Introduction A hazard is a potential to cause harm, damage, breakage and destruction to property or even death to animals. It can also be a source of danger that is likely to result in an accident if undue care is not exercised. It can as well be considered a possibility of occurrence of a misfortune ( Raymond Agius, 2009). Other viable definitions include a situation posing a level of threat to life, health, property or environment. A hazard is equally considered anything that is unsafe or unhealthy that has or might cause people harm. It is an accident waiting to happen. Hazards are classified into the following groups: Physical hazards, biological hazards, Economic hazards and chemical hazards. Physical hazards are the forms of hazards most commonly experienced in the world. They include natural calamities and unsafe conditions which can cause injury, illness, suffering and even death. A tsunami is a type of physical/natural hazard comprising of a series of waves, made in an ocean or other water body caused by an earthquake (earth movements), impact of a meteorite, landslides and even volcanic eruptions (Geology.com, 2005). Tsunami waves are very huge, long and destructive and may extend to 100 km along the ocean. The tsunami waves rise as they approach the shores of the ocean. These huge waves travel so fast and sometimes at 700 km/h. (Gardimer, Lisa, 2005) Tsunamis are also caused by sudden and abrupt motion of the ocean floor/crystal rock breakage and displacements, powerful volcanic eruptions and in some cases underwater landslides. Earthquakes occur at approximately 900,000 worldwide yearly (UpSEIS, 2007). The most Tsunami prone areas in the US include areas of plate subduction. This is a zone where an oceanic plate is forced down the mantle by plate tectonic forces. There exists an enormous friction between the subducting plate and the overriding plate. The friction prevents any form of movement, including the sliding of the overriding plate leading to an accumulation of energy over a long period ultimately exceeding the friction leading to a sudden explosion and motion causing a tsunami. The moving wave, tsunami races away from the epicenter (area of earthquake occurrence/origin) gradually leading to destructive waves called the tsunami. The tsunami travels at an extreme speed over the open ocean reaching the continental lands faster than any meaningful control of its destruction (Geology.com, 2005). Tsunamis are also caused by rock falls and other impulsive generic sources. Figure 1. Earthquake There are several ways of identifying the tsunami prone areas in the world. These regions normally lie along the shores of the oceans like the Pacific Ocean and Indian Ocean. This makes some of the U.S coastal cities casualties to the adverse effects of the tsunami. The Oregon coastal communities of 26 cities in the U.S face significant threats of tsunami occurrence and possible inundation due to the effects of the catastrophic phenomenon. These coastal lands are majorly accommodation and food services, retail trade, manufacturing and entertainment sectors. Any possible tsunami occurrence in this area may be very fatal and costly. The Mid Eastern and the Eastern United States are believed to be most prone areas especially California and Alaska. These areas have also experienced considerable tsunami damages: Bost
