What is a tsunami?

What is a tsunami?. “Near the source of submarine earthquakes, the seafloor is ‘permanently’ uplifted and down-dropped, pushing the entire water column up and down. The potential energy that results from pushing water above mean sea level is then transferred to horizontal propagation of the tsunami wave”.
