CSK data acquisitions over time at Villarrica showing data analyzed (blue circles) the timing of the 2015 eruption (red line), and the perpendicular baseline. Blue circles that are connected were the only small baseline interferograms that were coherent in the vegetated areas that surround the volcano for postings of 30 m. Because the subsets do not overlap in time and in the absence of clear deformation signals it is very difficult to properly tie them for a time series inversion
