- Abstract:
- We synthetically analyzed the anomalies before the 38 groups of earthquakes(M≥5)since 1970 in the Yunnan region,and obtained the common characteristics of the anomalies.The frequency of small earthquakes usually increases before the earthquakes(M≥5); the durations of anomalies of M≥6 earthquakes are longer than those of M5-6 earthquakes; the wider the anomalies distribute,the bigger the magnitude of the earthquake(M≥5); the ending of some tendentious precursory anomalies and the increasing of new abrupt anomalies can be considered as the sign of the earthquake preparation going into short-term and impending-earthquake period.
