earthquakes under seafloor can lead to tsunamis
A ridge with transverse faults is formed, where new oceanic crust (seafloor) is formed.

Seafloor Spreading
large regions of the seafloor that appear flat but are not
Seafloor continues to move away from the mid-ocean ridge and eventually comes into contact with another plate boundary. Ocean plates subduct underneath continental plates and are forced down into the lithosphere
Old seafloor rock is subducted into the Earth's mantle at deep-sea trenches, where it is melted and recycled. This process is part of the tectonic plate cycle, where old seafloor is continuously being consumed and regenerated.
Seafloor spreading happens when two tectonic plates move apart. Magma rises up from the mantle through the gap, creating new oceanic crust. As the plates continue to move apart, the new crust pushes the older crust away, causing the seafloor to spread.
They proved that the seafloor was spreading.
