  • Tsunami means "harbor wave" possibly getting its origins from being nearly undetectable until it reaches land where it does its devastation.
  • Along the Washington and Oregon coasts, scientists guess that a devastating tsunami has a good chance of happening in the next 40 years
  • In Hawaii, tsunamis are nearly common with a few dozen occurring over the past 100 years.
  • In the past 60 years, America has had 6 of these disasters kill over 350 tsunami victims along the West Coast and Hawaii.
  • The number of tsunamis per year is rising and the death tolls are climbing - partly due to increasing populations along Coastlines.
  • 80% of tsunamis occur in the Pacific Ocean.
  • Tsunamis travel 400-500 miles per hour in the open ocean. The waves slow and become taller as they approach land.
  • Tsunamis are not seasonal but may occur any time. Since they are usually triggered by earthquakes, there is little or no warning that they are approaching.
  • Waves are commonly 10 or 20 feet high, but have been over 100 feet high. A 10-foot wave can cause plenty of destruction requiring relief efforts.
  • A tsunami is not just one wave, but a series of waves and it may be many minutes from the first wave to the next which may be much larger than the first.
  • Tidal wave is a misnomor since tides have nothing to do with tsunamis.
