Tsunami simulation area and locations of the calculated assimilation data (red dots) using interpolation of the observed data at the S-net sensors (black dots). The blue and green rectangles show the locations of the two test fault models of the hypothetical giant earthquake (Mw8.8) and the Nemuro-oki earthquake (Mw8.0), respectively. Triangles demarcate the locations where the tsunami waveforms are compared in Figs. 4 and 6
