Use of numerical simulation as a means of Tsunami warningD
|
´˜^i‰pjF
Possibility of quantitative forecasting of local tsunamis sufficiently before thier arrivals, by use of the super computer, is examined. Provided that the initial tsunami profile can be determined within a few minutes after an earthquake by such a method as proposed by Izutani and Hirasawa, the tsunami numerical simulation based upon the linear long wave theory can be finished within two minutes and give practically accurate tsunami heights at every 200 m along the castline of the Sanriku district extending from 41ß30'N. to 36ß20'N.
