^aFP1 and FP2 are two fault planes because of the double couple
^b SC1 and SC2 indicate the scaling laws of Utsu (2001) and Murotani et al. (2013), respectively. Length (L), width (W), and slip amount (D) of a finite rectangular fault are given by these scaling laws using the M _w
^a,b The initial tsunami height conditions of src01, src02, src03, and src04 shown in figures are yielded by the pairs of FP1/SC1, FP1/SC2, FP2/SC1, and FP2/SC2, respectively
^c The tsunami data stations are shown in Fig. 2. Selected tide gauge stations are located within a 2-h tsunami arrival time
