“…Coda wave interferometry uses the differences before and after small disturbances to detect weak changes in propagation media. Presently, this method has been used to probe the relative location of seismic sources (Snieder and Vrijlandt, 2005;Sato, 1986;Robinson, 1987;Roberts et al, 1992;Qiao et al, 2014;Wang et al, 2010), to monitor rapid temporal changes in volcanoes (Grêt et al, 2005;Wegler, 2004;Ratdomopurdo and Poupinet, 1995), and applied to the time-lapse monitoring of rock properties in the laboratory (Grêt et al, 2006;Weaver and Lobkis, 2000). Snieder et al (2002) used coda wave interferometry to obtain the signal delay and estimated the nonlinear seismic velocity variations.…”
