Figure 22. Modeled potential <strong>inundation</strong> by tectonic <strong>and</strong> l<strong>and</strong>slide-generated waves for the selected scenarios. The DEM corresponds to the present-day MHHW datum. Due to the steep topography,<br />
<strong>inundation</strong> areas for several <strong>tsunami</strong> scenarios have a common boundary, <strong>and</strong> the plotted extents <strong>of</strong> the <strong>inundation</strong> areas may overlay each other.
