| 摘 要： | １９９４年第二季度，全球地震活动仍维持中等水平。爪哇岛以南爪哇海沟内发生以７．２级地震为主的强震序列。南美洲接连发生深震，６月９日玻利维亚北部发生大深震，有感范围极大。大洋岛弧带地震频数占全球半数以上，本季度最大地震也发生在此。亚欧带继续维持中等水平的活动，亚欧带西段地震活动的发展需要继续监视和跟踪。

| Abstract: | The global seismicity still remained at medium level during the second quarter of the year 1994.There was a strong earthquake sequence with a mainshock of Ms 7.2 occurring in the Java Trenchsouth of the Java Island.There were a series of deep earthquakes occurring consecutively in SouthAmerica. A large deep earthquake took place on June 9 in northern Bolivia,with wide-spread feltrange. The earthquakes occurring alung the oceanic island-arc belt made up more than half of theglobal total,with the largest one occurring there during this quarter.The seismic activity also re-mained at medium level in the Eurasian seismic belt, but the seismicity along the west segment of theEurasian belt deserves close monitoring and tracking. |
