摘要
吸取唐山大地震的教训首先要加强抗震工作。1976年唐山地震是当时河北凹陷地震带处在活动期的加速释放阶段产物。近期印尼弧形地震带的强震频繁,地震资料表明,该带的浅源地震也正处在活动期的应变能加速释放阶段。根据前震活动对强震作短临预测既已获得突破,有待在世界范围内再见成功震例。地震前兆研究需在争辩中深入。
To draw a lesson from the great Tangshan earthquake we should further strengthen the work on earthquake engineering. The 1976 Tangshan earthquake was a manifestation that the Hebei depression seismic zone was in the stage of accelerated strain energy releasing at that time. Recently there have occurred several strong earthquakes in the Indonesia arc seismic zone. An examination of M≥7 shallow earthquakes in this seismic zone after 1900 reveals that now it is also in a stage of accelerated energy releasing. We are expecting the appearance in the world of the second example of the successful impending prediction of a strong earthquake based on sequential foreshock activity. The seismic precursory study should be promoted in a process of arguing and debating.
