Figure 2
Coherence of three interferograms from Track 54, Swath 1. Interferograms between January 1, 2015, and 3 different dates: (a) before the event - March 2, 2015, (b) soon after the event - May 13, 2015, (c) significantly after the event - January 18, 2016. Note that the year-long interferogram has higher coherence than the 4.5 month interferogram, except for in regions with significant relief, such as the coastal escarpment north of Taltal. (d) Timespan of interferograms shown in a–c (blue bars), relative to timing of 24–26 March rain event (red bar). T: City of Taltal, RC: Rio Chaco, PF: Paposa Fault. All available dates shown in Supplementary Figure 1. Figures generated using Generic Mapping Tools50, v. 5.2.1.
