Tectonic earthquakes are a particular kind of earthquake that are associated with the Earth’s crustal deformation; when these earthquakes occur beneath the sea, the water above the deformed area is displaced from its equilibrium position. Tsunamis have a small amplitude (wave height) offshore, and a very long wavelength (often hundreds of kilometers long, whereas normal ocean waves have a wavelength of only 30 or 40 meters), [30] which is why they generally pass unnoticed at sea, forming only a slight swell usually about 300 millimeters (12) above the normal sea surface. This is a natural disaster that is caused due to the volcano eruption in the ocean beds. NOAA’s Tsunami Warning System (TWS) monitors the Pacific Basin for potential tsunami activity. This is proven to lead to huge effect in closed bays and lakes, but an open oceanic landslide large enough to cause a tsunami across an ocean has not yet happened since before seismology has been a major area of scientific study, and only very rarely in human history. Tsunami may not be one giant wave but a series of waves that come to the coast in a short interval. The first wave to reach the shore may not have the highest run up. In the middle of the ocean surface, this wave might be seen as a gentle swell and fall of the ocean surface and does not represent a major hazard to boats and ships. While everyday wind waves have a wavelength (from crest to crest) of about 100 meters (330 ft.) and a height of roughly 2 meters (6.6 ft.), a tsunami in the deep ocean has a much larger wavelength of up to 200 kilometers (120 mi).
