MOESM2 of Combined use of repeated active shots and ambient noise to detect temporal changes in seismic velocity: application to Sakurajima volcano, Japan

Additional file 2. Examples of sensitivity kernels in 2D and 3D at a lapse time of 10 s. Upper left panel shows a sensitivity kernel in 2D based on diffusion model. A yellow star and a red triangle indicate source and receiver, respectively. Upper right panel is a projected plot of the sensitivity kernel in upper left panel. A sensitivity kernel in 3D based on diffusion model and its projected plot are shown in lower left panel and lower right panel, respectively.
