【摘要】：基于孕震断层多锁固段脆性破裂理论,以板块边界和区域性大断裂作为主控条件,修订了1.0版环太平洋、大洋海岭与大陆裂谷地震带地震区划分图.从孕育周期界定与主震事件判识角度,采用新发展的最小有效性震级确定方法和地震事件量级匹配原则,先修订不合理的地震震级参数,而后界定地震区孕育周期、判识其主震事件并分析其未来震情,得到比之前分析更好的结果.本文所得结论可供有关国家相关部门参考,以采取有效防震减灾措施.
[Abstract]:Based on the brittle fracture theory of multi-locking segment of seismogenic fault and taking the plate boundary and regional large fault as the main control condition, the 1.0 edition is revised around the Pacific Ocean. From the point of view of defining the gestation period and distinguishing the main shock events, the newly developed minimum effective magnitude determination method and the order of magnitude matching principle of earthquake events are adopted. The unreasonable earthquake magnitude parameters are revised first, then the preparation period of the earthquake region is defined, the main shock events are identified and the future earthquake situation is analyzed. The results obtained in this paper are better than those before. The conclusions obtained in this paper can be used as reference for the relevant departments of the countries concerned in order to take effective earthquake prevention and mitigation measures.
