| 摘 要： | 本文利用华北平原重力资料,统计了重力高特征参数与发生在重力高附近的地震之间的关系。统计结果发现:重力高附近如有M_s≥4级地震发生,它应满足一定的特征条件;最大震级和地震总能量与重力高面积和强度的平方根之积有高度相关性;M_s≥5级地震绝大多数发生在较大的重力高形态矢量附近。根据统计结果预测了本区地震危险区,指出了统计结果的应用条件和物理含义

THE STATISTICAL RESULTS ABOUT THE RELATIONSHIP BETWEEN THE GRAVITATIONAL HIGH AND EARTHQUAKES IN THE NORTH CHINA PLAIN |

| Abstract: | In order to determine the earthquake risk region, the relationship between the gravitational high and earthquakes occurring nearby is statistically studied by using the gravity data of the North China Plain area. The statistical results obtained indicate that the gravitational high must satisfy certain conditions in case of occurrence of an earthquake of magnitude Ms≥4 near the anomaly area. It is found that the greatest magnitude and total seismic energy released are highly correlated to the pr |
