“…Compared with earthquake‐based surface wave tomography, ambient noise tomography enables substantial additional coverage at short periods (Shapiro et al., 2005). Numerous array‐based tomographic methods have been developed to derive anisotropy from ambient noise, such as eikonal and Helmholtz tomography (Lin et al., 2009; Lin & Ritzwoller, 2011), wave gradiometry (Cao et al., 2020; De Ridder & Curtis, 2017) and beamforming (Soergel et al., 2023; Wu et al., 2023).…”
