The Earthquake that triggered the Tsunami was the noise that could be heard.
the tectonic plates
A earthquake on a sea floor
The Japanese Authorities warned of a possible 3 meter tsunami that could hit Japan at 04:00 GMT (1:00 pm local time) on February 28th, 2010.
With New Zealand being the result of two tectonic plates meeting, it is plausible that if one of these dropped at all or there was a big enough earthquake a tsunami could reach vast amounts of Australia's east coast
Bear in mind that it is not just the Richter scale measurement which determines the severity of a tsunami which results from an earthquake; the location of the earthquake is also relevant. And inland earthquake does not produce the same tsunami as an underwater earthquake. That said, 8.3 is an extremely powerful earthquake which could produce a tsunami that would travel for thousands of miles and cause immense dammage over a very wide area.
None.The Earth moves or a meteorite, earthquake, or other underwater occurrence can make a Tsunami form. But,Oil drilling in the ocean Could cause a small earthquake, but not enough to trigger a tsunami.
You can't. Earthquakes and tsunamis cannot be prevented.
It depends on the size of the earthquake. If it was just a very very minor shudder, then it would not make much of a tsunami, nor would it go very far. However, if there is an earthquake like the one that just hit Japan, then that could cross the pacific ocean.
When an underwater earthquake displacing a large volume of sea water the effect could be a tsunami (tidal wave).
Haiti's earthquake was not strong enough to produce a tsunami. The earthquake caused a lot of destruction in Haiti, but that was largely because the buildings in Haiti had not been designed to withstand earthquakes. The earthquake in Haiti had its epicentre on LAND not in the ocean. Thus there was no sea floor movement associated with the earthquake which could have produced a tsunami.
it could cause an earthquake and a tsunami. or a volcano to be formed
