Computational technology for constructing tsunami local warning systems

The theme of this work is the method of constructing local systems (LS) for early tsunami detecting, based on the results of mathematical modeling. This method suggests fulfillment of the specially organized series of computational experiments, on the results of which the rational network of hydrophysical gages is determined for the particular defended point and nomograms for estimation of the parameters of the wave's influence are calculated on the basis of the data of the operative tsunami registration on the gages. With the help of these nomograms, it is possible to accomplish operative forecast of the degree of tsunamidanger for the particular point in the real time regime with necessary advance time, high security and reliability. Actual realization of the suggested method was accomplished for one of the harbour on the Kamchatka's coast. On the basis of this work, below there will be demonstrated the main ideas of such method of constructing local systems.
