Undersea earthquakes or volcanic eruptions.
A submerged flat-topped peak is called a "seamount." Seamounts are underwater mountains that rise from the ocean floor but do not reach the water's surface. They typically have a steep slope and a flat summit, and they are often formed by volcanic activity. Seamounts can host diverse marine ecosystems and are important for ocean biodiversity.
The islands of southern Europe, such as Sicily, Sardinia, and the Balearic Islands, are primarily formed by a combination of undersea mountains and volcanic activity. These landforms are geologically diverse, with some areas experiencing volcanic eruptions that have contributed to their formation over millions of years.
Undersea volcanic activity produces various geological formations and materials, including volcanic islands, seamounts, and hydrothermal vents. These eruptions release magma, which can solidify into new rock formations, and they also emit gases and mineral-rich fluids that support unique ecosystems. Additionally, such activity can create new oceanic crust and contribute to the geochemical cycling of elements in the ocean.
Volcanic arcs are usually island arcs off the coast of a continent, while volcanic mountain ranges are usually inland inside a continent. But the volcanoes of a volcanic island arc do form an undersea volcanic mountain range. So to some extent the difference is mostly a matter of terminology.

An undersea volcanic formation that does not rise at least 1000 meters above the surrounding sea floor is called a seamount. These underwater mountains are formed by volcanic activity and can vary in size and shape.

A tsunami is a large sea wave produced by a seaquake or undersea volcanic eruption.
