2023/02/06 土耳其M7.6地震破裂模型
Rupture models of the 6th Feb. 2023 Türkiye Mw7.6 earthquake
概述
本次地震发生于2023年2月6日10:24(UTC)，矩震级Mw=7.6，破裂持续时间约为25秒.
远震反演所需数据来自于IRIS，采用Ruptel 3.0软件进行反演(Zhang et al., 2012)，格林函数采用QSSP程序(Wang et al., 2017)计算，所用一维速度结构为AK135模型(Kennett et al., 1995).
强震反演所需数据来自于AFAD,破裂模型的反演基于迭代反褶积叠加(IDS)方法(Zhang et al., 2014; Zheng et al., 2020)，格林函数采用QSSP程序(Wang et al., 2017)计算，所用一维速度结构提取自CRUST1.0模型(Laske et al., 2012).
