How are tsunamis created?

Tsunami, Japaneze for harbor wave, comes from the fact that the waves, as tall as 30 meters in some cases, seem to be created near the shore. The actual origins of a tsunami lie in the contact areas of tectonic plates.

If tectonic plates move one over the other they generate an earthquake and then the water from above is risen way above the sea level. When that water is then pulled down by gravity it creates waves that will go for many miles and will measure up to 30 meters in height.

A sign that a tsunami would attack a shore line is that the water retreats ar more than usual. In this case simply run away for more than 1-2 miles from the shore. Take care.
