Fig. 8From: Surface deformation of Asama volcano, Japan, detected by time series InSAR combining persistent and distributed scatterers, 2014‒2018LOS velocities along the two profiles P1P1′ and P2P2′ (Fig. 7a) that encompass NEF and SEF, respectively. LOS velocities along P1P1′ from the a ALOS-2, b ascending Sentinel-1, and c descending Sentinel-1 images. d–f Similar to a–c but for the profile P2P2′. Note the positive velocity represents LOS shortening, and the negative velocity represents LOS extension. Error bars represent the estimated uncertainties (Additional file 1: Fig. S4) for deformation velocitiesBack to article page
