From: Combined use of repeated active shots and ambient noise to detect temporal changes in seismic velocity: application to Sakurajima volcano, Japan

Fig. 7

Comparison of temporal changes in seismic velocity with those of areal strains calculated from GNSS data. Red plus symbols indicate the areal strain of a triangle composed of three GNSS stations of Sakurajima, Kagoshima2, and Kagoshima3. Blue dots indicate the relative velocity changes estimated by seismic interferometry. The results from the seismic interferometry analysis are stacked values for all station pairs. A median filter with a time window length of 10 days is applied to the both data. Two bar plots indicate monthly precipitation (cyan) and the number of explosions per month (red), respectively
