| 摘 要： | 1990年6月14日苏联斋桑7.3级强震发生在重力异常梯度带的拐弯处;强震前存在明显的M_s≥3.5级地震围成的空区;空区走向为北西西向,与斋桑强震发震构造走向一致,长轴约170km。1990年2月14日4.0级地震可视为信号震。最后初步讨论了阿勒泰活动区的地震趋势。

| Abstract: | In the paper, some seismicity characteristics before Zesang strong earthquake (M = 7. 3)on June 14, 1990 have been analysed, finding out that this shock took place just at the corner of gravity gradient anomaly zone. There existed an obvious gap before the strong earthquake ,this gap is circuled by several small earthquakes with MS@. 5 and its strike is about north-west-west, which consistent with the earthquake-generating structure of Zesang strong earthquake. The long axis is about 170 km, the recent earthquake tendency around Altay seismic activity zone has been discussed. |
