| Abstract: | Since the M 5.9 and M 6.5 earthquakes of Yao＇an,strong earthquakes in Chongxiong region have been frequently,intensely attacking in a wide range.Researches find： medium and strong earthquakes are active in the Chuxiong-Nanhua seismic zone;M6.0 earthquakes in the south and north sections correspond and reinforce each other;in the 20th century,M 7.0 earthquakes in Yunnan share the time,space and strength features with those in Chuxiong region. |
| Keywords: | Chuxiong region strong earthquake increased activity research |
