| Abstract: | The parameters of two M L4.0 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. |
| Keywords: | characteristics of anomaly electromagnetic wave groundwater level escaped helium gas |
