摘要
用双差定位方法对1668年郯城8(1/2)级地震震中附近1974年以来400余个中、小地震重新进行定位。结果显示现代中、小地震震中分布仍集中于地震破裂带上,带状集中区与地质考察推测得到的发震断层安丘-莒县断裂的走向吻合。
Using the double difference earthquake location algorithm,we relocate more than 400 moderate and small earthquakes near the epicenter of 1668 Tancheng 8(1/2) earthquake since 1974.The relocated result shows that the modern moderate and small earthquakes were still concentrated in the Tancheng earthquake rupture zone.The strike of the bandy concentrated zone accords with that of the generating Anqiu-Juxian fault speculated by geological surveying.
