Adak, Alaska Tsunami Forecast Grids for MOST Model
The Adak, 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: 60 arc-sec, 90
arc-sec in x direction. 90 arc-sec, 105 arc-sec in y direction. B Grid Resolution:
13.3333 arc-sec in the x direction. 12 arc-sec, 20 arc-sec in the y direction. C Grid
Resolution: 2 arc-sec in the x direction. 3 arc-sec, 4 arc-sec in the y direction.
