“…In this study, we adopted the latter granular material model and the method similar to Paris et al (2020). Titan2D (Pitman et al 2003;Patra et al 2005;Titan2D 2016) was used for the calculation of the granular mass material, and JAGURS (Baba et al 2017) was used for the calculation of the tsunami propagation. Titan2D is a depth-averaged model that stably calculates the rheological motion of a continuum granular mass using real topographic data.…”

“…The comparison of the computed and recorded data is arranged in four geographical sectors in Figure . The computed time series are shifted by up to 13 min to correct travel time errors associated with earth elasticity and water density variation (Baba et al, ; Tsai et al, ). The azimuthal distribution of the tsunami is strongly influenced by the primary wave components at 45, 60, and 90 min period and scattering by continental and insular shelves (Bai et al, ; Cheung et al, ; Yamazaki, Cheung, Pawlak, et al, ).…”

“…A number of studies have attributed the observed delay of arrival to additional physical features including thermal or salinity‐based density stratification (Allgeyer & Cummins, ; Watada, ), compressibility of the water column (Allgeyer & Cummins, ; Dalrymple & Rogers, ; Wang, ; Watada, ), and elastic deformation of the underlying solid earth (Allgeyer & Cummins, ; Eyov et al, ; Watada et al, ). Taking a number of typically neglected effects together, the phase speed of surface gravity waves is reduced compared to that of an incompressible fluid due to the combined effects of compressibility, stratification, and elasticity (Baba et al, ). Wang () introduced a depth correction in a shallow water model in order to mimic the effects of compressibility without changing the governing equations.…”
