We describe the recovery of coastal landforms in Aceh, Sumatra after the hugely destructive Indian Ocean tsunami of December 26, 2004, using three sets of IKONOS images at a resolution of 1 m.The image sets were taken about two years before the tsunami, immediately following the tsunami, and about one year after the tsunami.We found a remarkably efficient recovery in progress, building new depositional forms seaward of the eroded coastline that effectively obliterate the morphological signals of the tsunami. Such detailed observations covering a long stretch of coast are now possible due to the availability of high-resolution satellite images.To the best of our knowledge this is the first time-based study of the recovery of a long stretch of coast (175 km) after catastrophic destruction by a tsunami.We suggest that tectonic coasts, like the one discussed here, may undergo similar changes periodically on a geological time-scale.Thus, it is possible that morphological evidences of catastrophic tsunamis are not necessarily preserved in the geological record.
