.... The table also involves a fatal mistake. The tsunami height for Myojin should read 0.3 m at Hachijojima Island about 300 km south of Tokyo instead of 7 m. The writers wonder where such a high value came from. More detailed features of respective eruptions are given in our Table 1. As can be seen in Figure 1...
