The magma spills over the ridge and pushes the old sea floor away toward a subduction zone where the old sea floor melts.

It is a place where volcanism or hot water heated by the underlying magma erupts on the ocean floor.
Magma erupts along mid ocean ridges forming new ocean floor. Mid ocean ridges are found at divergent boundaries where two ocean plates are pushing apart.
Magma rises and slidifies and creates a new crust.

this usually happens when the sea floor spreads open.
Sea- Floor Spreading molten material erupts through the valley that runs along the center of some mid-ocean ridges. This material hardens to form the rock of the ocean floor. Mid-ocean ridges an undersea mountain chain where new ocean floor is produced.
When magma pours through a rift onto the ocean floor, it can create new oceanic crust through the process of seafloor spreading. This can lead to the formation of mid-ocean ridges. Additionally, the contact between the hot magma and the ocean water can result in explosive volcanic eruptions and the release of gases and minerals into the ocean.
Nothing . . . tsunamis are ocean waves, not volcanoes.
Basalt is the iron-rich volcanic rock that makes up much of the ocean floor. It forms from the cooling and solidification of magma that erupts through underwater volcanic activity, such as mid-ocean ridges. Basalt is a key component of Earth's oceanic crust.
