Fig. 4From: Data assimilation with dispersive tsunami model: a test for the Nankai TroughForecast accuracy a and time lag b of the two models for various assimilation time windows. The forecast accuracy is used to evaluate the forecasted maximum amplitude of the first tsunami peak (Aida 1978). The time lag is used to examine the forecasted arrival time (Tsushima et al. 2012)Back to article page
