根据川滇地区7级地震活动特征、四川7.0级地震与云南地震活动状态的统计规律、川滇MS≥6.7强震幕式活动特征、云南5级地震活动特征以及汶川地震后川滇3级地震活动特征等,分析了汶川地震后云南的地震趋势,初步认为:云南地区1~2年内进入新一轮强震活跃期的可能性小; 川滇地区下一强震活动区应该以四川为主,而云南MS≥6.7地震的活动强度要比四川低,最大地震可能为7.0级左右,川滇菱形块体为短期内最可能发生MS≥5地震的区域。

We introduce the characteristics of MS≥7.0 earthquake activities in the Sichuan-Yunnan region,the relationship between MS≥7.0 earthquakes in Sichuan and the active/quiet period of MS≥6.7 earthquakes in Yunnan,the characteristic of MS≥6.7 earthquake episodes in the Sichuan-Yunnan region,the characteristics of MS≥5.0 earthquake activities in the Yunnan region,the distribution of MS≥3.0 earthquakes in the Sichuan-Yunnan region after the Wenchuan MS8.0 earthquake,and analyzed the earthquake tendency in Yunnan after the Wenchuan earthquake.It is not too possible for the Yunnan region to enter a new round of active period in the coming 1-2 years.The Sichuan region will be the major seismicity zone of next active period in the Sichuan-Yunnan region,and the seismicity in Yunnan is lower than that in Sichuan,possible maximum magnitude about 7.0.The Sichuan-Yunnan rhombic block is the most possible place where MS≥5 earthquake occurs.
