Abstract


Facing the rage of nature appears to be unavoidable with its catastrophic impact on human life. However, every event is an opportunity to learn and set control measures to avoid or at least minimize the damage as much as possible. One of the most devastating natural phenomena is Tsunami. Pacific region is one of the most impacted areas in the world that is affected by this type of incident. A comprehensive record of southeastern islands in Hawaii was gathered as a comma-separated values file for measuring heights of Tsunami waves at coastal locations. The database was modified and stratified for trending and descriptive analysis using a unique approach through the statistical process control (SPC) platform. Quantitative analysis of the database showed Tsunami in 1946 was the strongest one with destructive waves striking most locations. Control charts for separate and averaged Tsunami incidences showed the average wave heights, upper tidal thresholds and excursions in the wave level in the recorded locations. Some preceding points before the apparently highest waves showed warning signals of tidal drift from the mean coastal Tsunami wave level. Fast, simple and inexpensive SPC methodologies can be used as a quantitative tool in crisis risk evaluation, decision-making and resources management.
