摘要
A tsunami forecast method and device and a tsunami warning method and device. The tsunami forecast method comprises: a data acquisition step (S101) for acquiring spatial data of a tsunami propagation area; a propagation time calculating step (S102) for calculating, on the basis of the acquired data, and storing propagation time between neighboring grids; a time of arrival calculating step (S103) for acquiring the time of arrival of each grid in a to-be-selected grid group on the basis of the propagation time between the neighboring grids, and selecting a next wavelet source from the to-be-selected grid group on the basis of the minimum value of the time of arrival of each grid in the to-be-selected grid group, so that the time of arrival of a tsunami arriving at each grid in the tsunami propagation area is calculated, wherein it is possible for the to-be-selected grid group to be used as a set of grids of the wavelet source; and an outputting step (S104) for outputting the time of arrival of each grid in the tsunami propagation area. Thus, fast tsunami forecast and warning can be realized.
