Quick Tsunami Forecasting Based On Database
Po-Yu Lin
Abstract
We want to use a reliable method to predict tsunami very quickly on a personal computer basis. Through the computation of unit tsunamis, time series of water levels at certain locations along the Korean eastern coast are collected. To compute a realistic tsunami, the results are multiplied by real initial sea surface displacement at every location of unit tsunami for a real tsunami event. Then, summations of each value on time axis give real tsunami water levels. Only simple computation of the initial tsunami waves and manipulation of pre-computed data set or database, makes it possible to deduce tsunami heights and arrival time along the coast in a few minutes on PC.
In Taiwan, we want to use the COMCOT Program to establish the Taiwan Tsunami Propagating Database. We must define different earthquake magnitude, depth, location and fault parameters to estimate tsunami heights and arrival time along the coast of Taiwan. In the future, when a tsunami earthquake occurs, we can get earthquake parameters from Taiwan Earthquake Rapid Reporting System. We will deduce tsunami heights and arrival time along the coast Taiwan quickly and forecast in a few minutes.
