1998—2004年滇西地区重力场演化与Ms≥6.0地震
RELATIONS BETWEEN CHANGES OF GRAVITY FIELD AND Ms≥6.0 EARTHQUAKES IN WESTERN YUNNAN DURING 1998—2004
【摘要】 对滇西地震实验场1998—2004年的重力时空动态演化特征的研究表明:重力场变化与该区断裂活动密切相关;相邻两期动态变化对测区内发生的2001年10月永胜6.0、2001年1月姚安6.5、2003年7月大姚6.2和2003年10月大姚6.1级地震均有较好的反映。
【Abstract】 On the basis of the mobile gravity data in western area of Yunnan province during 1998—2004,the dynamically evolutional characteristics of gravity field in time and space are researched.The results show that 1)the changes of gravity field are closely relative to fault activity;2)the Yongshen %M %s6.0,Yaoan %M %s6.5 and Dayao %M %s6.2,%M %s6.1 earthquakes occured in the area were reflected in the sequential phase dynamic change of gravity field.
