No they ARE caused by the recession of the first wave which IS caused by an earthquake.
The highest waves in the ocean are usually caused by a storm or earthquake. An earthquake at sea can cause mass destruction if the waves crash into land.
Huge earthquake-caused waves are called tsunami in Japanese.
Seismic waves are any waves that travel through the Earth. As such all earthquake waves are seismic waves, however not all seismic waves are caused by earthquakes.

Earth is the medium for earthquake waves.
Viberations caused by the Siesmic waves,
giant waves made by earthquakes is called tsunamis
The earthquake in Japan was caused like any other earthquake, by two tectonic plates hitting and moving each other. The tsunami in Japan was caused because the earthquake happened close to the surface of the earth in the lithosphere (crust). The seismic waves (mostly the Secondary waves rather than the Primary Compression Waves) shook the water and later became a giant tidal wave, which was the tsunami in Japan.
Earthquakes are caused by the slipping of rock under the crust. The waves still travel on the ground, as they would above water, but the waves would cause a tsumai to happen.
Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explotion.
