Port Alexander, Alaska Tsunami Forecast Grids for MOST Model
The Port Alexander, Alaska Forecast Model Grids provides bathymetric data strictly
for tsunami inundation modeling with the Method of Splitting Tsunami (MOST) model.
MOST is a suite of numerical simulation codes capable of simulating three processes
of tsunami evolution: generation, transoceanic propagation, and inundation of dry
land. Tsunami waves are computationally propagated across a set of three nested grids
(A, B, and C), each of which is successively finer in resolution, moving from offshore
to onshore. Nearshore details are resolved to the point that model output can be directly
compared with tide gauge observations and can provide estimates of wave arrival time,
wave amplitude and simulation of wave inundation onto dry land. A Grid Resolution:
90 arc-sec. B Grid Resolution: 18 arc-sec. C Grid Resolution: 1 arc-sec in the x direction.
1.5 arc-sec in the y direction.
