Abstract
The fault failure process with time difference affects the initial generation of waveforms of tsunamis, which consequently changes the runup height on the coast. To examine the effect of time difference in fault failure process on the runup height, a numerical simulation was conducted assuming a number of virtual subsea earthquakes in the west coast of Japan. Results revealed that maximum runup heights along the east coast of Korea were minimal when the subfaults were aligned parallel with the shoreline. Meanwhile, if they were located perpendicular to the shoreline, the superposition effect of the initial surface by each subfault was noticeable, resulting in an increase in maximum runup height on the coast.
