Ship distributions 24 min after the 2011 Tohoku tsunami generation identified from AIS data, and simulated maximum tsunami current. The rectangular area in a is enlarged in b. Labeled 13 ships (#1–#13) are used to evaluate tsunami currents in this study (Table 1). Another three ships (*1–*3) are not used due to data quality issues (Inazu et al. 2018). Dashed isobaths of 100 m and 500 m are shown in addition to the Japan Trench. Solid contours indicate the cumulative tsunami source of Hossen et al. (2015)
