| 摘 要： | 1998年5月～7月中国地震局物探中心在伽师震区布置了一个40×50km2的三维地震观测台网,布置了19台轻便地震仪,在二个月的时间里接收到近700个地震事件,并接收了十一个炮点的人工地震资料.对天然地震资料进行了精确定位,震级大于26的地震计算了震源机制解,并进行了讨论.最后对伽师10次6级以上地震的震中位置及能量的释放过程以及与坷坪断裂的关系进行了初步探讨

| Abstract: | We deployed a 50km by 40km seismic network in JiaShi strong earthquake area. Nineteen Portable seismographs were deployed in the network. During two months,about seven hundred earthquakes were recorded simultaneously by three or more stations. We also recorded artificial seismic signals of eleven shot points. We first located the earthquake epicenter and estimated the source mechanism using P wave first motion. And then analyses the character of strong earthquake epicenter distribution and migrating with time. At last we discussed relation between JiaShi strong earthquakes and KoPin fault. |
