Abstract
The post-tsunami runups on the damaged Andaman Sea coastline of Thailand from the tsunami of 26 December 2004 were surveyed by Thai and Korean teams for 99 transects from 23 January to 7 February 2005. The highest runup in Thailand was 15.68 m at Cape Coral, in Phang-nga province, and the longest inundation distance was 3 km at Bang Nieng, in Phang-nga province. The causes of the variation in runup were analyzed by using the method of splitting tsunami (MOST) model, tide gauges, satellite imagery, and field data with topographic charts. The distribution of runups reflects the effects of bathymetry, coastal topography, coastline configuration and slope, the pattern and density of land use, and the biological and geomorphological characteristics of offshore and near-shore areas.
