Tsunami- is a series of castrophic ocean waves of volcanic origin generated by earthquakes, volcanic eruption, and landslides beneath the ocean floor. They are the world's most powerful wave. They are not generated by gravitational pull coming from the sun or moon. Due to the height only being a few meters high and the length being able to spread over 750 kilometers tsunami's can go undetected until they reach shallow waters along the coast. They are said to be un-harmful in deep waters. .
There are three physical processes that develop tsunamis. Generation, propagation, and inundation. Generation is caused when there is a disturbance on the ocean floor like fault movements. Fault movements can help with the interpretation of the seismic data being collected. Propagation is the transport of seismic energy away from the quake/fault through wave movements. At this point a wave linear theory is applied. This theory helps to predict the wave depth and length, which helps to determine the speed of tsunami. During this point the wave direction can change and conversion can occur on the sea floor. The final process is inundation when a tsunami comes ashore as a breaking wave. When this occurs the height of the wave is so large that linear theory can no longer account for the interaction between the water and the shoreline. When this happens flooding can occur inland causing major damage.
Tsunami's have occurred and caused serious damage and harm in several parts of the world mostly in the Pacific Ocean Rim. Within the past 10 years 10 tsunamis have taken over 4,000 lives. These disasters have occurred in Nicaragua and Papua New Guinea, Hawaii and believe it or not Alaska. One of the most recent tsunamis to occur was that of in Papua New Guinea in the many villages of Sissano, Arop, Warapu and other villages in between the Sissano Lagoon. This disastrous tsunami happened a little over two years ago on July 17, 1998.
A tsunami is like a wave train or series of waves in the ocean. ... Tsunami is a Japanese word with an English translation "harbor wave". There are many ways for a tsunami to form. ... Just like other waves, tsunamis begin to lose energy as they rush onshore. ... Tsunamis can move faster than a person can run. ...
At that moment a tsunami is born. "Once generated, a tsunami behaves similarly to a wave produced by dropping a pebble into a shallow pond" (Ocean World Encyclopedia, "Tsunami"). ... However, because the speed of the tsunami depends on the depth of the water; as it decreases, so does the speed of the tsunami. ... According to geologist and tsunami expert, Dr. ... The first objective is to be able to detect and locate the existence of all tsunami or possible tsunami causing earthquakes using a device called a seisometer. ...

INTRODUCTION 22 May 1960. The largest (recorded) earthquake in the history of the world tips the Richter Scale off the coast of Chile, South America, with a magnitude of 9.5. Total devastation is estimated at $550 million in property damage and the loss of over 2,000 lives. As magnificent and ...
Tsunamis are more commonly called "tidal waves" but actually have no relation with any form of ocean tides. ... Tsunami waves have been known to reach speeds of 1,160 to 1,280 MPH (miles per hour.) ... Large tsunami waves have been known to kill and injure thousands of people. As technology changes, science slowly progesses on being able to track tsunami waves. Tsunami waves are hard to predict because specialists have trouble deciding the actual intensity of the wave. ...
Tidal waves are called "tsunamis" by the Japanese. "Tsunami" actually means "harbor wave", and this kind of wave is very destructive. ... Landslides and volcanic eruptions or explosions can assist in forming tsunamis. ... Tsunamis cause much damage to many people and places when they strike. Unfortunately, there have been many terrible tsunamis throughout history. ...
A deadly tsunami devastated the Indonesian islands on Monday, leaving the death toll well above 100 and likely to increase with time. ...
