The succession of waves is called a tsunami.
A tidal wave is caused by an earthquake.

Valles Marineris is a massive canyon system that runs along the Martian equator. At over 4,000 km long, 200 km wide and about 7 km deep, it is larger than any of Earth's canyons, and is the largest known canyon in the solar system.See link for more information

what happens is the ocean floor does not just keep spreading.instead, it sinks beneath deep underwater canyons called deep- ocean trenches
V-shaped valleys in the continental shelf and slope are called submarine canyons. These are deep, steep-sided valleys that cut across the continental margin and are often formed by underwater processes such as turbidity currents or erosion by underwater currents. Submarine canyons can be comparable in scale to canyons found on land.
A valley underwater is called a submarine canyon. These can form through a variety of geological processes, such as erosion by underwater currents or the collapse of underwater sediment. Submarine canyons can be important habitats for a diverse range of marine life.
Submarine canyons. These are steep-sided valleys that cut into the continental slope and sometimes extend onto the continental shelf. Submarine canyons can be formed by various processes, including erosion from turbidity currents or underwater landslides.
Trenches
No, there are canyons in cold places and underwater.
At deep-ocean trenches, subduction allows part of the ocean floor to sink back into the mantle. The ocean floor does not just keep spreading. Instead, it sinks beneath deep underwater canyons called deep-ocean trenches. Where there are trenches, subduction takes place.

Slope canyons are narrow, deep channels carved into the seafloor on the continental slope. They are typically formed by a combination of erosional processes like underwater landslides, turbidity currents, and the movement of sediment down the continental slope. Slope canyons play a crucial role in transporting sediment and nutrients from the continental shelf to the deep ocean.
good stuff
Narrow deep valleys are called canyons. Canyons are typically formed by erosion from water or glaciers over long periods of time, resulting in steep cliff walls and a narrow channel at the bottom.
