摘要
分析了鲁东—南黄海地块区历史与现代地震活动特征,讨论了地震活动在时间、空间以及应变能积累等方面的演变过程。分析认为,鲁东—南黄海地震区自1839年以来,显示3个中强以上地震密集时段———地震“幕”,当前幕可能还会持续10年左右;根据应变能积累释放图像分析,认为今后3年内本区发生5级以上地震的可能性较大;从空间上认为下一次5.5级地震发生在北部的可能性较大。
The characteristics of historical and modem earthquake activities in Ludong - Nanhuanghal block area are studied,and the temporal and spatial evolution and strain energy accumulation are discused. The results show that there are three periods of moderate and strong earthquakes in Ludong- Nanhuanghai block area since 1839, and the current period may be sustaining for 10 years. Aeording to the strain energy releasing diagram, the earthquakes with Ms≥5.0 will be oecurred in the area in three years, and the next Ms5. 5 earthquake will be occurred possibly in the noah of the block area.
