Although such a great earthquake magnitude (M) resulting in a large tsunami has already passed, it would be invaluable to learn from a complete dataset ranging from a small tsunami generated by an M7.5 earthquake to a large tsunami, such as the 2011 event, generated by an M9.0 earthquake. Approximately 4,000 points from the historical tsunami trace data and 2,300 measurement points from the 2011 tsunami, representing each area affected along the Tohoku coast, were used to create a plot of tsunami height versus earthquake magnitude. We discovered that the tsunami generated by the 2011 event was not the maximum recorded tsunami height in some areas because of their geographic location and the source areas of the historical tsunamis. Linear regression analysis was performed to fi nd a relationship between the maximum tsunami height and earthquake magnitude. We found that this characteristic could be classifi ed into three regions based on their coastal topography: the Sanriku coast of Iwate, the Sanriku coast of Miyagi and the coastal plain of Miyagi and Fukushima. Historical tsunami data were used to confi rm that it was possible to estimate the maximum tsunami height generated by a strong hypothetical earthquake. This new knowledge might be very important for disaster mitigation, planning and warning observations, together with reevaluating tsunami hazard estimations in other areas in Japan, based on these fi nding
