How do tsunamis form step by step?

Most tsunami are caused by large earthquakes at the seafloor, when large slabs of rock are forced to move past each other suddenly causing the overlying water to move. The resulting wave moves outwards and away from this event.

Steps on how tsunamis form?

The seabed shifts – two plates shift during an earthquake. The tsunami begins – Pulled down by gravity, the ridge collapses, triggering a series of smaller waves. The waves travel outwards, like when a pebble thrown in a pond ripples. Crossing the ocean- The deeper the water is, the faster the tsunami travels. Approaching land – the waves slow down as they cross shallower coastal waters. Reaching the shore – before each wave breaks; the sea withdraws up to 1km, then surging forwards, creating a towering wall of water.

Rarely, a large body from space, such as a meteorite, can cause a tsunami. Most often, tsunamis start from underwater earthquakes that happen along tectonic plate lines.

Then, what are tsunamis and how they form?

Tsunamis are large waves, usually caused by volcanic or earthquake activity under the ocean. They occur due to an earthquake, volcano or landslide happening on the ocean floor, causing water to be displaced. Tsunamis are large waves, usually caused by volcanic or earthquake activity under the ocean.
