ALOS/PALSAR data fromJapanese Space AgencyAHERegion of fringes omittedfrom modeling (see text)5 km▲▲Figure 3. Original (wrapped) version of the ALOS track 335 ascending interferogram of 10 January–25 February 2011. Each fringerepresents 11.8 cm of apparent ground motion in the line-of-sight direction to the satellite. A region of narrowly spaced fringes is visibledue west of the Avon-Heathcote estuary (AHE). We have been unable to reliably phase connect these fringes with the remainder ofthe interferogram, so have left this region out of our current modeling. Compare with Figure 4, where a toward-satellite displacementis observed in this region using sub-pixel correlation techniques.10 kmRegion of towardssatellitedisplacementalso seen in ALOSinterferogramsmetersradar look▲ ▲ Figure 4. Ground displacement observed along line of sight to CSK satellite on ascending track, using sub-pixel correlation. Thistechnique provides measurements in regions where the DInSAR technique fails due to loss of coherence, though at lower resolution.Compare with other ascending track images in Figures 2, 3, S1, and S3. In this image, red denotes displacement away from the satelliteand blue denotes toward (opposite convention to other images in the paper).Seismological Research Letters Volume 82, Number 6 November/December 2011 793
