Cross‐correlating seismic random signals, such as coda waves or ambient noise, at two sites can extract seismic wavefields as if a source is at one site and a receiver is at the other if certain conditions are met (e.g., Aki, 1957; Campillo and Paul, 2003). Given the recent development of dense seismic network, the last decade has witnessed the rapid emergence of imaging Earth’s local (Nagaoka et al., 2012), regional (Shapiro et al., 2005; Nishida et al., 2008; Lin et al., 2011), and global (Nishida et al....
