The term "seismic sea wave" has been found in geological and oceanographic texts, and typically is another term for a tsunami. Earthquakes at underwater subduction zones (where one tectonic plate moves beneath another) are the leading cause of tsunamis. Not all tsunamis are caused by earthquakes, however; other causes may include underwater volcanos, landslides, and underwater explosions (such as nuclear devices).
The earthquake caused the tsunami in Japan. And plate tectonics - which have been going on under the earths surface since the earth formed - caused the earthquake.
No. Most tsunamis occur as a result of undersea earthquakes and there are no earthquake zones in any of the Great Lakes that can cause a tsunami. The only thing that could cause a tsunami on the Great Lakes is a large meteor impact, but no such impact has occurred since before the lakes existed.
The major ones result from sub-sea earthquakes in subduction zones. Others can be triggered by major undersea mud-slides or volcanic eruptions. The 19C eruption of Krakatoa (or Krakatau) raised a gigantic wave that raced right round the world, obviously diminishing rapidly with distance but creating terrible havoc in the region. The cause was a gigantic final blast that may have been from the magma chamber collapsing and sea-water suddenly quenching a huge volume of very hot rock and lava. However, I'm not sure if this can be called a tsunami.
The effect we now call tsunami has been happening since there have been oceans on the planet Earth (billions of years). There was no "First Tsunami"; the Japanese have been calling the effect 'tsunami' for many centuries.
not likely but it can happen ... if there is a tsunami
No, but they have been on Tsunami watch several times
As of 16 June 2011 15,372 deaths from the earthquake and tsunami have been confirmed. It is almost impossible to determine what was the cause of death for each individual. See the related link.
No because the Yakuza have been wiped out by a tsunami... Rumor has it that the Mafia paid the tectonic plates to cause it.
Titanic has been underwater since 1912.
Tsunamis have been striking America but not of the magnitude of 2004 Asian Tsunami or 2011Japan Tsunami. But still there are no such instruments or devices which could predict a tsunami or an earthquake.
