巴塘6.7级地震和雅江6.0级地震前后三叉口地区重力场变化情况
Gravity field changes compared before and after the M6.7 Batang and the M6.0 Yajiang Earthquake around Shimian area
【摘要】 三叉口地区在1989年巴塘6.7级地震和2001年雅江6.0级地震前的重力场变化显示该地区的地应力呈聚集状态,能量的释放较少;在震后重力场变化显示该地区的地应力呈释放状态,有较大的能量释放。
【Abstract】 The gravity field changes before both the M6.7 Batang Earthquake in 1989 and the M6.0 Yajiang Earthquake in 2001 show an accumlated stress status and the stress energy released from seismic events is less during this period.But the energy released from seismic events is big after the M6.7 Batang Earthquake in 1989 and the M6.0 Yajiang Earthquake in 2001.
