Was used in referring to major flooding along the coast due to earthquake 'tidal waves', which is used are widespread, as well as waves caused by an earthquake in the sea 'seismic seawave' which among scientists word. a 'tidal wave' of this name. The tsunami abuse Although the impact of the tsunami on the coast depend on. When the tide of tsunami waves crashing against the shore. But the tsunami did not correlate with the level of the tide water level, which was the result of an imbalance results from the gravitational pull of the moon. The sun and the Tsunami Tidal waves because it is not a process of tidal waves take centuries to cover coastal erosion. The tsunami that could change the landscape. At the coast in a short time, the word 'seismic sea wave' cause. Misleading as the word 'seismic' which is associated with an earthquake causing a tsunami alert, but it can be caused by the phenomenon. The Non-seismic Such as landslides or The result of a meteor hitting the tsunami is not a direct reaction to the earthquake, but only a reaction caused by the earthquake caused the collapse or landslide. Meteor chunk or into the sea The mass was replaced with a reaction force. Causing huge waves underwater, which is the tsunami itself, which would be known as the 'Non-seismic sea wave' like a tsunami called Seismic sea wave that caused the event. when the earthquake occurred in the ocean near the coast, or to build a massive earthquake. Happening underwater energy to roll out in all directions from the source that is spread out around the center of the affected area. Seismic waves are quite big enough when. Log on to the actual situation in the open ocean, deep water will swell like a wave runs along the surface. The ship can sail on the waves, but the waves are moving up. Shallow waters near the coast, it will move to dart onto the shore, sometimes up to 35 m (2,000 ft) tsunami is moving very fast. The speed of 1,000 km per hour (630 m / h), the alarm can not be done in time.
