Abstract: 同震滑动的空间分布估计问题是不适定的，其反演结果存在非唯一性。为了获取稳定的同震滑动分布，本文采用了光滑模型约束的正则化反演方法。算法实施过程中，构建了断层面非均匀离散的滑动量分布光滑约束模型，并设计一种快速稳定的正则化因子求取方法；为了获得合理的滑动分布，采用了非负最小二乘求解方法。理论均匀滑动分布模型的反演试算，验证了反演算法的有效性和稳定性，且非负最小二乘方法能规避不合理的滑动分布。利用光滑约束反演方法反演了2005年Nias地震的同震滑动分布，并与前人的研究结果进行了对比分析。2005年Nias地震反演结果显示：断层面最大滑动量为12.8 m，这与Konca等反演得到的结果一致，且滑动分布所释放的地震矩为9.91 × 1012 Nm，其地震震级为Mw = 8.6，与USGS公布的结果一致。通过理论滑动分布模型和实际震例的反演结果表明，光滑约束正则化反演方法是可行的，并能合理地重建断层面的同震滑动分布。 Estimating the spatial distribution of coseismic slip is an ill-posed inverse problem, and the solution is non-unique. In order to obtain stable solution for coseismic slip inversion, regularization… read more here.
