Tsunami a large ocean wave caused by earthquakes on the ocean floor.
													
																	Large wave produced by an earthquake on the ocean floor. 
									
	
		
	
																	A megatsunami is a tsunami a large wave due to displacement of a body of water with an initial waveamplitude height measured in several tens hundreds or possibly thousands of metres. 
																	This sudden motion could be an earthquake a powerful volcanic eruption or an underwater landslide. 
																	The impact of a large meteorite could also cause a tsunami. 
																	A tsunami is a large ocean wave that is caused by sudden motion on the ocean floor. 
															
													
									
	
		
	
																	Tsunami waves do not resemble normal u. 
																	A large wave formed by the displacement of water which was caused by an earthquake on the ocean floor. 
																	Normal tsunamis generated at sea result from movement of the sea floor. 
																	A tsunami is a series of waves in a water body caused by the displacement of a large volume of water generally in an ocean or a large lake. 
															
													
									
	
		
	
																	A tsunami is a series of large waves generated by an abrupt movement on the ocean floor that can result from an earthquake an underwater landslide a volcanic eruption or very rarely a large. 
																	Earthquakes volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami. 
																	Large powerful ocean wave caused by an earthquake is called a tsunamis what happens with ocean floor during a tsunami. 
																	Seismic sea wave tsunami a large ocean wave that often results from vertical displacement of the ocean floor during an earthquake. 
															
													
									
	
		
	
																	The ocean floor does nothing itself but to cause the tsunami an earthquake.
