dc.description.abstract | Data from a field survey of the 2011 tsunami in the Sanriku area of Japan is presented and used to plot the distributionfunction of runup heights along the coast. It is shown that the distribution function can be approximated usinga theoretical log-normal curve [Choi et al, 2002]. The characteristics of the distribution functions derived from therunup-heights data obtained during the 2011 event are compared with data from two previous gigantic tsunamis(1896 and 1933) that occurred in almost the same region. The number of observations during the last tsunamiis very large (more than 5,247), which provides an opportunity to revise the conception of the distribution oftsunami wave heights and the relationship between statistical characteristics and number of observations suggestedby Kajiura [1983]. The distribution function of the 2011 event demonstrates the sensitivity to the number ofobservation points (many of them cannot be considered independent measurements) and can be used to determinethe characteristic scale of the coast, which corresponds to the statistical independence of observed wave heights. theoretical log-normal curve [Choi et al, 2002].
