a Wavefield of the No. 461 hypothetical tsunami at t = 0, 15, and 30 min. Yellow triangles represent coastal tide gauges. Dark green circles represent offshore bottom pressure gauges. b Observed (black) and predicted (green) waveforms of the No. 461 hypothetical tsunami at coastal tide gauges, considering forecast time windows of 10 min (left column) and 25 min (right column). As a hypothetical event, the observed waveforms were obtained by forward modeling. The range of one-sigma prediction is depicted by the light green color
