Figure S1: DART plots. Observed and simulated response at each DART buoy studied. Time is in seconds from 05:46:24 UTC on 11 March 2011. The simulation is shown in two forms: unshifted (with instantaneous seafloor deformation at t=0) and shifted by the optimal time T_d as discussed in the text.
Raw data and processing scripts
See Figure 1 from the paper for locations of sites referred to below.
Figure S2: K factor plots.
The K factor (after Aida, 1978) is regarded as a correction factor to adjust the simulated tsunami so as to fit the actual tsunami averaged over observation points in a site. For example, if the K factor is greater than one, it suggests that the simulated tsunami was smaller than the actual tsunami. The factor κ is defined as a measure of the fluctuation in K. See figure for equations.
