most catastrophic of natural disasters. Peaceful oceanside communities can be wiped from the face of the earth in seconds by the huge fast moving waves whose heights can reach
over one hundred feet, lengths up to sixty miles, and speeds averaging 450 miles per hour dependent on the depth of the water (Regulatory Intelligence Data, 1998). The predominant
thought in previous years was that tsunamis are most frequently caused by seismic activity, by earthquakes and volcanic eruptions (Regulatory Intelligence Data, 1998). Tsunamis can also be cause, however,
by the impact of meteorites or essentially any sudden disruption of the earths surface that is intensive enough to displace the water column of the worlds oceans (Regulatory Intelligence Data,
1998). It is important to note that recent research, despite earlier thought the contrary, has demonstrated that small asteroids, asteroids less than a kilometer in diameter, do not have
the power necessary to cause a tsunami (Science Letter, 2003). More often tsunamis can be traced to submarine landslides or slumps (Monastersky, 1999). For tsunamis that originate
as a result of seismic activity or submarine slumps, the energy that is being released into the water column originates at the bottom of the sea. When meteor impacts
are involved the same type of energy release occurs but it occurs at the ocean surface and is referred to as a supermarine event as opposed to a submarine event.
Whether a tsunamis originates under the sea or at the surface they are tremendously powerful and destructive. Submarine events, however, are typically more powerful and destructive than supermarine events.
Japanese in origin, the term "tsunami" contains two inner terms meaning respectively "harbor" and "wave". Tsunamis are distinguished from tidal waves in
