Comparison of earthquake source models for the 2011 Tohoku event using tsunami simulations and near field observations

Follow the links below for additional figures and data sets that were used to create them. Some data processing Python scripts are also included.

**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.
