Defination Definition : Tsunami

Tsunami are a Japanese term which has been used to describe a large seismically generated ocean wave, produced by a submarine earthquake, landslide, or volcanic eruption.

The pronunciation for tsunami is “soo- nah- mee”, and comes from Japanese : tsu (port) + nami(wave).

Incorrectly referred to as tidal waves, Tsunamis have no connection with tides.

Did the earth move for you?

Richard Gross, a geophysicist with NASA’s Jet Propulsion Laboratory in California, theorized that a shift of mass toward the Earth’s center during the quake on Sunday caused the planet to spin 3 microseconds, or 3 millionths of a second, faster and to tilt about an inch on its axis.
