Abstract

This article aims to build the similar understanding of run-up concept and to review the "map of t,'}iinami risk analysis in Pacitan" released by Balai Pengkajian Dinamika Pantai (BPDP)-BPPT Indonesia. We also propose similar understanding of risk definition related to the natural hazards, such as tsunami. The investigation used comparison method between 2 maps, i.e. tsunami risk map by BPDP and our tsunami risk map. Based on the comparison result, we found a misconception of rim-up in the tsunami risk map produced by BPDP. There is no differentiation between run-up and water-height over the land. It should be revised to avoid it from the incorrect rim-up definition. We also found if it was also mentioned as a "map of t.\imami risk analysis" while the analysis result was not performed in that map. Therefore, it is necessGlY to understand the run-up concept and risk concept first prior to map those phenomena.
