| Abstract: | Runup data in Biak Island and itsnearby islets are described with discussions oftsunami magnitude and a few characteristics such aswitnessed arrival times, wave periods and wavenumbers. From an engineering viewpoint, a relationbetween inundation depth and current velocity on landis also described with relations between inundationdepth and degree of damage to houses and between sanderosion depth and current velocity in backshoreregion, based on data collected from the present andpast tsunamis. |
