摘要
应用GPS、水准、重力和跨断层形变观测资料,在以往研究成果的基础上,分析中国大陆现今地壳形变场、重力场变化形态,分析主要活动断裂带应变积累状态,识别强闭锁、高应变积累段,结合大震对区域应变积累的影响,估计未来10年尺度中国大陆地区可能发生大地震的危险区域.
Abstract
Based on previous research results,the present-day crustal deformation and gravity field in mainland China are analyzed using the data of GPS,leveling,gravity and cross-fault deformation.We analyzed strain accumulation on the major faults,and identifed locked or high strain accumulation segments.Combining the effects of large earthquakes on the study area,the long-term (10 years) probability of large earthquakes in mainland China are estimated.
