High-pass-filtered (7-km cutoff) close-up view of unwrapped interferograms around the center of the deformation dome. Each number indicates the InSAR pair in Table 1. Red triangles indicate major lava domes belonging to the Atosanupuri volcanic complex. Contour interval is 0.5 cm. Lower right: Topography of the Atosanupuri volcanic complex. Red dotted lines show the area of a small valley (or basin) between lava domes in the topography. Small white circles show fumaroles. The target area is shown in Fig. 1
