a Spatial distribution of inter-annual vertical displacement in the Tyungyulyu area from Borogontsy to Tyungyulyu. T1–T3 denote sites selected for extracting the time-series displacement data shown in b. Stars indicate the reference points used to calibrate InSAR phases; b Time-series plots for the three selected sites shown in a; c, d, and e Enlarged view of inter-annual vertical displacement in c Syrdakh, d Oltyokhsky and e Balyktakh, respectively; f, g, and h Pleiades-1 images captured f in 2013 over Syrdakh, g in 2013 over Oltyokhsky, and h in 2019 over Balyktakh, respectively
