摘要
Basing on the prediction opinion and criteria of Yiliang M5. 7、5. 6 earthquakes,we considered that the main earthquake activity characterstic before Yiliang M5.7、5.6 earthquakes was the earthquake quietude time of M≥6. 0 earthquakes approached to or exceeded its utmost time since 20th centry,and there is lack of M≥6. 0 earthquakes in the period of continuous occurrence of moderate strong earthquakes activity in Yunnan province. The main basis of the short-term earthquake risk were the window effect of Ninglang earthquake and the continuous increase of precursor abnormity items. The concentrating activity area of M≥4. 0 earthquakes provided the clue of earthquake occurrence location judgment. Because of the preparation of Yiliang M5. 7、5. 6 and Burma MS 7.0 earthquakes in the same period,which increased the prediction difficulty of Yiliang M5. 7、5. 6 earthquakes,how ever it also enriched our understanding of earthquake gestation.
