“…As a result, FWT has been widely applied in global and exploration seismology (e.g., Choi & Alkhalifah, 2012; Lei et al., 2020; Mao et al., 2016; Pratt, 1999; Virieux & Operto, 2009).

Liu et al., 2022; Sheng et al., 2006; W. Wang, Chen, Keifer, et al., 2019; W. Wang, Chen, Lee, & Mu, 2019; Y. Wang, Miller, et al., 2019).…”
