| Zusammenfassung |
| The Joint Australian Tsunami Warning Centre uses the T2 tsunami scenario
database to provide forecast guidance for potential tsunami threats to the
coastlines of mainland Australia and its external territories. This study
describes a method for generating coastal tsunami warnings from model data
obtained from the T2 scenario database. Consideration of observed coastal
impacts for nine past events leads to retrospective or "ideal" warning
schemes being designed. The 95th percentile values of maximum amplitude
within designated coastal zones are examined and thresholds that produce the
best match for the ideal schemes are selected. This empirical method is
impact-based and allows the T2 scenarios to be used as a proxy for potential
impacts on the coast in order to generate warnings for the Australian region. |
