Abstract

Determination of the initial water surface displacement at tsunami source is an essential part of most of tsunami warning systems. Every minute is important in case of a near field event. We propose to determine initial sea surface displacement at tsunami source by measuring only a part of a measured wave profile – time series. The measured wave profile is an input data for initial wave shape determination algorithm. As is established, even a part of wave profile is enough to determine the shape with an appropriate precision. This paper provides numerical experiments that allow to determine the length of the necessary part of the measured profile. The results will help decreasing total time spent on tsunami forecast.
