Abstract

Abstract: Zhangbei Ms6.2 earthquake(41.1°N,114.3°E)on January 10,1998 was an-Other eminent event after Datong Ms6.1 shoek in 1989 in North China.The spatial andTemporal eharaeteristics of anomalies near by epieenter(△≤200km)show that anomalies oeeurred in groups and by stages,reflecting the strengthening process of field stress. Pri-mary diseussion on anomaly mechanism is also given in the paper.

Key words: Area nearby epieenter, Anomaly eharaeteristies, Spatial and temporalevolution, Anomaly meehanism.
