WebDec 26, 2004 · The tsunami travel times contoured in Fig. 1 are inferred from arrival times for the smallest waves simulated by the MOST tsunami propagation model. The areas without contours delineate regions where arrival times are difficult to estimate because waves of similar small amplitudes arrive at different times from different "packets" and … WebThe speed of the fronts is governed by the varying water depth. The front propagating toward the center of the bay travels faster. At t = 25.0 s, the front propagating toward the center of the bay coalesces with the tsunami wave propagating away from the fault surface toward the coastline, to form a larger-amplitude wave.
