Conditional Expected Tsunami Inundation for Hawaii

Values were reported for a priori estimates of expected tsunami inundation — conditioned by values for epicenter location and tsunami magnitude. Those values of conditional expected tsunami inundation (CETI) were restricted to coastal locations having historical observations of tsunamis. Here a method is developed and applied for interpolating between these existing CETI to obtain predictions at coastal locations not possessing historical tsunami data. The method uses the existing CETI for calibrating (by best-fitting) the functional shape provided by the output from Bernard's time-stepping linear two-dimensional difference equations over a mesh having spatial increments of about 5 km and time steps of l5 sec (prototype time). Coastal position is measured along the coast from a reference point. Graphs for the interpolated CETI are given for the five major Hawaiian islands, assuming a tsunami magnitude of 4 arriving from the north.
