Pixel offset map showing how much each pixel changed, which is particularly useful when InSAR data was unable to image deformation because the change was simply too great. Pixel offsets are measured in meters. Fissure locations come from the previous PHIVOLCS fissure map. Note the coincidence of fissures along the Pansipit River Valley, which also marks a stark difference in deformation. Geographic and color sequence explanations, Valley Fault Zone, and fissure locations added by Temblor. Credit: Mary Grace Bato and Paul Lundgren, NASA JPL-Caltech, ESA
