Cordova, Alaska Tsunami Forecast Grids for MOST Model

browse graphic
The Cordova, Alaska Forecast 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 in x direction, 30 arc-sec in y direction. B Grid Resolution: 12 arc-sec in x direction, 6 arc-sec in y direction. C Grid Resolution: 4 arc-sec in x direction, 2 arc-sec in y direction.
