摘要
分析了2002年6月17日海城4 0级地震前后海城一带重力场时空变化情况,重力点值和段差值变化在时间和幅度上具有明显的同步性,分析认为此次地震的发生与重力场变化有着密切关系。
Befor and after Haicheng earthquake of ML40 on June 17,2002,the timespace varing of gravity field in Haicheng area is very obvious.The gravity station value and the secteor difference have synchronism on time and range.It is consided that there is close relation between this event and gravity field change.
