分析了鲁东-黄海活动地块构造背景和历史地震活动特征,探讨了该地块强震前中期阶段地震活动的演化图像,得到该区域强震前中[等]地震密度增长率能够较好反映强震前中期阶段的异常特征。
This paper uses moderate earthquake growth rate to depict the acceleration growth of moderate earthquake activity in the.
文中用中[等]地震增长率来刻划强震孕育过程中中[等]地震活动的加速增长,结果表明:中[等]地震聚集活动密度的增长率能够较好地反映强震前中期异常变化特征,对各活动地块的分析表明华北地块中[等]地震增长率达到180%以上时,未来1～3a中[等]地震异常聚集区及其附近会发生强震;而西域、青藏和滇缅地块中[等]地震增长率达到250%以上时,应注意中[等]地震异常聚集区及其附近强震的发生。
