| Zusammenfassung |
| We present a highly accurate and computationally efficient method (herein,
the "wavefront orientation method") for determining the travel time of
oceanic tsunamis. Based on Huygens' Principle, the method uses an eight-point
grid-point pattern and the most recent information on the orientation of the
advancing wavefront to determine the time for a tsunami to travel to a
specific oceanic location. The method is shown to provide improved accuracy
and reduced anisotropy compared with the conventional multiple grid-point
method presently in widespread use. |
