Abstract
The generation mechanism of the Papua New Guinea (PNG) Tsunami in 1998 is investigated through a numerical simulation. Tsunami amplification effect in the shallow water region is also evaluated. There is still now ambiguity about the generation mechanism due to the lack of the exact bathymetry data in the shallow water region. But it is quite certain that, based only on the earthquake, the behavior of the PNG tsunami cannot be fully explained. The earthquake, followed by landslides or slumps triggered by the original earthquake, was the most probable cause of the tsunami. These kinds of tsunamis have occurred in the past and caused heavy damages. To minimize damages, a tsunami warning concept that measures tsunami directly is needed. The newly invented laser tsunami meter is one of the candidates for use in such a warning system.
