared before the two events. The characteristic of these anomalies is analyzed. As the beginning time, duration and magnitude of the anomalies are different in stations, it shows the complicated feature of the anomalies.
