This study aims to evaluate the effectiveness of numerical simulations in reproducing long-time tsunami propagation along the coast following the 2016 off-Fukushima earthquake.
Utilized a nonlinear long-wave simulation for tsunami data.
Constrained tsunami source by offshore tsunami waveforms from a dense seafloor observation network.
Compared simulations at nearshore and coastal water-level stations.
Analyzed tsunami amplitude envelopes over long times.
Simulations reproduced the largest tsunamis accurately at nearshore and coastal areas.
Better reproduction of tsunami decay was observed in nearshore regions compared to coastal ones.
Reproducibility errors were larger than source estimation uncertainties, indicating modeling improvements are needed.
Various simulation setups provided partial improvements in model accuracy.
