How does a tsunami recede after it crashes?

After a tsunami crashes onto the shore, it recedes due to the gravitational pull of the ocean, which causes the water to flow back towards the sea. The energy that generated the tsunami dissipates as the wave travels inland, causing it to lose momentum. The retreating water may also create strong currents, pulling debris and sediment back into the ocean. This process can be rapid and may lead to dangerous conditions as the water moves back out.
