Cause And Causes And Effects Of Seismic Sea Waves

At first, tsunami, also known as seismic sea waves, are a series of enormous waves created by an underwater disturbance such as earthquake, landslide, volcanic eruption, or meteorite. A tsunami can move hundreds of miles per hour in the open ocean and smash into land with waves as high as 100 feet or more.

From the area where the tsunami originates, waves travel outward in all directions. Once the wave approaches the shore, it builds in height. The topography of the coastline and the ocean floor will influence the size of the wave. There may be more than one wave and the succeeding one may be larger than the one before. That is why a small tsunami at one beach can be a giant wave a few miles away.

All tsunamis are potentially dangerous, even though they may not damage every coastline they strike. A tsunami can strike anywhere along most of the U.S. coastline. The most destructive tsunamis have occurred along the coasts of California, Oregon, Washington, Alaska, and Hawaii. Actually, tsunami not only happened within the U.S., also at Chile, Japan, Netherland and some countries nearby

Stagnant and contaminated water leads to malaria and other diseases, causing illness, infection and death to spread rapidly. Soil becomes salinized from sea water and debris, effecting long-term yields of crops. The tall and fast-moving waves also damage property and permanently alter the landscape, sometimes wiping out entire islands. They destroy everything in their path, including buildings, trees, power lines, bridges, cars, boats and more, leaving behind them a mass of solid waste and debris that is almost impossible to clean up. They also destroy animal life, insects, plants and natural resources. Hazardous materials and toxic substances are also a concern, as asbestos, oil fuel and other industrial raw materials and chemicals often leak as a result of property
