| 摘 要： | 高精度ＧＰＳ测网监测资料表明，川滇菱形断块近期已趋活跃，块体向东南到南方向运动，且应变速率大，形成四个应力聚积区．龙门山地区地壳活动相对平稳。继丽江地震之后，西昌、详云—楚雄地区可能孕育地震，应特别关注。

| Abstract: | The data obtained from a high-preciSion GPS net measurement indicate that the ChuanDian rhombus block is active recently, moving south-southeas t wards wit h a re fatively largestrain rate. As a result, four areas of stress-concentration are formed. The crust along Longmengshan appears relatively stable. Following the recent Lijiang earthquake, both Xichang and Xiangyun--Cuxiong regions are probably pregnancy of next earthquakes,and hence need to be specially monitored. |
