摘要
运用深浅部构造对比研究、构造解析技术,结合历史地震资料、中强震观测资料分析、地震活动性分析结果,探讨中强震过渡区地震构造环境和地震韵律的研究途径,圈定出新沂—泗县地震危险区。对该危险区进行立体综合剖析,推演出未来中强震发生的空间部位,并预测了该区未来可能发生地震的震源深度、震级、地震长轴衰减方向、地震复发间隔等参数。
based on contrast of deep and shallow structure, tectonic resolution, analysis of historic earthquake and seismicity, the seismotectonic environment and seismic rhythm are studied, and the seismic risk region in Xinyi-Sixian area is presented. Through steric analysis to the risk region, the spacial location of the potential earthquake is located, and the parameter of focal depth, magnitude, major axes and attenuation direction, reoccurrence interval are also predicted.
