STUDY ON THE RELATION BETWEEN NEIMENG M_S 5.9 EATHQUAKE AND THE PRECURSORY ANOMALY CHARACTERISTICS

On the basis of the much precursory information in Liaoning province,the relation between the two times M_S 5.9 earthquakes and the precusory characteristics in Neimeng and Northeast area was researched.The results showed that there are some precursory anomaly characteristics before the events:(1)precursory anomaly stage rising and falling on the time was accompanied by the occurence and termination of M_S5.9 earthquake,and it has the migration characteristics in the space; (2) the drformation anomaly was mainly observed in the mid-short term precursory anomaly stage,and the anomalies of the underground fluid and geomagnetism were observed in the short-imminent stage.
