§1.随着地震观测的发展和观测记录的积累，积累了很多关于地球内部构造的知识。通过地震活动、走时波形分析、接收器函数分析等，例如slab1.0 [Hayes et al.(2012)]和Crust 1.0 [Laske et al.(2013)]等全球尺度的海洋板块和地壳构造模型，并在互联网上公开。以日本列岛为例，以高灵敏度地震观测网Hi-net为代表的基础地震观测网[Okada et al. (2004)，Obara et al.(2005)]的观测记录和构造探查。调查研究的结果表明，空间尺度为10km左右的非均质结构(以下称为长波长非均质结构)。例如，Nakajima and Hasegawa (2007)，Hirose et al.(2008)， Matsubara et al. (2005,2008,2017)，Shiomi et al. (2006，2008)，Nishida et al. (2008)，Koketsu et al. (2009, 2012)， Miyoshi et al.(2017)]。东京大学地震研究所(http://wwweic . eri.u-tokyo.ac.jp/ssjapan/)和防灾科学技术研究所(http:/ / www.hinet.bosai.go.jp/topics/moho/?lang=ja)的说明ブサイト上,它们的一部分被公开。以Fig. 1为例，全国一次地下结构模型[Koketsu et al. (2012); http:/ www.jishin.go.jp/evaluation /seismic _hazard _map/lpshm/12_choshuki_dat/]的关东东海地区的北纬呈现35.5°的东西剖面。太平洋板块、菲利平海板块和关东沉积盆地等，表现为水平方向交界界面深度变化的层结构。除了地下构造模型的构建和公开之外，地震模拟代码和计算机的发展也取得了惊人的进展。例如，GMS [Aoi and Fujiwara (1999)]，SPECFEM [Komatitsch and Tromp (1999)]，SES3D [Gokhberg and Fichtner(2016)]和OpenSWPC [Maeda et al.(2017)]等公开了并行地震震动计算代码。通过与非均质结构模型结合使用，可以实现现实的地震震动模拟，大大促进了1hz以下低频地震震动传播的建模研究。例如，传播盆地堆积层的周期数秒以上的稍长的周期地震[例如Sato et al. (1999)，Ji et al. (2000)，Furumura et al.(2001)，Furumura和Hayakawa (2007)，Aoi et al. (2008)，Iwaki和Iwata (2008)，Graves和Aagaard(2011)，Yoshimoto and Takemura (2014ab)，Takemura et al. (2015b)，Asano et al.(2016)]，在俯冲带之后续波[例如，Martin and Rietbrock (2006)，Miyoshi et al. (2012)，Garth and Rietbrock (2014，2017)，Maeda et al. (2014)，Shiina et al. (2014)，Takemura et al. (2015cd)，Yu et al.(2017)]，海水层对地震震动的影响[例如，Shapiro et al. (1998, 2002)，Furumura et al. (2008)，Petukhin et al. (2010)，Nakamura et al.(2012、2014、2015)，Tonegawa et al. (2015a)，Guo et al.
