DCCFs for the V.SFT2–V.SKD2 pair in the 2–4 Hz over the time period of 2012 and 2014. Temporal changes in seismic velocity are estimated by using parts between −10 and 10 s in lag time. The reference CCF is shown at the top by black solid curve, which is calculated by stacking DCCFs over 2012 and 2013. The bottom panel is a result of estimating dt/t on March 6, 2012
