  Wet-dry interface which appreciably increases accuracy of tsunami simulations
with the MOST model (Method of Splitting Tsunamis, adapted by the NOAA for
tsunami forecasting operations) is highlighted here with a few comparative
simulations. The new solution, termed Cliffs, exceeds all MOST versions in
accuracy of computing later waves. This is demonstrated with simulation of the
Tohoku-2011 tsunami to Monterey Bay, CA, and into fiords, bays, and inlets of
southeastern Alaska, followed by comparison with tide gage records.
